Sampling specific SOPs should also be reviewed prior to conducting field sampling activities at PFC sites. The information contained within this SOP is included within sampling specific SOPs as applicable. 2.0 SCOPE This procedure applies to all AMEC personnel and subcontractors who collect or otherwise handle samples of soil, sediment, surface water, and groundwater for analysis of PFCs. This SOP should be reviewed by all on-site personnel prior to implementation of field activities. 3.0 REFERENCES Transport Canada, 2013. Perfluorochemical (PFC) Field Sampling Protocol. May. Delta Consultants, 2010. Report of Investigation Activities at Select Firefighting Foam Training Areas and Foam Discharge Sites in Minnesota. February. MPCA, 2008. Closed Landfill Program Sampling Protocol for Monitoring Wells. October. 4.0 GENERAL Given the low detection limits associated with PFC analysis and the many potential sources of trace levels of PFCs, field personnel are advised to act on the side of caution by strictly following these protocols, frequently replacing nitrile gloves, and rinsing field equipment to help mitigate the potential for false detections of PFCs. Specific items related to field sampling are discussed below. 5.0 RESPONSIBILITIES Project Manager The Project Manager shall provide the Quality Project Plan (QPP) and installation-specific work plan, which shall include the sampling requirements for each site. The Project Manager will report deviations to this procedure to the Quality Control (QC) Manager and the AFCEC Contracting Office Representative (COR). Rev. 1 1 DATE STARTED: 07/21/2014 Field Manager The Field Manager shall ensure that samples are collected in accordance with the QPP, installation-specific work plans, and applicable SOPs. The Field Manager shall also be required to make rational and justifiable decisions when deviations from these procedures are necessary because of field conditions or unforeseen issues and report the deviations to the Project Manager. Quality Control Manager The QC Manager will be responsible for conducting field audits during sampling activities. During these audits, the QC Manager will ensure that field crews are adhering to the QPP including sampling techniques, field documentation, sample packaging, chain of custody documentation procedures, and equipment calibration. Field Personnel Field personnel assigned to sampling activities are responsible for completing their tasks according to specifications outlined in the QPP, installation-specific work plans, applicable SOPs, and other appropriate procedures. Field personnel are responsible for reporting deviations from procedures to the Field Manager. 6.0 PROCEDURES/CONSIDERATIONS The following are procedures/considerations to be made during field activities at potential PFC release sites. A summary of the prohibited and acceptable items for PFC sites is included in Table 1. A checklist, provided as Attachment 1, shall be used daily prior to the commencement of fieldwork to ensure the field team is in compliance with this protocol. Field Equipment  Do not use Teflon®-containing materials (e.g., Teflon® tubing, bailers, tape, plumbing paste, or other Teflon® materials) since Teflon® contains fluorinated compounds.  Do not use low-density polyethylene (LDPE) materials during sampling. High-density polyethylene (HDPE) and silicon materials are acceptable.  AMEC will use peristaltic pumps for groundwater sample collection at depths shallower than 25 feet. AMEC will use ProActive SS Pumps with PVC leads or Geotech SS Geosub pumps for groundwater sample collection at depths greater than 25 feet. These pumps are stainless steel and will minimize introductions of PFCs.  When using liners to collect soil samples during direct-push technology (DPT) or conventional drilling methodologies, acetate liners are to be used. Rev. 1 2 DATE STARTED: 07/21/2014  To avoid plastic coating or glue materials, do not use waterproof field books. Field reports will be documented on loose paper on masonite or aluminum clipboards (i.e. plastic clipboards, binders, or spiral hard cover notebooks are not acceptable) using a pen or pencil. Sharpies®/markers may be used.  Post-It Notes are not allowed on project sites.  Do not use markers other than Sharpies®markers. Pens will be used when documenting field activities in the field log and on field forms as well as labeling sample containers and preparing the Chain of Custody.  Do not use chemical (blue) ice packs during the sampling program. This includes the use of ice packs for the storage of food and/or samples. Field Clothing and Personal Protective Equipment  Do not wear synthetic water resistant, waterproof, or stain-treated clothing during the field program. Field clothing to be worn on-site should be restricted to natural fibers (preferably cotton) and not synthetic. Field clothing should be laundered avoiding the use of fabric softener. Preferably, field gear should be cotton construction and well laundered (a minimum of 6 times from time of purchase). New cotton clothing may contain PFC related treatments. Do not use new clothing while sampling or sample handling.  Do not wear clothing or boots containing Gore-Tex™ during the sampling program as it consists of a PFC membrane.  All safety footwear will consist of steel-toed boots made with polyurethane and polyvinyl chloride (PVC).  Do not wear Tyvek® clothing on-site since it contains fluorinated compounds.  Disposable nitrile gloves must be worn at all times. Further, a new pair of nitrile gloves shall be donned prior to the following activities at each sample location: - Decontamination of re-usable sampling equipment; - Prior to contact with sample bottles or water containers; - Insertion of anything into the well (e.g. HDPE tubing, HydraSleeve bailer, etc.); - Insertion of silicon tubing into the peristaltic pump; - Completion of monitor well purging, prior to sample collection; - Handling of any quality assurance/quality control samples including field blanks and equipment blanks; and, - After the handling of any non-dedicated sampling equipment, contact with non- decontaminated surfaces, or when judged necessary by field personnel. Rev. 1 3 DATE STARTED: 07/21/2014 Sample Containers  Different laboratories may supply sample collection containers of varying sizes dependant on the type of media to be sampled (e.g., soil, groundwater, etc.). However, all samples should be collected in polypropylene or HDPE bottles fitted with an unlined (no Teflon®), polypropylene HDPE screw cap.  Container labels will be completed using pen after the caps have been placed back on each bottle.  Glass containers should also be avoided due to potential loss of analyte through adsorption. Wet Weather  Field sampling occurring during wet weather (e.g., rainfall and snowfall) should be conducted while wearing appropriate clothing that will not pose a risk for cross- contamination. Teams will avoid synthetic gear that has been treated with water- repellant finishes containing PFCs. Use rain gear made from polyurethane and wax- coated materials.  Teams should consider the use of a gazebo tent, which can be erected overtop of the sample location and provide shelter from the rain. It should be noted that the canopy material is likely a treated surface and should be treated as such; therefore, gloves should be worn when moving the tent, changed immediately afterwards and further contact with the tent should be avoided until all sampling activities have been finished and the team is ready to move on to the next sample location. Equipment Decontamination Field sampling equipment, including oil/water interface meters and water level indicators, that are utilized at each sample location will require cleaning between uses. Alconox® and Liquinox® soap is acceptable for use since the Material Safety Data Sheets do not list fluoro- surfactants as an ingredient. However, Decon 90 will not be used during decontamination activities. Water used for the final rinse during decontamination of sampling equipment will be laboratory certified “PFC-free” water. For larger equipment (e.g., drill rigs), decontamination will be conducted with potable water using a high-pressure washer and then rinsed using potable water. Rev. 1 4 DATE STARTED: 07/21/2014 Personnel Hygiene  Field personnel will not use cosmetics, moisturizers, hand cream, or other related products as part of their personal cleaning/showering routine on the morning of a sampling event, as these products may contain surfactants and represent a potential source of PFCs.  Many manufactured sunblock and insect repellants contain PFCs and should not be brought or used on-site. Sunblock and insect repellants that are used on-site should consist of 100% natural ingredients. A list of acceptable sunscreens and insect repellents are listed in Table 1.  For washroom breaks, field personnel will leave the exclusion zone and then remove gloves and overalls. Field personnel should wash as normal with extra time for rinsing with water after soap use. When finished washing, the use of a mechanical dryer is preferred and the use of paper towel for drying is to be avoided (if possible). Food Considerations  No food or drink shall be brought on-site, with the exception of bottled water and hydration drinks (i.e., Gatorade® and Powerade®), which will only be allowed to be brought and consumed within the staging area. Visitors  Visitors to the site are asked to remain outside of the exclusion zone during sampling activities. Rev. 1 5 DATE STARTED: 07/21/2014 Table 1.

ERDC/CRREL TR-07-10. Rev. 1 1 DATE STARTED: 07/21/2014 4.0 DEFINITIONS Borehole - Any hole drilled or hydraulically driven into the subsurface for the purpose of identifying lithology, collecting soil samples, and/or installing monitoring wells. Core Sampler – A metal tube (probe rod), generally 4- to 5-feet long by 2.25- to 3.25-inch OD, typically utilized along with drive rods and a polyvinyl chloride (PVC) or acetate or equivalent liner that is used to collect soil cores utilizing a direct-push rig. Inside the probe rods are smaller diameter, center rods affixed with a solid drive tip that seals the lower end of the probe rods during pushing. After reaching the target depth, advancement is halted and the center rods and drive tip are removed, which opens the bottom end of the probe rods. A sample liner is attached to the rod string and is lowered to the bottom of the push rods, and the assembly is then advanced to collect the soil sample within the liner. The center rod string is withdrawn from the probe rods, and the liner is removed to access the recovered soil core. The process of direct-pushing and soil core recovery may be repeated within the same boring until reaching total boring depth. Composite soil sample – a combination of soil aliquots collected at various locations, or at various depths at a single location. Analysis of composite samples yields a value representing an average over the various sampled sites or depths from which individual samples were collected. Discrete soil sample – a discrete aliquot from a distinct sampling interval (of a specific sample size) that is representative of one specific location at a specific point in time. Drilling Jars – A set pair of linked, heat-treated steel bars. The jars may be attached to a wireline sampling string incorporating a split spoon or other impact sampler. The jars are used to drive the sampler into the soil ahead of the bottom of the borehole Split-Spoon Sampler – A steel tube, split in half lengthwise, with the halves held together by threaded collars at either end of the tube. This device can be driven into resistant (semiconsolidated) materials using a drive weight or drilling jars mounted in the drilling rig. A standard split-spoon sampler (used for performing standard penetration tests) is 2 inches in outside diameter and 1-3/8 inches in inside diameter. This standard spoon typically is available in two common lengths, providing either 20-inch or 26-inch internal longitudinal clearance for obtaining 18-inch or 24-inch long samples, respectively. Six-inch long sleeves (tubes) of brass, stainless steel, or plastic are commonly placed inside the sampler to collect and retain soil samples. A five-foot long split-spoon sampler is also available. A California modified split- spoon sampler is also commonly used. The design is similar to the standard split-spoon except Rev. 1 2 DATE STARTED: 07/21/2014 the outside diameter is 2 1/2 inches and the inside diameter is 2 inches. Shelby Tube Sampler – A thin-walled metal tube used to recover relatively undisturbed samples. These tubes are available in various sizes, ranging from 2 to 5 inches in outside diameter and 18 to 54 inches in length. A stationary piston device is included in the sampler to reduce sampling disturbance and increase sample recovery. 5.0 GENERAL Collecting soil samples is an important site characterization activity. Soil samples are used to determine the nature and extent of contamination, to identify hazardous substance source areas, and to determine the geotechnical, hydrogeologic, physical, and chemical properties of a site. Soil sampling strategies will be determined and documented before initiating sampling. Field conditions at the site may preclude collection at one or more predetermined sampling locations. Additional soil sampling may be required if unexpected subsurface conditions are observed during the course of the sampling. Proper sampling techniques, proper selection of sampling equipment, and proper decontamination procedures will eliminate cross- contamination and the introduction of contaminants from external sources. Soil conditions can vary widely at a hazardous waste site. Such variations can affect the rate of contaminant migration through the soil. Therefore, it is important that detailed records be maintained during sampling, particularly with respect to the sample location, depth, color, odor, lithology, hydrogeology, and readings derived from field monitoring equipment. Surface and shallow subsurface soil samples shall be described utilizing the Unified Soil Classification System and / or ASTM guidance D2487 Standard Practices for Classification of Soils for Engineering Purposes (Unified Soil Classification System), unless otherwise specified by the work plan. 6.0 RESPONSIBILITIES Project Manager The Project Manager shall provide the project work plan, which shall include the sampling requirements, locations and depths for the project. Field Manager The Field Manager shall ensure that soil samples are collected according to this technical procedure. The Field Manager shall also be required to make rational and justifiable decisions when deviations from this procedure are necessary because of field conditions or unforeseen problems. Rev. 1 3 DATE STARTED: 07/21/2014 Field Personnel Field personnel assigned to subsurface soil sampling activities during drilling or probing are responsible for completing their tasks according to specifications outlined in this SOP and other appropriate procedures. All staff are responsible for reporting deviations from procedures to the Project Manager or the Field Manager. 7.0 PROCEDURES 7.1 Equipment Equipment used to collect surface or subsurface soil samples may include, but is not limited to, the following items:  Stainless steel spoons/trowels;  Stainless steel hand auger;  Stainless steel split spoon, split barrel, or continuous sampler;  Stainless steel bowls/pans;  Field logbook and boring log (Not “write in the rain” © or other water resistant paper);  Pens;  Paper towels;  Aluminum foil;  Appropriate decontamination equipment;  Appropriate personnel protective equipment and safety equipment as specified in the Health and Safety Plan;  Sample cooler with ice;  Sample jars and labels;  Bubble wrap;  Chain-of-Custody forms;  Munsell Soil Color charts;  Grain size charts;  Hand lens;  Brass sleeves;  Brass caps;  Ziplock freezer bags; and,  Two stainless steel deionized water spraying devices.  Non PFC plastic sheeting  Non PFC tape Rev. 1 4 DATE STARTED: 07/21/2014 7.2 Decontamination Before collecting any soil samples, all sampling devices shall be decontaminated. If dedicated or disposable equipment is used, it will be rinsed with deionized water where applicable. Mobile decontamination supplies will be provided so that equipment can be decontaminated in the field. Each piece of sampling equipment shall be decontaminated before initiation of sampling operations and between each sample location and interval. Decontamination solutions shall be replenished between each site as needed. Spent decontamination fluids will be containerized properly labeled and appropriately disposed of according to the IDW plans addressed in the project specific work plan. 7.3 Surface Soil Sampling Any surface vegetation will be removed before sampling with a decontaminated shovel or sampling spoon. Surface soil samples may be collected as either discrete or composite samples. Each surface soil sample will be collected using either a stainless steel spoon or trowel. The sampler, wearing clean disposable nitrile gloves, will remove pebbles, roots, etc. from the mixture as the sample is collected. Each sample will be collected by thoroughly homogenizing material from the zero to 6-inch below ground surface depth interval (unless other depth intervals are specified in the work plan). A decontaminated stainless steel scoop or trowel will be used to remove a thin layer of soil from the area that comes into contact with the shovel (if used to gain a specific sampling depth). A second decontaminated stainless steel spoon or trowel will then be used to collect the soil sample. Each soil sample fraction collected will be thoroughly mixed (i.e. homogenized) using the sampling spoon or trowel. The homogenized material will then be divided among the appropriate sample containers. The sample containers will then be sealed tightly. Care should be taken to ensure the container (bowl, pan, etc.) used for homogenization and the sampling utensils do not interfere with the analytes of interest (e.g., an aluminum pan should not be used for soil samples submitted for inorganic analyses; only stainless steel bowls are allowed). All personnel who collect or handle the soil samples will wear disposable nitrile gloves to prevent cross-contamination and provide personal protection. New gloves shall be donned for sample collection at each location, or whenever gloves are torn or otherwise compromised. If collecting a composite sample, each aliquot will be collected by placing equal amounts of soil collected from multiple locations into a decontaminated collection container. The aliquots will then be combined (i.e. homogenized) using a spoon or trowel. The homogenized material will then be divided equally among the appropriate sample containers. Rev. 1 5 DATE STARTED: 07/21/2014 7.4 Subsurface Soil Sampling 7.4.1 Split-Spoon Sampling Split-spoon samples for chemical analysis are usually obtained in brass, plastic, or stainless steel sleeves. The type of sleeve to be used if applicable, along with the length and type of sampler, will be stated in the project work plans. The split-spoon sampler is connected to the drill rod string or a wireline sampling string and is driven by a drive hammer (140 or 340 pound, depending on the size of the sampler) or drilling jars into the undisturbed soil ahead of the bottom of the borehole. The procedure for collecting samples from the split-spoon sampler will be outlined in the project work plans. The standard procedure is described below.  Calibrate all field analytical and health and safety monitoring equipment according to the instrument manufacturer’s specifications. Calibration results will be recorded on the appropriate form(s) as specified by the project-specific work plans. Instruments that cannot be calibrated according to the manufacturer’s specifications will be removed from service and tagged.  Wear the appropriate personal protective equipment as specified in the project work plans and the applicable drilling method SOP.  Between each sampling location and prior to each sampling run, decontaminate the sampler, sleeves, and other nondisposable sampling equipment as described in SOP AMEC-10.  Advance the borehole to the desired depth or target horizon where the sampling run is to begin.  When the desired sampling depth or target horizon is reached, remove the drill bit or plug from inside the drive casing or augers.  Insert the sleeves into the split-spoon sampler (if determined necessary), connect the halves, and screw together the rear threaded collar and front drive shoe. Attach the split-spoon sampler to the bottom end of the drill rod string or wireline sampling string. Set up and attach the specified weight hammer, if used.  Drive the sampler into the soil at the bottom of the borehole. Record the type of sampler assembly and hammer weight on the Boring Log and/or other appropriate form(s), as specified in the project work plans. To minimize off-gassing of the volatiles, the sampler should not be driven until the sampling team is ready to process the sample.  Pull the drill rod or wireline sampling string up from the bottom of the borehole and remove the sampler. Rev. 1 6 DATE STARTED: 07/21/2014  Remove the drive shoe and rear collar from the sampler and open the split barrel.  If sleeves are used, remove the sleeves one at a time, starting with the sleeve adjoining the drive shoe. Observe and record the amount of sample recovery on the Boring Log. Any observed field problems associated with the sampling attempt (e.g., refusal) or lack of recovery should be noted on the drilling log.  If sleeves are used, select sleeve(s) to be submitted for laboratory analysis. Sample sleeve selection should be based on four factors: judgment that the sample represents relatively undisturbed intact material, not slough; proximity to the drive shoe; minimal exposure to air; lithology; and obvious evidence of contamination. The soil core should also be visually recorded on a soil boring log.  Appropriately label and number each sleeve or soil sample container to be submitted for analysis. The label will contain, at a minimum, the following information: - Project number; - Location ID; - Boring number; - Sample number; - Bottom depth of sleeve, if applicable; - Date and time of sample collection; - Parameters for analysis; and, - Sampler’s initials.  Document the sampling event on the Soil Sample Collection Field Sheet or an equivalent form as specified in the project work plans. At a minimum, this log will contain: - Project name and number; - Location ID - Date and time of the sampling event; - Drilling and sampling methods; - Sample number; - Sample location; - Boring number; - Sample depth; - Sample description; - Unusual events; and, - Signature or initials of the sampler. Rev. 1 7 DATE STARTED: 07/21/2014  Appropriately preserve, package, handle, and ship the sample in accordance with the procedures outlined in SOP AMEC-10 and the project work plans. The samples shall also be maintained under proper chain of custody. Samples stored on-site will be subject to the provisions of SOP AMEC-10.  Repeat this sampling procedure at the intervals specified in the project work plans until the bottom of the borehole is reached and/or last sample collected. 7.4.2 Core Sampling using Direct Push Technology (DPT) A core sampler may be used to collect subsurface soil samples. The procedure for collecting soil samples using a core sampler should be outlined in the project work plans. The standard procedure is described below.  Calibrate all field analytical and health and safety monitoring equipment.  Wear the appropriate personal protective equipment.  Between each sampling location and prior to each sampling run, decontaminate the sampler and other sampling equipment as described in SOP AMEC-10.  Advance the probe rods equipped with a solid drive tip to the desired depth or target horizon where the sampling run is to begin. After reaching the target depth, the center rods and drive tip are removed and a new PVC liner is attached to the center rod string.  Once the liner and center rods are inserted into the probe rods, the assembly is advanced to collect the soil sample within the liner. The assembly is pushed about 4 to 5 feet into the soil with a continuous, rapid motion. At shallow depths and/or in soft soils, the assembly may be advanced without impact from the drive hammer. At greater depths and in harder substrates impact from the drive hammer is likely required to advance the sampling assembly. The liner and center rods are withdrawn from the probe rods, noting which end of the liner is up.  The DPT contractor will cut the liner and present it to the geologist/engineer for inspection and sample collection. Upon receiving the liner, the field geologist/engineer will observe and record the amount of sample recovery and any associated problems.  Sample selection should be based on five factors: judgment that the sample represents relatively undisturbed intact material, not slough; proximity to the drive shoe; minimal exposure to air; lithology; and obvious evidence of contamination. The soil core should also be visually recorded on a Soil Boring Log. Rev. 1 8 DATE STARTED: 07/21/2014  Appropriately label and number each soil sample container to be submitted for analysis. The label will contain, at a minimum, the following information: - Project number; - Location ID; - Boring number; - Sample number; - Date and time of sample collection; - Parameters for analysis; and, - Sampler’s initials.  Document the sampling event on the soil sample collection field sheet or an equivalent form as specified in the project work plans. At a minimum, this log will contain: - Project name and number; - Location ID; - Date and time of the sampling event; - Drilling and sampling methods; - Sample number; - Sample location; - Boring number; - Sample depth; - Sample description; - Unusual events; and, - Signature or initials of the sampler.  Appropriately preserve, package, handle, and ship the sample in accordance with the procedures outlined in SOP AMEC-11 and the project work plans. The samples shall also be maintained under proper chain of custody. Samples stored on-site will be subject to the provisions of SOP AMEC-11.  Repeat this sampling procedure at the intervals specified in the project work plans until the bottom of the borehole is reached and/or last sample collected.

Proper collection procedures are necessary to assure the quality and integrity of all groundwater samples. Additional specific procedures and requirements will be provided in the project work plans, as necessary. 2.0 REFERENCES ASTM International, 2007, Standard Guide for Sampling Ground-Water Monitoring Wells, D 4448-01 (Reapproved 2007).

Well water enters the bladder through a one-way check-valve at the bottom. Gas is forced into the annular space (positive displacement) surrounding the bladder through a gas supply line. The gas displaces the well water through a one-way check-value at the top. The water is brought to the surface through a water discharge line. Gas (air or nitrogen) is provided by compressors or cylinders. (Note: Bladder pumps have either low density polyethylene or Teflon liners, and will not be used for PFC sampling). Peristaltic Pump – A peristaltic pump is a self-priming, low volume pump consisting of a rotor and ball bearing rollers. Tubing placed around the rotors is squeezed by the rotors as they revolve. The squeezing produces a wavelike contractual movement that causes water to be drawn through the tubing. The peristaltic pump is limited to sampling at depths of less than 25 feet. (Note: AMEC will use peristaltic pumps for all well sampling at depths 25 feet or shallower, utilizing silicon and HDPE sample tubing only). Rev. 1 1 DATE STARTED: 07/21/2014 Electric Submersible Pump – An electric submersible pump is an enclosed cylindrical tube containing a motor with rotary attachments. Well water enters the cylinder through a one-way check valve. Electrical power to the motor causes rotors or impellers to turn and displace the groundwater. (Note: Grundfos pumps have Teflon internals and Teflon coatings on the leads and will not be used to sample for PFCs. For water sampling done at depths below 25 ft bgs, only Proactive SS pumps with PVC leads or Geotech SS Geosub pumps will be used for PFC sampling, as these pumps are stainless steel and will minimize the introduction of PFCs due to sample collection.) Bailer – A bailer is an enclosed cylindrical tube containing a floating ball check-valve at the bottom. Lowering the bailer into water causes the ball to float allowing water to enter the cylinder. Raising the bailer through the water causes the ball to settle, creating a seal to trap the water so that it can be brought to the surface. (Note: bailers containing Teflon or LDPE will not be utilized for PFC sampling.) Dedicated Groundwater Monitoring Equipment – Dedicated groundwater monitoring equipment is used to purge and sample only one well. The equipment is installed and remains in the well for the duration of the monitoring program. Dedicated equipment does not need to be decontaminated between sampling events. 4.0 PROCEDURE This section contains both the responsibilities and procedures involved with groundwater sampling. Proper groundwater sampling procedures are necessary to insure the quality and integrity of the samples. The details within this SOP should be used in conjunction with project work plans. The project work plans will generally provide the following information:  Sample collection objectives;  Locations of groundwater samples to be collected;  Numbers and volumes of samples to be collected;  Types of chemical analyses to be conducted for the samples;  Specific quality control (QC) procedures and sampling required;  Any additional groundwater sampling requirements or procedures beyond those covered in this SOP, as necessary; and,  At a minimum, the procedures outlined in this SOP for groundwater sampling will be followed. Rev. 1 2 DATE STARTED: 07/21/2014 4.1 RESPONSIBILITIES Project Manager The Project Manager is responsible for ensuring that sample collection activities are conducted in accordance with this SOP and any other appropriate procedures. This will be accomplished through staff training and by maintaining quality assurance/quality control (QA/QC). Field Manager The Field Manager is responsible for periodic observation of field activities and review of field generated documentation associated with this SOP. The Field Manager is also responsible for implementation of corrective action (i.e., retraining personnel, additional review of work plans and SOPs, variances to QC sampling requirements, issuing nonconformances, etc.) if problems occur. Field Personnel Field personnel assigned to groundwater sampling activities are responsible for completing their tasks according to specifications outlined in this SOP and other appropriate procedures. All staff are responsible for reporting deviations from procedures to the Project Manager or Field Manager. 4.2 GROUNDWATER SAMPLING REQUIREMENTS 4.2.1 Equipment Selection and Sampling Considerations Purging and sampling equipment is constructed from a variety of materials. The most inert material [e.g., silicone and high-density polyethylene (HDPE)], with respect to known or anticipated contaminants in the well(s), will be used whenever possible. The various types of purging and sampling equipment available for groundwater sampling are described in ASTM Standard Guide for Sampling Groundwater Monitoring Wells, D 4448-01 (ASTM, 2007) or Collection of Groundwater Samples at Known or Suspected Groundwater Contaminated Sites or Compendium of Superfund Field Operations Methods (EPA, 1987). For PFC sampling AMEC will use peristaltic pumps (with silicon and HDPE tubing) for groundwater sample collection at depths shallower than 25 feet. AMEC will use Proactive SS Pumps with PVC leads or Geotech SS Geosub pumps for groundwater collection at depths greater than 25 feet. These pumps are stainless steel and will minimize introductions of PFCs, and have been successfully utilized at other PFC sites. If non-dedicated sampling is to be used and the contaminant histories of the wells are known, it is advisable to establish a sampling order starting with the least contaminated well and progressing to the most contaminated last. Rev. 1 3 DATE STARTED: 07/21/2014 4.2.2 Groundwater Purging and Sampling with a Bladder Pump Bladder pumps have either low density polyethylene or Teflon liners, and will not be used for PFC sampling. 4.2.3 Groundwater Purging and Sampling with a Peristaltic Pump Purging and sampling will be conducted per the project work plans. The standard procedure for groundwater purging and sampling using a peristaltic pump is in agreement with procedures described in the Compendium of Superfund Field Operations Methods (EPA, 1987) and will be conducted as described below.  Inspect the equipment to ensure that it is in good working order.  Calibrate all field analytical test equipment (e.g., pH, specific conductance, dissolved oxygen, oxidation-reduction potential, turbidity, and temperature) according to the instrument manufacturers’ specifications or scope-specific work plan. Calibration results will be recorded on the appropriate form(s) as specified by the project work plans. Instruments that cannot be calibrated according to the manufacturers’ specifications will be removed from service and tagged.  Conduct equipment decontamination; however, the old silicone tubing used in the pump head should not be decontaminated. New tubing should be used for each well.  Visually inspect the well to ensure that it is undamaged, properly labeled, and secured. Damage or other conditions that may affect the integrity of the well will be recorded on the Field Log and brought to the attention of the Field Manager.  Uncap the well and monitor the air space immediately above the open casing per the health and safety plan. Observe if any air is flowing into or out of the casing. In the event such conditions are observed, they should be noted on the Groundwater Sample Collection Form.  Obtain a static water level measurement and calculate the cased well volume. 2 d  ( ) ( h 1 - h 2 ) x 7.48 = cased well volume (in gallons) 2 Where: d = inside diameter of well casing (in feet) h1 = depth of well from top of casing (in feet) h2 = depth to water from top of casing (in feet)  Record static water level, total well depth, and volume calculations on the sample collection field sheet. Rev. 1 4 DATE STARTED: 07/21/2014  Connect new silicone tubing to the rotor head of the pump motor and tighten until snug.  Run a short section of the tubing from the discharge side of the pump head to a collection vessel.  Insert the free end of the influent tubing into the well and lower it to the middle of the well screen. The depth of the tubing intake will be recorded on the field form. For low yielding wells, it may be necessary to gently lower the tubing intake during purging to follow the declining water level in the well.  Begin and conduct purging.  Physical parameters (i.e., pH, specific conductance, dissolved oxygen, oxidation- reduction potential, turbidity and temperature) of the purge water will be measured when purging begins, after each well casing volume, and then periodically throughout the purging procedure. These measurements will be recorded on Groundwater Sample Collection Forms. Purging is considered complete when water quality indicator parameters have stabilized (i.e., three consecutive readings are within tolerances specified in Table 4-1) (ASTM, 2007; EPA, 1992 and Barcelona et al, 1985). Table 4-1 Parameter Units Requirement pH Standard Units ± 0.1 Micromhos/centimeter Specific Conductivity ± 3 percent (umho/cm, or µS/cm) Temperature Degrees Celcius (ºC) ± 0.5 oC Oxidation-Reduction Millivolts (mV) ± 10 percent Potential (ORP) Dissolved Oxygen Milligrams/liter (mg/L) ± 10 percent Nephelometric Turbidity ± 10 percent, but less than Turbidity Units (NTUs) 10 NTUs  If stability is not reached within the removal of three cased well volumes then purging is continued until a maximum of five cased well volumes have been removed. For slowly recharging wells, the parameters may not stabilize before the well casing is emptied, even when using low flow rates. In this case, purging will be considered complete when one well volume (well casing plus filter pack volume) has been purged from the well and the well goes dry. Rev. 1 5 DATE STARTED: 07/21/2014  The well will be allowed to recharge, and sampling must be initiated within 24-hours of purging. The depth to the water level in the well will be measured and recorded immediately prior to sample collection. If the volume of water in the recharged well is not sufficient to completely fill all required sample containers, then sample collection may follow multiple well recharge events within 48 hours after completion of purging. All sample containers for a given analytical method (e.g., EPA 8330) must be concurrently and completed filled following a single recharge event. If VOC analysis is required, the sample aliquot should be collected during the first sample collection event (i.e., first recharge volume). The date and time of each sample collection will be recorded.  Inspect the sampling bottles (obtained from the analytical laboratory prior to the sampling event) to be used to ensure that they are appropriate for the samples being collected, are undamaged, and have had the appropriate types and volumes of preservatives added. The types of sample containers to be used and sample preservation requirements will be provided in the project work plans.  Turn on and adjust the rotor speed of the pump so that the water will flow smoothly and without agitation into the sample bottles.  Collect the sample directly into the provided sample bottle (container), allowing the discharge to flow gently down the inside of the bottle, minimizing aeration of the sample. Completely fill the bottle; however, samples collected for metals and general water chemistry analyses should be filled to the base of the bottleneck.  The samples should be collected in the order of volatility, collecting the most volatile samples first, followed by the least volatile samples.  Document the sampling event on the Groundwater Sample Collection Form.  Appropriately seal, store, handle, and ship the samples per SOP AMEC-10. 4.2.4 Groundwater Purging and Sampling with an Electric Submersible Pump Purging and sampling will be conducted in accordance with the project work plans. The standard procedure for purging and sampling using a submersible pump is in agreement with procedures described in the Compendium of Superfund Field Operations Methods (EPA, 1987) and is described below.  Inspect the equipment to ensure that it is in good working order.  Calibrate all field analytical test equipment (e.g., pH, specific conductance, dissolved oxygen, oxidation-reduction potential, turbidity and temperature) according to the instrument manufacturers’ specifications or scope-specific work plan. Calibration results will be recorded on the appropriate form(s) as specified by the project work Rev. 1 6 DATE STARTED: 07/21/2014 plans. Instruments that cannot be calibrated according to the manufacturers’ specifications will be removed from service and tagged.  If non-dedicated equipment is being used, decontaminate the equipment as described in SOP AMEC-10. During decontamination, the equipment should again be inspected for damage and, if present, repaired or replaced with undamaged equipment.  Visually inspect the well to ensure that it is undamaged, properly labeled, and secured. Damage or other conditions that may affect the integrity of the well will be recorded on the Field Log and brought to the attention of the Field Manager.  Obtain a static water level measurement and calculate the cased well volume. 2  d ( ) ( h 1 - h 2 ) x 7.48 = cased well volume (in gallons) 2 Where: d = inside diameter of well casing (in feet) h1 = depth of well from top of casing (in feet) h2 = depth to water from top of casing (in feet)  If using non-dedicated equipment, lower the pump and associated lines into the well. The pump intake should be located near the middle of the screen interval and the depth of the pump intake will be recorded on the field form. For low yielding wells it may be necessary to gently lower the pump during purging to follow the declining water level in the well.  Place the generator downwind of the well. Start the generator, and then plug the pump into the generator.  Begin purging. Physical parameters (i.e., pH, specific conductance, dissolved oxygen, oxidation-reduction potential, turbidity, and temperature) of the purge water will be measured when purging begins, after each well casing volume, and then periodically throughout the purging procedure. These measurements will be recorded on Groundwater Sample Collection Forms. Purging is considered complete when water quality indicator parameters have stabilized (i.e., three consecutive readings are within tolerances specified in Table 4-1) (ASTM, 2007; EPA, 1992 and Barcelona et al, 1985). If stability is not reached within the removal of three cased well volumes then purging is continued until a maximum of five cased well volumes have been removed. For slowly recharging wells, the parameters may not stabilize before the well casing is emptied, even when using low flow rates. In this case, purging will be considered complete when Rev. 1 7 DATE STARTED: 07/21/2014 one well volume (well casing plus filter pack volume) has been purged from the well and the well goes dry.  The well will be allowed to recharge, and sampling must be initiated within 24-hours of purging. The depth to the water level in the well will be measured and recorded immediately prior to sample collection. If the volume of water in the recharged well is not sufficient to completely fill all required sample containers, then sample collection may follow multiple well recharge events within 48 hours after completion of purging. All sample containers for a given analytical method (e.g., EPA 8330) must be concurrently and completed filled following a single recharge event. The date and time of each sample collection will be recorded.  Inspect the sampling bottles (obtained from the analytical laboratory prior to the sampling event) to be used to ensure that they are appropriate for the samples being collected, are undamaged, and have had the appropriate types and volumes of preservatives added. The types of sample containers to be used and sample preservation requirements will be provided in the project work plans.  Turn on and adjust the flow rate of the pump by using the check-valve on the discharge line so that the water will flow smoothly and without agitation into the sample bottles.  Collect the sample directly into the provided sample bottle (container), allowing the discharge to flow gently down the inside of the bottle, minimizing aeration of the sample. Completely fill the bottle; however, samples collected for metals and general water chemistry analyses should be filled to the base of the bottleneck.  Document the sampling event on the Groundwater Sample Collection Form.  Appropriately seal, store, handle and ship the samples per SOP AMEC-11. 4.2.5 Groundwater Purging and Sampling with a Bailer Purging and sampling will be conducted in accordance with the project work plans. The standard procedure for purging and sampling with a bailer is in agreement with procedures described in the Compendium of Superfund Field Operations Methods (EPA, 1987) and is described below. (Note: bailers containing Teflon or LDPE will not be utilized for PFC sampling.)  Inspect the equipment to ensure that it is in good working order.  Calibrate all field analytical test equipment (e.g., pH, specific conductance, dissolved oxygen, oxidation-reduction potential, turbidity and temperature) according to the instrument manufacturers’ specifications or scope-specific work plan. Calibration results will be recorded on the appropriate form(s) as specified by the project work plans. Instruments that cannot be calibrated according to the manufacturers’ specifications will be removed from service and tagged. Rev. 1 8 DATE STARTED: 07/21/2014  Decontaminate purging and sampling equipment.  Visually inspect the well to ensure that it is undamaged, properly labeled, and secured. Damage or other conditions that may affect the integrity of the well will be recorded on the Field Activity Daily Log and brought to the attention of the Field Manager.  Obtain a static water level measurement and calculate the cased well volume.  Secure the bailer to a five foot length of stainless bailer wire with a bowline knot or clip. Attach the bailer wire to bailing line or chain.  Begin purging by slowly lowering the bailer into the groundwater. Allow the floating ball valve to seat, and slowly retrieve the bailer. Repeat this procedure to purge the well. Collect, transport, and dispose of purge water in accordance with the criteria specified in the project work plans.  During purging, the descent of the bailer should be controlled to prevent freefall inside the well. In the event the bailer encounters an obstruction inside the well, no attempts may be made to push the bailer beyond the obstruction. If the bailer becomes lodged in the well, the line should not be pulled with such force that it would part from the bailer. Such conditions should also be noted in the Field Log and brought to the immediate attention of the Field Manager.  The well will be allowed to recharge, and sampling must be initiated within 24-hours of purging. The depth to the water level in the well will be measured and recorded immediately prior to sample collection. If the volume of water in the recharged well is not sufficient to completely fill all required sample containers, then sample collection may follow multiple well recharge events within 48 hours after completion of purging. All sample containers for a given analytical method (e.g., EPA 8330) must be concurrently and completed filled following a single recharge event. The date and time of each sample collection will be recorded.  Inspect the sampling bottles (obtained from the analytical laboratory prior to the sampling event) to be used to ensure that they are appropriate for the samples being collected, are undamaged, and have had the appropriate types and volumes of preservatives added. The types of sample containers to be used and sample preservation requirements will be provided in the project work plans.  Lower the sample collection bailer and submerge into the water column as above. Retrieve the bailer and insert a bottom-emptying device into the bailer so that the water will flow smoothly and without agitation into the sample bottles.  Collect the sample water directly into the provided sample bottles (containers), allowing the discharge to flow gently down the inside of the bottles, minimizing aeration of the Rev. 1 9 DATE STARTED: 07/21/2014 sample. Completely fill the bottles; however, samples collected for metals and general water chemistry analyses should be filled to the base of the bottleneck.  Document the sampling event on the Groundwater Sample Collection Form.  Appropriately seal, store, handle, and ship the samples per SOP AMEC-11. Rev. 1 10 DATE STARTED: 07/21/2014 MONITORING WELL INSTALLATION SOP AMEC-04 (PFCs) 1.0 PURPOSE This Standard Operating Procedure (SOP) provides procedures and requirements for the installation of monitoring wells using various drilling techniques, including but not limited to, direct push technology (DPT), hollow-stem auger (HSA), rotary, sonic or dual-tube percussion for the assessment of PFC compounds in groundwater. The details within this SOP should be used in conjunction with specific project work plans. 2.0 REFERENCES ASTM International (ASTM), 2010 Standard Guide for Installation of Direct Push Ground Water monitoring Wells, Method D-6724-04 ASTM International (ASTM), 2010 Standard Practice for Design and Installation of Groundwater Monitoring Wells, Method D-5092-04 ASTM International (ASTM), Standard Guide for the Use of Hollow Stem Auger Drilling for Geoenvironmental Exploration and Installation of Subsurface Monitoring Devices, Method D5784/5784M-13 ASTM International (ASTM, 2012 Standard Guide for the Use of Direct Air Rotary Drilling for Geoenvironmental Exploration and Installation of Subsurface Monitoring Devices, Method D5782-95 ASTM International (ASTM), Standard Guide for the Use of Dual Wall Reverse Circulation Drilling for Geoenvironmental Exploration and Installation of Subsurface Monitoring Devices, Method D5781/5781M-13 ASTM International (ASTM), Standard Guide for the Use of Casing Advancement Drilling Methods for Geoenvironmental Exploration and Installation of Subsurface Monitoring Devices, Method D5872/5872M-13 U.S. Environmental Protection Agency (EPA), 1986, Resource Conservation and Recovery Act (RCRA) Ground Water Monitoring Technical Enforcement Guidance Document, OSWER- 9950.1, U.S. Environmental Protection Agency, Office of Solid Waste and Emergency Response, U.S. Government Printing Office, Washington D.C.

Rev. 1 1 DATE STARTED: 07/21/2014 3.0 DEFINITIONS Cuttings – Pieces of soil, sediment, or rock cut by a bit in the process of drilling borings. Borehole – Any hole drilled into the subsurface for the purpose of identifying lithology, collecting soil samples, and/or installing groundwater wells. Grout – For the purposes of this SOP, the term “grout” consists of a neat cement grout generally containing one 94 pound bag of Portland cement mixed with clean water and bentonite. The grout is emplaced as a slurry, and once properly set and cured, is capable of restricting movement of water. Direct Push Drilling – For the purposes of this monitoring well installation SOP, the term “direct push drilling” refers to using DPT to push or drive hollow rods into the ground for the purpose of installing monitoring wells with a maximum inside diameter of 1 inch when using 2.625 inch inside diameter DPT rods. Direct push drilling uses an expendable drive point that is fitted to the lower end of a string of drive rods that are advanced into the ground using percussive hammering. No cuttings are brought to the surface during drilling, although soil cores may be retrieved using various sampling tools. Hollow-Stem Auger Drilling – A drilling method using augers with open centers. The augers are advanced with a screwing or rotating motion into the ground. Cuttings are brought to the surface by the rotating action of the augers, thereby clearing the borehole. Air Rotary Casing Hammer Drilling – A drilling method using a non-rotating drive casing that is advanced simultaneously with a slightly smaller diameter rotary bit attached to a string of drill pipe. The drive casing is a heavy-walled, threaded pipe that allows for pass-through of the rotary drill bit inside the center of the casing. Air is forced down through the center drill pipe to the bit, and then upward through the space between the drive casing and the drill pipe. The upward return stream removes cuttings from the bottom of the borehole. Mud Rotary Drilling – For the purposes of this monitoring well installation SOP, the term “mud rotary drilling” refers to direct circulation (as opposed to reverse circulation) mud rotary drilling. Mud rotary drilling uses a rotating drill bit which is attached to the lower end of a string of drill pipe. Drilling mud is pumped down through the inside of the drill pipe and out through the bit. The mud then flows upward in the annular space between the borehole and the drill pipe, carrying the cuttings in suspension to the surface. Dual-Tube Percussion Drilling – A drilling method using non-rotating drive casing with a bit on the bottom of the casing string. A smaller diameter tube or drill pipe is positioned inside the drive casing. The drive casing is advanced by the use of a percussion hammer, thereby causing the bit to cut or break up the sediment or soil at the bottom of the boring. Air is forced down Rev. 1 2 DATE STARTED: 07/21/2014 the annular space between the drive casing and inner drill pipe and cuttings are forced up the center of the inner drill pipe. Sonic Drilling – Sonic drilling is a drilling technique that incorporates the use of high frequency vibrations to facilitate the drilling process. Sonic drills can penetrate very quickly and cope with a wide variety of substrates and formations. For core sampling, sonic drilling can be a highly effective tool allowing for the collection of very large continuous core samples. Monitoring Well – A well that provides for the collection of representative groundwater samples, (including the detection and collection of representative light and dense non-aqueous phase organic liquids), and the measurement of fluid levels. Annular Space – The space between:  Concentric drill pipes;  An inner drill pipe and outer drive casing;  Drill pipe or drive casing and the borehole wall; or,  Well screen or casing and the borehole wall. Filter Pack – Granular filter material (sand, gravel, etc.) placed in the annular space between the well screen and the borehole to increase the effective diameter of the well and prevent fine-grained material from entering the well. Well Screen – A commercially available, factory-perforated, wire wound, continuous wrap, or slotted casing segment used in a well to maximize the entry of water from the producing zone and to minimize the entrance of sand. Tremie – A tubular device or pipe used to place grout, bentonite, or filter pack in the annular space. 4.0 PROCEDURE This section contains both main responsibilities and procedures for monitoring well installation activities. The procedures described herein are applicable as requirements for monitoring well installations using DPT, HSA, mud rotary, air rotary, air rotary casing hammer, sonic, or dual tube percussion drilling techniques. Site-specific factors need to be considered in the selection of well construction and completion materials, specification of well designs, and choosing well drilling methods. These factors will be incorporated in project planning activities and the compilation of specific project work plans. The project work plans will contain the following information related to monitoring well installation:  Objectives of the monitoring well;  Specific location of the well to be installed; Rev. 1 3 DATE STARTED: 07/21/2014  Zone or depth well is to be installed;  Drilling method(s) to be used;  Well construction materials to be used;  Specification of well design(s) including Well Construction Diagrams; and,  Additional procedures or requirements beyond this SOP. 4.1 RESPONSIBILITIES Project Manager The Project Manager is responsible for ensuring that all monitoring well installation activities are conducted and documented in accordance with this and any other appropriate procedures. This will be accomplished through staff training and by quality assurance/quality control (QA/QC) monitoring activities. Field Manager The Field Manager is responsible for periodic observation of well installation activities to assure implementation of this SOP. The Field Manager is also responsible for the review and approval of corrective action (i.e., retraining personnel, additional review of work plans and SOPs, variances to monitoring well installation requirements, issuing nonconformances, etc.) identified during the performance of these activities. Field Personnel Field personnel assigned to monitoring well installation activities are responsible for completing their tasks according to specifications outlined in this SOP and other appropriate procedures. Field staff are responsible for reporting deviations from the procedures to the Project Manager or the Field Manager. 4.2 WELL INSTALLATION PROCEDURES Before mobilization of a rig to the well site, ensure that the monitoring well location has been appropriately cleared of all underground utilities and buried objects, and that drill permits have been issued per the project work plans. Review all forms and diagrams documenting the location of the cleared monitoring well site and the location of any identified underground utility lines or other buried objects. All water used for decontamination, boring completion, and well installation shall be PFC free or from municipal supply. Decontaminate down-hole equipment and well construction materials before monitoring well installation. Decontaminate the drilling rig and all drilling equipment before monitoring well installation. Rev. 1 4 DATE STARTED: 07/21/2014 Clear the work site of brush and minor obstructions and then mobilize the rig to the monitoring well location. The rig geologist or engineer should then review with the driller the proposed well design and details of the well installation including any potential drilling or completion problems. Calibrate field equipment according to the instrument manufacturer’s specifications. Document the calibration results on the appropriate form(s). Instruments that cannot be calibrated according to the manufacturer’s specifications will be removed from service and tagged. Workers will be provided with, and don, the appropriate personal protective equipment as specified by the project work plans. Typically, the minimum personal protection will include a hard hat, safety glasses, gloves and steel-toed boots. Commence drilling and advance the borehole while conducting health and safety monitoring according to the project work plans. Perform readings as often as necessary to ensure the safety of workers. Record all measurements in the field log and/or other appropriate form(s) as specified in the project work plans. Record other pertinent information (date, site, well or boring number, and location) in the field log and/or on other appropriate form(s) as specified by the project work plans. In addition, note and record observed field conditions, any unusual circumstances, and weather conditions. During drilling, collect representative cutting and soil samples as required by the project work plans. Compile a boring log or lithologic log from the cuttings and samples (see SOP AMEC-02 Soil Sampling). At total depth, remove soil cuttings through circulation or rapidly spinning the augers prior to constructing the well (as applicable to site conditions). Review logs and notes with the driller for any zones or depths exhibiting drilling problems that may affect the well installation. Condition the hole or take other actions mutually agreed upon by the rig geologist (or engineer), lead technical personnel, and the driller to ensure or aid in the well development. Remove the drill pipe and bit if using rotary techniques, or remove the center bit boring if using the hollow-stem auger technique, or disengage the expendable drive point if using DPT. The well construction materials will then be installed inside the open borehole or through the center of the drive casing, or augers. Measure the total depth of the completed boring using a weighted sounding line. The borehole depth is checked to assure that formation material has not heaved to fill the borehole. If heaving has taken place, options for cleaning, re-drilling, or installation in the open section of the boring should be discussed with lead technical personnel. Rev. 1 5 DATE STARTED: 07/21/2014 In the event that the hole was over-drilled, bentonite pellets, or bentonite chips (as specified in the project work plans) may be added to the bottom of the boring to raise the bottom of the hole to the desired depth. The bentonite should be pumped through a tremie pipe and fill from the bottom of the boring upward. During pumping of bentonite slurry, the tremie pipe should be submerged below the top of the bentonite column in the borehole to prevent free-fall and bridging. If bentonite chips or pellets are used, it should be added gradually to prevent bridging. Bentonite addition will stop when its level has reached approximately one foot below the desired base of the well string (casing, screen, end plug or sump, etc.). The bentonite plug will be hydrated for at least one hour before installation of a filter pack. Calculate volumes of filter pack, bentonite pellets/slurry, and grout required, based on borehole and well casing dimensions. If required by the project work plans, determine the filter pack and well screen slot size for the monitoring well. For most monitoring well installations, the filter pack and well screen slot size will be determined prior to the start of the installation activities (typically 10 slot screen and 20/40 sieve sands). Inspect the casing, screen, and any other well construction materials prior to installation to assure that no damage has occurred during shipment and decontamination activities. Connect and carefully lower the well string through the open borehole, drive rods or casing, or inside of the augers until the well string is at the desired depth. The well string should be suspended by the installation rig and should not rest on the bottom of the boring. In the event the well string was dropped, lowered abruptly, or for any other reason suspected of being damaged during placement, the string should be removed from the boring and inspected. In certain instances, the well string may rise after being placed in the borehole due to heaving sands. If this occurs, the driller must not place any drilling equipment (drill pipe, hammers, etc.) to prevent the casing from rising. The amount of rise should be noted by the rig geologist or engineer who should then consult lead technical personnel for an appropriate course of action. Record the following information on the appropriate forms per the project work plans:  Length of well screen;  Total depth of well boring;  Depth from ground surface to top of grout or bentonite plug in bottom of borehole (if present);  Depth to base of well string; and,  Depth to top and bottom of well screen. When using the mud rotary drilling technique, tremie the filter pack into the annular space around the screen. Clean, potable water may be used to assist with the filter pack tremie Rev. 1 6 DATE STARTED: 07/21/2014 operation. For all other drilling techniques, the filter pack may be allowed to free fall or be tremied per the project work plans. If using DPT rods, drive casing, or augers, the drive rods, casing, or augers should be pulled slowly during filter pack installation in increments no greater than 5 feet. For DPT-installed wells, a pre-pack filter may be attached to or fitted around the screen and placed concurrently with the well string. Filter pack settlement should be monitored by initially measuring the sand level (before beginning to withdraw the drive casing/augers). In addition, depth soundings using a weighted tape shall be taken repeatedly to continually monitor the level of the sand. The top of the well casing shall also be monitored to detect any movement due to settlement or from drive casing/auger removal. If the top of the well casing moves upwards at any time during the well installation process, the driller should not be allowed to set drilling equipment (downhole hammers, drill pipe, etc.) on the top of the casing to prevent further movement. Filter pack should be added until its height is approximately 2 feet above the top of the screen (unless otherwise specified in the project work plans), and verification of its placement (by sounding) should be conducted. The filter pack should then be gently surged using a surge block or swab in order to settle the pack material and reduce the possibility of bridging. The height of the filter pack will then be re-sounded and additional filter pack placed as necessary. Once the placement of the filter pack is completed, the depth to the top of the pack is measured and recorded on the appropriate forms per the project work plans. A three-foot thick (unless otherwise specified in the project work plans) bentonite seal is then installed on top of the filter pack. If pellets or chips are used, they should be added gradually to avoid bridging. Repeated depth readings will be taken using a weighted tape to ascertain the top of the bentonite seal. Granular bentonite must be used if the seal is placed above the water table. After hydration of the bentonite seal, neat cement grout (mixture consisting of approximately 9 gallons of water and 94 pounds of Portland cement with bentonite to aid seal, is then pumped through a side-discharging tremie pipe and filled from the top of the bentonite seal upward. The bottom of the tremie pipe should be maintained below the top of the grout to prevent free fall and bridging. When using drive casing or hollow-stem auger techniques, the drive casing/augers should be raised in incremental intervals, keeping the bottom of the drive casing/augers below the top of the grout. Grouting will cease when the grout level has risen to within approximately one to 2 feet of the ground surface. Grout levels should be monitored to assure that grout taken into the formation is replaced by additional grout. If settling of the grout occurs, additional topping off of the grout may be necessary. Rev. 1 7 DATE STARTED: 07/21/2014 After the protective casing has set, a drainage hole may be drilled into the protective casing if required by the project work plans. The drainage hole is positioned approximately 2 inches above ground surface. The protective casing will be painted with a rust-preventive colored paint. The well head will be labeled to identify, at a minimum, the well number, depth, and date of installation. A minimum of 24 hours after grouting should elapse before installation of the concrete pad and street boxes or vaults for flush mount completions. For flush mount (or subgrade) completions, a street box or vault is set and cemented in position. The top of the street box or vault will be raised slightly above grade and the cement sloped to grade to promote surface drainage away from the well. Following well completion and demobilization of the rig, the well site should be cleared of all debris and trash and restored to a neat and clean appearance per the project work plans. All investigation-derived waste (IDW) generated at the well site should be appropriately contained and managed per the project work plans. Rev. 1 8 DATE STARTED: 07/21/2014 MONITORING WELL DEVELOPMENT SOP AMEC-05 (PFCs) 1.0 Purpose This Standard Operating Procedure (SOP) establishes general guidelines for developing groundwater monitoring wells to support perfluorinated compound (PFC) sampling. Additional site-specific well development procedures and requirements may be provided in the project work plans. 2.0 Definitions Well Development – The act of removing fine grained sediment and drilling fluids from the filter pack and formation in the immediate vicinity of the well, thus increasing the porosity and permeability of the materials surrounding the intake portion of the well. 3.0 Procedure 3.1 General The most common methods used to develop monitoring wells consist of surging and bailing, surging and pumping, or combinations of these processes. The project work plans will identify the specific well development procedure to be followed. The standard procedure for field personnel to use in assessing and documenting well development is described below and is intended only for development methods listed above. 3.2 Responsibilities Project Manager The Project Manager is responsible for ensuring that monitoring wells are properly developed and that the development process is properly documented. This will be accomplished by staff training and by maintaining quality assurance/quality control (QA/QC). Field Manager The Field Manager is responsible for periodic inspections and review of field generated documentation associated with well development. If deviations from project requirements occur, the Field Manager is also responsible for issuing nonconformance reports and requests for corrective action. Rev. 1 1 DATE STARTED: 07/21/2014 Field Personnel Field personnel are responsible for conducting monitoring well development and documentation in accordance with the specifications outlined in this SOP and by the project work plans. 3.3 Well Development Decontaminate the rig and development equipment as defined in AMEC SOP-10. For a newly installed monitoring well, allow the grout to cure for a maximum of 24 hours prior to development. Calibrate all field analytical test equipment (pH, temperature, conductivity, oxidation and reduction potential, and turbidity) according to the instrument manufacturer’s specifications and the project-specific work plan or sampling and analysis plan. Specific test equipment to be used should be identified in the project-specific work plans. Instruments that cannot be calibrated according to the manufacturer’s specifications will be removed from service, tagged with an out of calibration label, and segregated (when possible) from the calibrated equipment area. An exception to the daily calibration requirements will be made in the case of the water level meters. The tape of these instruments will be checked prior to the beginning of the project and each succeeding six months using a steel surveyor’s tape. Visually inspect the well to ensure that it is undamaged, properly labeled and secured. Any observed problems with the well head should be noted in the field log and reported to the Field Manager. Unlock the well and obtain a depth to water level measurement. Calculate the volume of water in the well (cased well volume) as follows: 2    d   h  h  .7 48   gallons per cased well volume  1 2  2  Where: d = inside diameter of well casing, ft h1 = depth of well from top of casing, ft h2 = depth to water from top of casing, ft. The depth to the bottom of the well should be measured and then compared to the completion form or diagram for the well. If sand or sediment is present inside the well, it should first be Rev. 1 2 DATE STARTED: 07/21/2014 removed by bailing. Only a PFC free bailer such as a stainless stell reusable bailer shall be used for well development purposes. Do not insert bailers, pumps, or surge blocks into the well if obstructions, parting of the casing, or other damage to the well is suspected. Report such conditions to the Field Manager and obtain approval to continue or cease well development activities. Begin development by first gently surging (ensure that no Teflon tape or other PFC laden material is included with the surging materials), followed by bailing or pumping. Only PFC free bailers (no Teflon or LDPE materials) will be permitted for bailing operations AMEC will use peristaltic pumps for groundwater sample collection at depths shallower than 25 feet. AMEC will use Proactive SS Pumps with PVC leads or Geotech SS Geosub pumps for groundwater sample collection at depths greater than 25 feet. These pumps are stainless steel and will minimize introductions of PFCs. Pumps should not be utilized until sediments are removed from the well, as free sediments can foul and damage the pump systems. Development is then continued with alternate surging and bailing or pumping. At no time should the surge block be forced down the well if excessive resistance is encountered. During development, the bailer should not be allowed to free-fall or descend rapidly such that it becomes lodged in the casing or damages the end cap or sediment trap at the bottom of the well. Use of a surge block is typically though not always required in the development of a well, particularly small diameter wells (i.e., 2 inches or less). Document well development direction that would vary from surge block usage in the field log. While developing the well, periodic water level measurements (at least one every five minutes) will be made to determine drawdown. Water level measurements and pump rates as well as volumes removed should be recorded on the well development record. If a well is pumped to dryness, then development will cease and not resume until the water level in the well recovers to approximately 80 percent of static aquifer conditions. While developing, water samples are periodically collected and readings taken of the indicator parameters: pH, specific conductance, oxidation/reduction potential, dissolved oxygen, turbidity, and temperature. Development is considered complete when the indicator parameters have stabilized (i.e., three consecutive pH, specific conductance, and temperature readings are within tolerances specified in the project work plans or within 10% if not otherwise specified) and the maximum turbidity is 50 nephelometric turbidity units (NTUs) or less, or the well develops dry. Rev. 1 3 DATE STARTED: 07/21/2014 Parameter Units Requirement pH Standard Units ± 10 percent Micromhos/centimeter Specific Conductivity ± 10 percent (umho/cm, or µS/cm) Temperature Degrees Celcius (ºC) ± 0.5 oC Oxidation-Reduction Millivolts (mV) ± 10 percent Potential (ORP) Dissolved Oxygen Milligrams/liter (mg/L) ± 10 percent Nephelometric Turbidity Turbidity Maximum of 50 NTUs Units (NTUs) At minimum three times the amount of water used but not recovered during drilling and well installation activities will be removed during development operations. In certain instances, for slow recharging wells or small-diameter wells, the parameters may not stabilize. In this case, well development is considered complete upon the removal of three times the amount of water used during drilling and well installation activities (if used) and when the best achievable water quality has been attained (i.e. no further improvement observed) using a combination of surging and pumping as described above. Obtain a water level and turbidity measurement at the completion of development. Complete documentation of the well development event on the well development form. At a minimum this record must contain:  Project name and number;  Location ID;  Well identification number;  Well depth, casing size, and completion date;  Method of development;  Volume of water removed;  Water levels (including the time of measurement);  Physical description of the water (e.g., discoloration, turbidity, odor, etc.) and solids removed from the well; Rev. 1 4 DATE STARTED: 07/21/2014  Test equipment readings for pH, conductivity, temperature and turbidity (including the time of collection); and,  Signature of the well development observer. Collect and appropriately dispose of water removed from the well in accordance with criteria listed in the project-specific work plans and regulatory requirements. Allow the well to recover for at least 24 hours prior to sampling. 3.4 Well Re-Development For redevelopment of existing monitoring wells to be used in the analyses for PFC constituents the well will be developed as if it were a new well (as addressed in 3.3 above). Evaluation of current and historical site conditions if know shall be recorded in the field log. Data including but not limited to the following shall be recorded on redeveloped wells:  Well construction information o Depth o Water level o Filter pack o Screen zone o Flow rate if known o Etc  Sampling equipment left in well including types  Date of last sampling event if known  Materials with known PFC constituents found at the site or in contact with the water.  State the well was left in following our sampling – i.e. all dedicated materials returned to well unless otherwise directed by client. Rev. 1 5 DATE STARTED: 07/21/2014 BOREHOLE ABANDONMENT SOP AMEC-06 (PFCs) 1.0 PURPOSE This Standard Operating Procedure (SOP) establishes guidelines and procedures for field personnel to use in the supervision of borehole or soil boring abandonment and groundwater monitoring well abandonment activities. Additional specific borehole and well abandonment procedures and requirements will be provided in the project work plans. 2.0 DEFINITIONS Borehole Abandonment – The process whereby boreholes or soil borings are grouted or sealed following completion of drilling, sampling and/or logging. 3.0 PROCEDURE This section contains responsibilities, procedures and requirements for borehole abandonment. Abandonment procedures to be used at a particular site must incorporate project-specific regulatory requirements. Consequently, the project work plans will identify the following:  Abandonment objectives,  Boreholes to be abandoned,  Specific procedures for borehole abandonment beyond those covered in this SOP; and,  Applicable site-specific regulatory requirements for borehole abandonment. 3.1 Responsibilities Project Manager The Project Manager is responsible for ensuring that all abandonment activities are conducted and documented in accordance with this SOP and any other appropriate procedures. This will be accomplished through staff training and by maintaining quality assurance/quality control (QA/QC). Field Manager The Field Manager is responsible for periodically observing field activities and review of field generated documentation associated with this SOP. The Field Manger is also responsible for the implementation of corrective action (i.e., retraining personnel, additional review of work plans and SOPs, variances to the abandonment requirements, issuing nonconformances, etc.) if problems occur. Rev. 1 1 DATE STARTED: 07/21/2014 Field Personnel Field personnel assigned to borehole and well abandonment activities are responsible for completing their tasks according to specifications outlined in this SOP and other appropriate procedures. All staff are responsible for reporting deviations from the procedures to the Project Manager or Field Manager. 3.2 Abandonment of Boreholes After drilling, logging and/or sampling, boreholes should be backfilled by the method required by the applicable agency and described in the project work plans. This typically consists of backfilling to the surface with bentonite chips, pellets or bentonite-cement grout. If bentonite chips or pellets are used, they should be added to the borehole in two foot lifts and hydrated with water from a potable water supply. This process should be repeated until the entire borehole is plugged using no less than five gallons water per ten feet of borehole. If bentonite grout is used the following guidelines should be followed:  Bentonite should be thoroughly mixed into the grout and within the percentage range specified in the work plans. If not otherwise specified in the work plans, the cement- bentonite grout mixture should be of the following proportions: 94 pounds of Portland cement, 5 pounds of powdered bentonite and a maximum of 8 gallons of water. The grout is usually tremied into the hole; however, for selected boreholes (e.g., shallow borings well above the water table) at certain sites, the grout may be allowed to free fall. In either case, care must be taken to ensure the grout does not bridge, forming gaps or voids in the grout column.  The volume of the borehole should be calculated and compared to the grout volume used during grouting to aid in verifying that bridging did not occur.  When using a tremie to place grout in the borehole, the bottom of the tremie should be submerged into the grout column and withdrawn slowly as the hole fills with grout. If allowing the grout to free fall (and not using a tremie), the grout should be poured slowly into the boring. The rise of the grout column should also be visually monitored or sounded with a weighted tape.  If the method used to drill the boring utilized a drive casing, the casing should be slowly extracted during grouting such that the bottom of the casing does not come above the top of the grout column.  During the grouting process, the drilling hands performing the task should be supervised to assure that potentially contaminating material (oil, grease, or fuels from gloves, pumps, hoses, et. al) does not enter the grout mix and that personnel are properly Rev. 1 2 DATE STARTED: 07/21/2014 wearing personal protective equipment as specified in the project Health and Safety Plan.  Following grouting, barriers should be placed over grouted boreholes as the grout is likely to settle in time, creating a physical hazard. Grouted boreholes will typically require at least a second visit to “top off” the hole.  The surface hole condition should match the pre-drilling condition (asphalt, concrete, or smoothed flush with native surface), unless otherwise specified in the project work plans. Rev. 1 3 DATE STARTED: 07/21/2014 SEDIMENT SAMPLING SOP AMEC-07 (PFCs) 1.0 PURPOSE This Standard Operating Procedure (SOP) establishes guidelines and procedures for use by field personnel in the collection and documentation of sediment samples for chemical and physical analysis. This SOP does not include the procedures and equipment selection for sediment sampling for biological analysis, which is very specific to the aquatic environment and type of analysis (toxicological and bioaccumulation tests, benthic community analysis, etc.), and would be covered in the project work plan. This SOP is only applicable to bedload sediment sampling, and does not include suspended load sampling. 2.0 REFERENCES American Society for Testing and Materials (ASTM), 1995, Standard Guide for Core Sampling Submerged, Unconsolidated Sediments, ASTM D 4823-95, reapproved October 1, 2008.

Broadly speaking, sediment is “eroded material which lies below surface water the majority of the time where the surface water is capable of providing for an aquatic biota habitat.” Bedload sediment lies on top of, and is transported along, the surface of the channel or basin floor, that can be comprised of soil or bedrock. The inorganic particles of sediment range from clay to gravel size. Rev. 1 1 DATE STARTED: 07/21/2014 Many contaminants in sediment are trapped in the interstitial water, while other contaminants are adsorbed onto the organic matter. Therefore, coarse sand- to gravel-size sediment is usually not a good candidate sample for chemical analysis, as the water and organic content is usually low. Sediment Sample – Environmental samples of sediment can be collected as a single grab sample or as a composite sample from the top 6 inches of sediment material. Surficial grab samples (single or composited) are preferred when the source of contamination is recent or the sedimentation rate is low, the surface water is known to have been a contaminant migration pathway, and the horizontal distribution of the contamination is being assessed. Vertical profile samples will not be collected for this project. Disturbed Sediment Sample – A sediment sample whose in situ physical structure and fabric has been disturbed as the direct result of sample collection. Disturbed sediment samples can be collected using hand augers, spoons, or scoops as described in Section 4.2. Undisturbed Sediment Sample – A sediment sample whose in situ physical structure and fabric has not been disturbed as the result of sample collection. Undisturbed sediment samples can be collected using the core samplers described in Section 4.2. Grab Samples – A disturbed sediment sample that is collected by using such devices as the sample container (e.g., wide-mouth jar), or a stainless steel spoon, scoop, or hand auger, and is representative of the current conditions at the location sampled. Composite Samples – Composite samples are comprised from at least two grab samples that are thoroughly mixed in a decontaminated bowl to be representative of an area, transect, or vertical section. The result typically is considered an average concentration of the area or column of sediment sampled. 4.0 PROCEDURE This section contains both the responsibilities and procedures involved with sediment sampling. Proper sediment sampling procedures are necessary to insure the quality and integrity of the samples. The details within this SOP should be used in conjunction with installation-specific work plans. The installation-specific work plans will generally provide the following information:  Sample collection objectives;  Approximate locations and depths of sediment samples to be collected;  Numbers and volumes of sediment samples to be collected;  Types of analyses to be conducted for the samples; Rev. 1 2 DATE STARTED: 07/21/2014  Specific quality control procedures required; and,  Any additional sediment sampling requirements or procedures beyond those covered in this SOP, as necessary. The text below describes the general procedures for sediment sampling. 4.1 RESPONSIBILITIES Project Manager The Project Manager is responsible for ensuring that all sample collection activities are conducted in accordance with this SOP and any other appropriate procedures. This will be accomplished through staff training and by maintaining quality assurance/quality control. Field Manager The Field Manager is responsible for observing sampling activities and periodic review of field generated documentation. The Field Manager is responsible for implementation of corrective action (i.e., retraining personnel, additional review of work plans and SOPs, variances to quality control sampling requirements, issuing nonconformances, etc.) if problems occur. Field Personnel Field personnel assigned to sediment sampling activities are responsible for completing their tasks according to specifications outlined in this SOP and other appropriate procedures. All staff members are responsible for reporting deviations from procedures to the Field Manager. 4.2 SEDIMENT SAMPLING EQUIPMENT A number of devices are available for the collection of sediment samples, the proper selection of which is dependent on the sampling objectives, whether the sediment is above or below water, the sediment thickness, the depth of water above the sediment, the accessibility and conditions of the sampling locations, and the analytical requirements. Therefore, it is prudent to conduct a site visit of the sampling locations before the development of the work plan. Two types of sediment sampling devices will typically be used: core samplers and grab samplers. Most of these devices are constructed of stainless steel, and some core samplers allow a sleeve (should be made of high density polyethylene [HDPE] or acetate – Teflon or low density polyethylene (LDPE) should not be used) to be inserted into the core barrel to retain the sample. Rev. 1 3 DATE STARTED: 07/21/2014 Core Samplers The collection of submerged sediment samples and most sediment deposits above water, both grab and composite samples, may be conducted with a core sampler. The advantage of a core sampler over a grab sampler is that discrete and less disturbed samples can be collected if needed and there is no loss of fines as the sample is raised to the surface (ASTM, 2008). The simplest core sampler is a hand-driven, hollow, stainless steel or polycarbonate core barrel, with a beveled edge on the head assembly at the leading end and a check valve or flapper valve at the opposite end to keep the sample in the barrel by partial vacuum (end-filling type). The trailing end has a T-handle to push and/or twist the core barrel into the soft sediment. Core barrels are typically 1- to 2-inches in diameter and are available in 2- and 4-foot lengths. For deeper submerged sediments (> 2 feet), usually collected from a boat, handle extensions can be added to the top of the hand core sampler. For this project it is anticipated that all sediment samples will be collected from 0 to 6 inches deep. A sample sleeve, or core liner can be inserted into some core samplers to obtain discrete samples that are handled and shipped in the sleeve. Upon extrusion from the core barrel, cores can be subsampled or homogenized. One disadvantage to core samplers is that the volume of sediment retrieved in one core barrel may be insufficient if full suites of analyses are needed, thus requiring multiple cores to be collected at each location. All sample sleeves or core liners shall be comprised of a PFC free material and approved prior to use. Grab Samplers Grab samplers will disturb the sediment during collection, which may be a limiting factor for some sampling parameters and objectives. If sampling dry to moist surficial sediments is the sampling objective, then a sample can be collected by using grab samplers such as stainless steel hand augers, spoons, or scoops, or the sample containers themselves. If sampling shallow submerged sediment (< 6 inches deep), then the sample container may be used as the preferred collection device to minimize loss of fines upon raising the sample to the surface. The lid of the sample container may be used to cover the mouth of the sample container before raising it to the surface. For deeper submerged sediments (> 2 feet), usually collected from a boat, a Ponar grab sampler or equivalent is an option for surficial deposits. This type of sampler has a jaw-type mechanism that is tripped from above in order to close the jaws and collect the sample. The dredge is lowered slowly through the water to the sediment with the jaws in the open position. As the dredge is retrieved, the jaws close and the isolated sediment is brought to the surface. The Rev. 1 4 DATE STARTED: 07/21/2014 disadvantage to using these grab samplers is that a pebble or stick can often prevent the jaws from shutting completely, and the sample will be washed or lost upon raising the sampler to the surface. If sample collection is not successful using a grab sampler, then use of a core sampler may be required. 4.3 SEDIMENT SAMPLE COLLECTION Pre-Sample Planning  Review carefully the Health and Safety Plan (HSP) and/or the Hazard Assessment.  If current information is not available, conduct a reconnaissance of all sediment sampling locations to determine accessibility to the water body, depth of water, dangerous conditions (strong currents, boggy bottoms, log jams or beaver dams, waterfalls, steep banks, thick vegetation, etc.), sediment accumulation points to flag for sampling (pools, convex side of meanders, mid-channel islands, downstream side of boulders, deltas, etc.), and sampling and personal protection equipment selection criteria. Access to water bodies such as streams may be hampered by thick vegetation, and lakes and ponds that will require the use of a boat may not be accessible by road. Therefore, the logistics of getting the sampling equipment and containers to and from the sites must be considered before attempting to sample.  The timing of sediment sampling relative to stream flow is critical, even when fluctuation in stream flow is not a variable of concern in the project objectives. Avoid sampling during high water or flood conditions, not only for safety reasons, but also because most sediment deposits will be submerged under deeper water, will be eroding due to turbulent flow, and will be migrating and/or in suspension. If the same locations are being sampled on a periodic basis (e.g., quarterly, semi-annually, yearly), it is critical to sample under the same flow conditions (e.g., base flow) each time.  Plan to collect sediment (and co-located surface water) samples along a water body in the upstream direction, starting from the most downstream sampling location. This procedure will insure that any mobilized contaminants or fine particles from sampling activities, which will migrate downstream, do not affect the representativeness of the subsequent samples. This procedure must be followed even in lakes or ponds that are stream fed.  Select biased locations where sediment occurs. Transects may have to be diagonal to stream flow instead of perpendicular to include point bars on opposite sides. For establishing a grid or transects in a lake, placing buoys at the nodes/sampling locations works well. At small ponds, transects can be marked by stretching a cord or cable Rev. 1 5 DATE STARTED: 07/21/2014 between stakes on opposing shores, using turn-buckles to provide tauntness and flagging tape to mark sampling locations.  If accessing and reaching the sampling locations is difficult, taking a portable global positioning system (GPS) instrument to obtain X-Y coordinates during sampling is recommended, to avoid repeating trips. Such difficult locations will be costly to land survey. If a GPS is ineffective due to the terrain or tree canopy, marking the locations on a topographic map or aerial photograph at the time of sampling is the next best alternative.  When surface water samples are collected at sediment sampling locations, collect the surface water prior to the sediment sample (which will suspend the fines), no more than 1 foot above the sediment, unless samples are to be collected in a stratified water column as specified in the site-specific work plans.  When selecting a boat to access sampling locations on lakes, ponds, or rivers, make sure the hull design will not disturb the bottom and is stable enough to haul loaded samplers to the surface (flat vs V-shaped). Jon boats or small pontoons work well in most situations. Care must be given to avoid disturbing the bottom near the sampling locations with oars or a motor’s propeller. If necessary, use two anchors to anchor both ends of the boat to prevent rotation during sampling.  Prior to sampling, decontaminate nondisposable sample equipment according to SOP AMEC-10 and procedures outlined in the installation-specific work plan. 4.3.1 GENERAL SAMPLING PROCEDURES  Review carefully the HSP and/or the Hazard Assessment.  Don appropriate personal protection equipment (PPE), such as tall rubber boots or waders and personal floatation devices, as specified in the installation-specific work plan, prior to entering the water. A walking stick or trekking pole is often needed when wading in unclear water, to probe the bottom for sure footing and depth of water.  Due to uneven terrain, water hazards (currents, holes, ice, drowning, etc.), hazardous biota (snakes, spiders, stinging nettles, etc.), remoteness, and the hauling of equipment, gear, and sample containers, always sediment sample as a team of at least two personnel, with one team member as a site health and safety officer.  Approach submerged sampling locations from downstream and collect the sample facing upstream. Wading disturbs the sediment bottom and the suspended fines migrate downstream. Rev. 1 6 DATE STARTED: 07/21/2014  Never wade in water deeper than 2 feet, and generally no deeper than the top of the knee. Instability increases in deeper water, especially in a current, and it becomes more difficult to sample. If the water is not clear (unable to see the bottom), proceed with extreme caution, probing the bottom ahead with a walking stick for depth and unevenness. One of the team members should stay on or close to shore to hand equipment and supplies back and forth. If deemed necessary, the sampler may need to don a seat harness and be on a safety rope that is controlled by the other team member.  When using a hand coring device, slowly push the corer into the sediment until there is a noticeable resistance (usually indicating the channel or basin floor), or until the trailing end of the core barrel is at the sediment surface.  For sediment sampling using a boat, gently lower all grab and core samplers to the bottom so as not to create a bow wave and disturb the fine sediment on the surface. After the sample is collected at a given location, measure the depth of water with a weighted fiberglass tape and record this information on the sample collection log. These data are useful for profiling the lake or pond bottom.  Retrieve the sampling device slowly through the water to avoid washout by creating turbulent flow. Immediately extrude (for core samplers) or directly transfer (for grab samplers) the sample to a stainless steel bowl and check to see that sediment recovery is acceptable (no visible signs of sediment loss or washing). If sediment recovery is unacceptable or the volume is insufficient, collect another sample close to, but upstream of, the previous attempt.  Thoroughly homogenize the collected sediment sample in a mixing bowl (due to the stratified nature of sediment deposits), whether from a grab or core sampler, after removing excess water (being careful not to lose the fines in the process), rocks, sticks, leaves, and other organic debris. Then transfer the sediment into the sample containers using a stainless steel spoon or spatula. Fill the sample container such that little to no headspace exists.  Collect X-Y coordinates of the sample location using a portable GPS instrument. If a GPS is ineffective due to the terrain or tree canopy, mark the location in the field with a stake or flag.  Appropriately label and number the sample containers. The label will be filled out with a pen and will contain, at a minimum, the following information: - Project number - Location ID Rev. 1 7 DATE STARTED: 07/21/2014 - Sample number - Sample location - Sample depth - Sample type - Date and time of collection - Parameters for analysis - Sampler’s initials  Document the sampling event on a sediment sample collection log or an equivalent form as specified in the installation-specific work plan. Note any pertinent field observations, conditions, or problems in the field log. Any encountered problems (access issues, flooding by beaver dams, etc.) or unusual conditions should also be immediately brought to the attention of the Field Manager.  Appropriately preserve, handle, package, and ship the samples per SOP AMEC-11, or the installation-specific work plan. Rev. 1 8 DATE STARTED: 07/21/2014 SURFACE WATER SAMPLING SOP AMEC-08 (PFCs) 1.0 PURPOSE The purpose of this technical procedure is to describe the methodology for collecting surface water samples for PFC laboratory analyses and the associated water quality measurements. 2.0 SCOPE This procedure applies to all AMEC personnel and subcontractors with the responsibility for determining water quality and for the collection, preparation, preservation, and submittal of surface water samples for laboratory analyses. 3.0 REFERENCES U.S. Environmental Protection Agency (EPA), 1987, Compendium of Superfund Field Operations Methods, EPA 540/P-87/001a, OSWER 9355.0-14, September.

Rev. 1 1 DATE STARTED: 07/21/2014 5.0 GENERAL This section contains both the responsibilities and procedures involved with surface water sampling. Surface water samples may be collected either as composite or discrete samples, as described. The selection of sampling locations will be detailed in the installation-specific work plan. Actual sampling locations will be confirmed in the field prior to initiation of the sampling program. Samplers should anticipate accommodating on-site adjustment. When surface water and sediment samples are collected from the same location, water samples shall be collected first. 6.0 RESPONSIBILITIES Project Manager The Project Manager is responsible for ensuring that all sample collection activities are conducted in accordance with this standard operating procedure (SOP) and any other appropriate procedures. This will be accomplished through staff training and by maintaining quality assurance/quality control (QC/QC). Field Manager The Field Manager is responsible for periodic observation of field activities and review of field generated documentation associated with this SOP. The Field Manager is also responsible for implementation of corrective action (i.e., retraining personnel, additional review of work plans and SOPs, variances to QC sampling requirements, issuing nonconformances, etc.) if problems occur. Field Personnel Field personnel assigned to surface water sampling activities during drilling or probing are responsible for completing their tasks according to specifications outlined in this SOP and other appropriate procedures. All staff are responsible for reporting deviations from procedures to the Project Manager or the Field Manager. 7.0 PROCEDURE 7.1 Equipment Selection For most sites, a decontaminated bottle sampler attached to a pole (e.g., polyvinyl chloride [PVC] pipe) can be used as the sampling device, or the sample container itself can serve as the sampling device. Rev. 1 2 DATE STARTED: 07/21/2014 There are several more sophisticated sampling devices that can be used to collect water at discrete depths in deep bodies of water (e.g., Van Dorn, Kemmerer). However, for most routine site investigations of shallow lakes, ponds, and streams, this equipment is not necessary. The following equipment will typically be used during surface water sampling:  Water Quality Meter;  Laboratory-provided sample containers;  Self-adhesive sample bottle labels (Ensure PFC free);  High-density polyethylene (HDPE) or stainless-steel, dippers, bailers or other sampling device;  Appropriate health and safety equipment specified in the Health and Safety Plan;  Field notes and data sheets (e.g., sample collection form and Chain of Custody);  Pen;  Plastic bags (PFC free);  Cooler with ice (No chemical (aka “blue”) ice); and,  GPS receiver. 7.2 Pre-Sample Planning In general, surface water sample locations may include shallow or deep lakes, ponds and other types of impoundments, creeks and streams, ditches, low-lying areas, and intermittently wet drainage areas. These bodies of water may receive contaminant input from surface runoff; groundwater; or from direct discharge through a sluice, ditch, or pipe. If current information is not available, conduct a reconnaissance of all surface water sample locations to determine accessibility to the water body, depth of water, dangerous conditions (strong currents, boggy bottoms, log jams or beaver dams, waterfalls, steep banks, thick vegetation, etc.), and sampling and personal protection equipment selection criteria. Access to water bodies such as streams may be hampered by thick vegetation, and lakes and ponds that will require the use of a boat may not be accessible by road. Therefore, the logistics of getting sampling equipment and containers to and from the sites must be considered before attempting to sample. As a general rule, samples should not be collected after heavy rains or during storm events because they will not be representative samples reflecting normal (i.e., baseline) conditions. Rev. 1 3 DATE STARTED: 07/21/2014 When surface water samples are collected at sediment sample locations, the surface water sample should be collected prior to the sediment sample (which will suspend the fines), no more than 1 foot above the sediment, unless samples are to be collected in a stratified water column. If samples are collected in a stratified water column, the samples depths will be specified in the installation-specific work plans. The number of sample points and the specific analytes to be measured are provided in the installation-specific work plans. Sample locations and the number of samples collected will vary with the size of the water body and the nature of the source input. 7.2.1 Streams, Tributaries, and Creeks In moving water bodies such as streams, tributaries, and creeks, sample points should be located where the water is homogeneous both horizontally and vertically. Samples should be taken far enough downstream from the source input for the discharge to be completely mixed. Locations immediately below riffle areas will be vertically mixed and narrow channel areas promote horizontal or cross-channel mixing. Sampling should take place downstream of riffle areas and narrow channel areas where low flow and minimal turbulence conditions are present. The selection of strategically located sample sites may depend on several factors, such as homogeneity, accessibility, intake points for water supplies, stream velocity, and geomorphology. In general, a single grab sample collected at mid-depth in the center of the channel is adequate to represent the entire mixed cross-section of small streams less than 20 feet wide. The installation-specific work plan will designate whether a single mid-point sample, vertical profile samples, or discrete depth samples are required. If vertical profile samples are specified in the installation-specific work plan for larger and deeper streams or creeks, these samples should be taken from mid-stream just below the surface, at mid-depth, and just above the bottom and composited. If discrete depth samples are specified by the installation-specific work plan, these samples should be taken at the desired depths, if possible. The pH, temperature, specific conductivity, and dissolved oxygen should be measured for each sample point when vertical composite samples are collected. The number of vertical composites and the depths sampled are determined in the installation-specific work plan. Water depth can either be measured with a graduated staff (e.g., yardstick) at shallow depths or with one of various manual or electronic devices available for deeper depths (ASTM, 2007). Stagnated areas or pools in a stream or creek could contain different contaminant concentrations from the flowing areas, depending on the physical and chemical properties of Rev. 1 4 DATE STARTED: 07/21/2014 the contaminant and the proximity of these areas to the source. A sample may be taken at mid-depth to determine if these areas represent contaminant sinks. 7.2.2 Lakes, Lagoons, Ponds, and Impoundments The selection of representative sample points in standing bodies of water depends on the size, shape, and depth of the basin, and will be specified in the installation-specific work plan. Samples can be collected along a vertical transect and/or horizontal grid. The installation- specific work plan will designate whether a single mid-point sample, vertical profile samples, or discrete depth samples are required. In larger basins, stratification may inhibit uniform vertical mixing. In these instances, discrete depth samples may be collected at each stratification layer. In smaller basins, such as ponds, lagoons, and impoundments, the entire water column is generally uniformly mixed and one sample at the deepest point may be adequate. The deepest point is usually in the center of small ponds and other containment catch basins. For impoundments with a dam, the deepest point is generally near the base of the dam. Water depth can either be measured with a graduated staff (e.g., yardstick) at shallow depths or with one of various manual or electronic devices for deeper depths (ASTM, 2007). Wading into the water body to collect samples is not recommended in shallow lakes and ponds. Wading will disturb bottom sediments, which may contaminate the water column resulting in a false positive parameter result. Therefore, a boat is typically used to collect representative water samples in lakes, lagoons, ponds, and impoundments. 7.3 Sampling Procedures Laboratory-provided sample containers will be used to directly collect water samples if sample containers do not contain preservatives. Where required by site conditions, remote sampling into sample containers will be allowed by clamping the container onto the end of a clean extension rod. The extension rod must be made of material that does not include contaminants of interest. Beakers or dippers (i.e., transfer containers), which may be attached to extension rods, may be used if sample containers have preservatives or remote sampling site conditions prevent sampling by direct sample container immersion. The beakers or dippers will be obtained from a scientific instrument supplier so that the material composition of such a sampling container may be documented. The selected type of transfer device, the composition of this device, and the volume of the device will be recorded on the sample log. PFC free bailers (no Teflon or LDPE) may be used if direct access to the sampling point can be reached. Sample transfer Rev. 1 5 DATE STARTED: 07/21/2014 containers must be disposable or decontaminated (AMEC SOP-10) prior to each use. Discrete depth sampling devices may be used when the installation-specific work plan directs that specific depth intervals be sampled. 7.3.1 Equipment Decontamination Before sampling begins, sampling devices (e.g., metal bailers, beakers, dippers, etc.) shall be decontaminated. Mobile decontamination supplies may be utilized so that equipment can be decontaminated on-site. Each piece of sampling equipment shall be decontaminated before sampling operations and between sampling locations. Decontamination of field equipment will be performed in accordance with AMEC SOP-10. 7.3.2 General Surface Water Sampling Procedures  Samples will be collected first from areas that are suspected of being the least contaminated to minimize the risk of sample cross-contamination. In flowing water bodies, sampling shall progress from downstream to upstream to avoid sediment disturbance affecting subsequent samples.  Prior to sampling, the water body characteristics (e.g., size and depth) should be observed and described in the field logbook  Collect X-Y coordinates of the sample location using a portable global positioning system (GPS) instrument. If a GPS is ineffective due to the terrain or tree canopy, mark the location in the field with a stake or flag.  Don a clean pair of nitrile or equivalent PFC free gloves.  Surface debris (i.e., sticks, leaves, vegetation) will be cleared from the sample location prior to sample collection, taking care not to disturb bottom or attached sediments.  Measure water quality parameters (pH, dissolved oxygen, specific conductivity, and temperature) at each sample location prior to collecting a water sample. Samples for water quality parameters will be collected in a separate container at a like location and depth as the samples for laboratory analysis.  Collect the sample in accordance with the appropriate method-specific procedures in Section 7.3.3.  Identify, handle, and document the samples in accordance with SOP AMEC-11.  Document the sampling event on the sample collection form. Note: Collection of surface water samples in deep-water areas may require the use of a boat. The Health and Safety Manager or Site Coordinator shall be consulted for additional health and safety requirements. Rev. 1 6 DATE STARTED: 07/21/2014 7.3.3 Method Specific Sample Collection Procedures Samples Collected by Container Immersion Surface water sample collection by container immersion will be done in accordance with the following procedures:  The outside of all capped sample containers shall be triple rinsed with the surface water being sampled before filling the containers with the sample to be analyzed.  Submerge the sample container or transfer container below the water surface with minimal surface disturbance and with the open end pointed upstream.  If possible, the sample container or transfer container will be lowered no closer than 3 to 6 inches above the bottom sediments. Samples Collected by Bailer Surface water sample collection with a bailer will be done in accordance with the following procedures:  A disposable HDPE bailer or equivalent will be used;  Depth of water at each sampling site will be measured and the bailer will be lowered to the appropriate sampling location in accordance with the sampling plan;  If possible, the bailer will be lowered no closer than 3 to 6 inches above the bottom sediments;  The bailer will be inserted facing downstream and withdrawn very slowly and carefully to avoid agitation of the bottom sediments; and,  Transfer the sample from the bailer directly into the sample container. Minimize aeration of the sample as much as possible. Samples Collected by Discrete Depth Sampling Devices Surface water sample collection with a discrete depth sampling device will be done in accordance with the following procedure:  A Van Dorn, Kemmerer sampler or equivalent will be used.  Depth of water at each sampling site will be measured and the sampling device will be lowered to the appropriate sampling depth in accordance with the installation-specific work plan.  If possible, the sampling device will be lowered no closer than 3 to 6 inches above the bottom sediments. Rev. 1 7 DATE STARTED: 07/21/2014  The sampling device will be lowered facing upstream and opened once at the desired sampling depth. The device will be withdrawn very slowly and carefully to avoid agitation of the bottom sediments.  Transfer the sample from the device directly into the sample container. Minimize aeration of the sample as much as possible. 8.0 RECORDS Field notes shall be kept following the format specified in the site work plan and project QPPP. The following information is required according to the sampling method performed:  GPS coordinates, or distance to two fixed objects, or distance and compass bearing from at least one fixed object;  Distance of sample collection point from right or left edge of water;  Water depth;  Estimate of surface area of water body;  Sample depth interval;  Sample collection method (grab, discrete);  Surface water and site conditions (e.g., floating oil or debris, gassing);  Location of any discharge pipes, sewers, or tributaries;  Instrument calibration;  Required site maps (If a staff gauge is measured and not co-located with surface water location it must be included in the site map).; and,  Weather observations (e.g., wind speed, is it sunny or cloudy, and approximate wave height).

Influent - Un-treated groundwater entering into a groundwater treatment system. 4.0 PROCEDURE This section contains both the responsibilities and procedures involved with groundwater treatment system sampling. Proper groundwater treatment system sampling procedures are necessary to insure the quality and integrity of the samples. The details within this SOP should be used in conjunction with installation specific work plan addendums. The installation specific work plan addendums will generally provide the following information:  Sample collection objectives;  Locations of groundwater treatment system samples to be collected;  Numbers and volumes of samples to be collected; Rev. 2 1 DATE STARTED: 08/21/2014  Types of chemical analyses to be conducted for the samples;  Specific quality control (QC) procedures and sampling required;  Any additional groundwater treatment system sampling requirements or procedures beyond those covered in this SOP, as necessary; and,  At a minimum, the procedures outlined in this SOP for groundwater treatment system sampling will be followed. 4.1 RESPONSIBILITIES Project Manager The Project Manager is responsible for ensuring that sample collection activities are conducted in accordance with this SOP and any other appropriate procedures. This will be accomplished through staff training and by maintaining quality assurance/quality control (QA/QC). Field Manager The Field Manager is responsible for periodic observation of field activities and review of field generated documentation associated with this SOP. The Field Manager is also responsible for implementation of corrective action (i.e., retraining personnel, additional review of work plans and SOPs, variances to QC sampling requirements, issuing nonconformances, etc.) if problems occur. Field Personnel Field personnel assigned to groundwater sampling activities are responsible for completing their tasks according to specifications outlined in this SOP and other appropriate procedures. All staff are responsible for reporting deviations from procedures to the Project Manager or Field Manager. 4.2 GROUNDWATER TREATMENT SYSTEM SAMPLING REQUIREMENTS 4.2.1 Treatment Plant Access Contact treatment plant personnel prior to sampling to procure access and to confirm applicable site specific and system specific health and safety requirements. 4.2.2 Influent and Effluent Sampling Considerations Upon arriving at treatment plant, the treatment plant operator will inform the sampler if the treatment system is operating or if it is off. The operator will also show the sampler the location of the sampling ports. If the treatment system is off, the sampler will wait until the operator starts the system. Once the system is operating, sampling will be performed as Rev. 2 2 DATE STARTED: 08/21/2014 described below. If the treatment plant is operating upon arrival, perform the minimum one minute purge and sample as described below.  Inspect the laboratory provided sampling bottles prior to sampling to ensure that they are appropriate for the samples being collected, are undamaged, and have had the appropriate types and volumes of preservatives added. The types of sample containers to be used and sample preservation requirements will be provided in the installation specific work plan addendums.  Calibrate all field analytical test equipment (e.g., pH, specific conductance, dissolved oxygen, oxidation-reduction potential, turbidity, and temperature) according to the instrument manufacturers’ specifications or installation-specific work plan. Calibration results will be recorded on the appropriate form(s) as specified by the project work plans. Instruments that cannot be calibrated according to the manufacturers’ specifications will be removed from service and tagged.  Open the sampling port.  Purge for a minimum of 1 minute, a high flow volume into a bucket to flush the sampling port tube. o During the purge, collect one set of physical parameters (i.e., pH, specific conductance, dissolved oxygen, oxidation-reduction potential, turbidity and temperature). Table 4-1 Parameter Units pH Standard Units Micromhos/centimeter Specific Conductivity (umho/cm, or µS/cm) Temperature Degrees Celcius (ºC) Oxidation-Reduction Millivolts (mV) Potential (ORP) Dissolved Oxygen Milligrams/liter (mg/L) Nephelometric Turbidity Turbidity Units (NTUs) Rev. 2 3 DATE STARTED: 08/21/2014  Upon completion of the one minute purge, adjust the flow rate downward prior to filling the laboratory supplied sample bottles.  Collect the sample directly into the provided sample bottle(s) (containers), allowing the discharge to flow gently down the inside of the bottle, minimizing aeration of the sample. Document the sampling event on the Groundwater Sample Collection Form.  Appropriately seal, store, handle, and ship the samples per SOP AMEC-11.  Sample both the effluent and influent ports following the same procedures.  Upon completion of sampling, empty the purge water from the bucket into a location determined by the treatment plant operator. As the sample is collected directly into the laboratory provided container and directly from the system itself, there is no decontamination required, though fresh gloves should be donned prior to each sampling event at each port. Rev. 2 4 DATE STARTED: 08/21/2014 DRILLING, DEVELOPMENT, AND HEAVY EQUIPMENT DECONTAMINATION SOP AMEC-10 (PFCs) 1.0 PURPOSE This Standard Operating Procedure (SOP) establishes guidelines for use by field personnel in the decontamination of drilling, development, and heavy equipment when conducting PFC environmental assessments. The details within this SOP are applicable as general requirements for drilling and heavy equipment decontamination, and should also be used in conjunction with project work plans. 2.0 REFERENCES U.S. Environmental Protection Agency (EPA), 1987, Compendium of Superfund Field Operations Methods, EPA 540/P-87/001a, OSWER 9355.0-14, September.

This SOP and the project work plans should be reviewed before implementing drilling, development, and heavy equipment decontamination at the project site. The Project Manager has the responsibility for ensuring that decontamination of drilling and heavy equipment is properly performed through staff training and by maintaining quality assurance/quality control (QA/QC). Rev. 1 1 DATE STARTED: 07/21/2014 The Field Manager has the responsibility for periodic review of procedures and documentation associated with the decontamination of drilling and heavy equipment. If perceived variances occur, the Field Manager is also responsible for issuing notices of nonconformances and requesting corrective actions. Additionally, the Field Manager will perform inspections and monitoring of the decontamination activities. Project staff assigned to drilling, development, trenching, or construction activities are responsible for ensuring that subcontractors or equipment operators properly decontaminate drilling, development, and heavy equipment associated with those tasks. Project staff are also responsible for documenting the decontamination activities in a field log and/or appropriate form(s) as specified in the project work plans. 4.2 General This section provides requirements for the construction of a temporary decontamination facility for drilling, development, and heavy equipment and the decontamination procedures to be followed. The project work plans will provide specific information regarding:  Types of equipment requiring decontamination under this SOP;  Location of the decontamination station;  Types and/or specifications on materials to be used in the fabrication of the decontamination station; and,  Types of materials and additional details on the procedures to be used in the decontamination process. Field personnel associated with construction of the decontamination station or decontamination of drilling or heavy equipment must read both this SOP and the project work plans prior to implementation of related decontamination activities. 4.3 Decontamination Facility A decontamination facility will be set up in an area exclusively for decontamination of drilling, well development, and/or heavy equipment. Decontamination of drilling, development, and heavy equipment will be conducted within the station. At a minimum, the station will be constructed such that all rinsates, liquid spray, soil, debris, and other decontamination wastes are fully contained and may be collected for appropriate waste management and disposal. The facility may be as simple as a bermed pad lined with approved PFC free high density polyethylene sheeting with an impermeable sump for collecting rinse water. More sophisticated designs involving self-contained metal decontamination pads in combination with bermed polyethylene sheeting may also be used, depending on project- Rev. 1 2 DATE STARTED: 07/21/2014 specific requirements. These requirements along with specific equipment and construction specifications for the decontamination facility will be provided in the project work plans. 4.4 Decontamination of Downhole Equipment Downhole drilling and development equipment (including but not limited to drill pipe, drive casing, drill rods, bits, tools, nondisposable bailers, etc.) will be thoroughly decontaminated before mobilization to each site and between borings or wells at each site or as required in the project work plans. The standard procedure will be performed as described below. Decontamination will be performed in accordance with this SOP and the project work plans.  Appropriate personal protective equipment (as specified in the project work plans) must be worn by all personnel involved with the task to limit personal exposure.  Equipment caked with drill cuttings, soil, or other material will initially be scraped or brushed. The scrapings will be containerized and appropriately disposed.  Equipment will then be sprayed with potable water using a high-pressure washer.  Washed equipment that will be used to collect the samples or will come into contact with the sampled media (such as the non disposable stainless bailer used for well development) will then be “final” rinsed with lab provided “PFC-free” water.  Decontaminated downhole equipment (such as drill pipe, drive casing, bits, tools, bailers, etc.) will be placed on clean PFC free high density polyethylene (HDPE) plastic sheeting to prevent contact with contaminated soil and allowed to air dry. If equipment is not used immediately, it will be covered or wrapped in PFC free, approved plastic sheeting to minimize airborne contamination.  Decontamination activities will be documented by the Field Manager, lead geologist, or lead engineer in the field log and/or appropriate form(s), as specified in the project work plans. 4.5 Decontamination of Heavy Equipment Heavy equipment (e.g., drill rigs, development rigs, backhoes, trucks, and other earthmoving equipment) will be decontaminated between drilling sites or inside the contaminant reduction area prior to entering and leaving an exclusion zone. Decontamination will be performed in accordance with the project work plans. The standard procedure will be performed as described below.  Appropriate personal protective equipment will be worn by all personnel involved in the task, in order to limit personal exposure.  Heavy equipment caked with drill cuttings, soil, or other material will be initially scraped or brushed to remove bulk soil. Rev. 1 3 DATE STARTED: 07/21/2014  Heavy equipment will then be moved to the decontamination pad and sprayed with potable water using a high pressure washer.  Those portions of the heavy equipment that will potentially contact the sample will be rinsed in a final rinse with lab provided “PFC-free” water.  During the decontamination effort, fluid systems should be inspected for any leaks or problems, which might potentially result in an inadvertent release at the site, thereby contributing to the volume of waste or contamination. Decontamination of heavy equipment should be performed before moving equipment between sites or before leaving the site.  Decontamination activities will be documented in the field log and/or appropriate form(s), as specified in the project work plans.  Between boreholes at the same site, the back-end of the drilling rigs will be washed with potable water until surfaces are visibly free of soil buildup.

Standard Guide for Sampling Chain-of- Custody Procedures. D 4840-95. 4.0 DEFINITIONS Custody – physical possession or control. A sample is under custody if it is in possession or under control so as to prevent tampering or alteration of its characteristics. Sample Label – a record attached to samples to ensure legal documentation of traceability. Chain-of-Custody Record – legal documentation of custody of sample materials and instructions for analytical laboratory. 5.0 GENERAL An essential part of the sampling activities of any environmental project is assuring the integrity of the sample from collection to data reporting. Sample labels and Chain-of-Custody forms are used to document identification and handling of samples from the time of collection through the completion of chemical analysis. In some projects, analytical data may be used in litigation. Accountability of the history of a sample must be available to demonstrate that the data are a true representation of the environment. The chain-of-custody record is used as evidence in Rev. 1 1 DATE STARTED: 07/21/2014 legal proceedings to demonstrate that a sample was not tampered with or altered in any way that may bias the analytical accuracy of the laboratory results. It is extremely important that chain-of-custody records be complete, accurate and consistent. 6.0 RESPONSIBILITIES 6.1 Project Manager The Project Manager is responsible for overall compliance with this technical procedure. 6.2 Field Manager The Field Manager shall ensure that the samples are correctly collected, labeled, tracked by chain-of-custody, and stored until they are delivered directly to the shipper or laboratory (i.e., on-site or off-site). 6.3 Sample Collector The Sample Collector shall ensure the samples are correctly collected, labeled, tracked by chain-of-custody, and stored until they are delivered directly to the Sample Shipper or laboratory (i.e., on-site or off-site). The Sample Collector shall maintain custody of the samples until they are relinquished to the Sample Shipper or laboratory. The Sample Collector shall be responsible for informing the Sample Shipper of sampling conditions and if any of the samples are potentially hazardous. (NOTE: The Sample Collector and Sample Shipper can be the same person.) 6.4 Sample Shipper The Sample Shipper shall pack the sample shipping coolers, ensure that the chain-of-custody forms are correct, and ship and/or deliver the samples to the laboratory. The Sample Shipper shall determine which samples are potentially hazardous and ship them accordingly. 7.0 PROCEDURE 7.1 Sample Custody Sample custody procedures are designed to ensure that sample integrity is maintained from collection to final disposition. A critical aspect of sound sample collection and analysis protocols is the maintenance of strict chain-of-custody procedures as described in this technical procedure. Chain-of-custody procedures include tracking and documentation during sample collection, shipment, and laboratory processing. A sample is considered to be in an individual's custody if it is (1) in the physical possession of the responsible party; (2) in view of the responsible party after being in their possession (3) secured to prevent tampering; or (4) placed in a designated, secure area that is controlled and restricted by the responsible party. Rev. 1 2 DATE STARTED: 07/21/2014 Custody will be documented throughout all sampling activities on the chain-of-custody record for each day of sampling. This record will accompany the samples from the site to the laboratory. All personnel with sample custody are required to sign, date, and note on the record the time when receiving and relinquishing samples from their immediate custody. Any discrepancies will be noted at this time. Samples will be shipped to subcontract laboratories via overnight air courier. Bills of lading will be used as custody documentation during this time and will be retained as part of the permanent sample custody documentation. In some cases, samples may be hand delivered to the laboratory; hand delivery will be noted on the chain-of- custody form. The subcontractor laboratory is responsible for sample custody once samples are received. 7.2 Sample Labels A label will be attached to all sample containers at the time of sample collection. The label will contain the following information:  Unique chain-of-custody control number;  Analyses requested; and,  Preservative used. When sample collection is complete; the Sample Collector fills in the following information in ink:  Date and time of sample collection; and,  Sampler’s initials. 7.3 Chain-of-Custody Record Chain-of-custody forms will be used to document the integrity of all samples to maintain a record of sample collection, transfer of samples between personnel, shipment of samples, and receipt of samples at the laboratory, chain of custody forms will be filled out for each sample/analysis at each sampling location. The chain of custody forms shall include the following information:  Project name and project number if applicable;  Name and address of laboratory to receive the samples;  Chain-of-custody control number;  Sample type, sample method;  Location ID, sample ID;  Matrix code;  Analyses requested;  Field QC for matrix spike (MS)/matrix spike duplicate (MSD), if applicable; Rev. 1 3 DATE STARTED: 07/21/2014  Container type, size and number;  Preservatives used;  Turn-around-time for laboratory analysis; and,  Comments to Laboratory or Sample Collector, if applicable. The Sample Collector will enter the following information using black or blue ink:  Sampler’s initials;  Date of collection;  Time of collection (24-hour format);  Depths, if applicable;  Pump/equipment number, if applicable; and,  Void reason, if applicable. The Sample Collector shall verify the chain of custody record is complete, accurate in all aspects, and consistent with all other sample documentation (e.g., number of samples, sample labels, field logs). The Sample Collector will sign the "Sampled By” and “Relinquished By" fields on the Chain of custody record, marking the date and time custody is transferred to the Sample Shipper or other authorized person. The Sample Shipper will perform the following duties:  Obtain the signature of the Sample Collector to transfer sample custody;  Record the carrier service and airbill number on the chain of custody;  Sign and enter the date and time relinquished to the shipper; and,  Prepare the samples for shipment from the field to the laboratory. The Sample Shipper or sample custodian will sign the "Received By" box, marking the date and time of receipt of the samples from the Sample Collector or other sample custodian. Every transfer of physical custody shall be documented on the chain-of-custody record. Any corrections to the chain of custody form entries will be made by a single-line strike mark through the incorrect item, and then entering the correct entry adjacent to the strikeout item. Corrections will be initialed and dated by the person making the change. After the form has been inspected and determined to be complete, the sample shipper will sign, date, and note the time of transfer and will reference a shipper tracking number on the form. The chain of custody form will be placed inside the cooler after the sample packer has detached or made an appropriate copy of the form. Field copies of the completed chain of custody forms maintained in project files. Rev. 1 4 DATE STARTED: 07/21/2014 7.4 Overnight Sample Storage In some cases, samples that cannot be shipped immediately to a laboratory must be temporarily stored in an AMEC controlled sample refrigerator until arrangements can be made for delivery. The sample custodian shall place samples in the refrigerator [samples and signed chain of custody record(s)] and secure the refrigerator with a unique, keyed lock, restricting access to one custodian at a time. A temperature blank must accompany samples overnight. Samples temporarily stored in the refrigerator must be received by the custodian that placed them in storage, and in turn, may be “relinquished to” the appropriate laboratory, the Sample Shipper or another sample custodian. Each transfer of custody shall be recorded on the appropriate chain of custody form(s). 8.0 RECORDS Distribution of the chain of custody record:  Original sealed in a plastic bag and taped inside the top of the shipping container; and,  Copies to the Project Manager. Rev. 1 5 DATE STARTED: 07/21/2014 PROTOCOL TO PROVIDE WATER FREE OF PERFLUORINATED COMPOUNDS FOR COLLECTION OF FIELD BLANKS AND EQUIPMENT BLANKS SOP AMEC-12 (PFCs) 1.0 PURPOSE The purpose of this Standard Operating Procedure (SOP) is to identify and limit trace perfluorinated compound (PFC) detections introduced through low-level PFC contamination in the laboratory-supplied water used for field blanks, equipment blanks, and decontamination of sampling equipment; ambient PFC contamination from atmospheric conditions or sample containers; or decontamination procedures. The following procedures will be used to provide traceable PFC-free water for equipment decontamination, field blanks, and equipment blanks. 2.0 SCOPE This procedure applies to all AMEC personnel and subcontractors who use or provide PFC-free water for field blanks, equipment blanks, and equipment decontamination. 3.0 REFERENCE Department of Defense, 2013. Quality Systems Manual for Environmental Laboratories, Version 5.0. July. 4.0 DEFINITIONS Per the Department of Defense Quality Systems Manual for Environmental Laboratories Version 5.0, water will be defined as being PFC-free if there are no target analyte detections at concentrations equal to or greater than half the limits of quantification (LOQs) specified in the Table 1. Target analyte detections at or greater than half the LOQ will disqualify all the water in the associated batch from being used for equipment decontamination, field blanks, or equipment blanks. Table 1.

The laboratories must certify that each batch of deionized water is PFC-free following the procedures specified below before shipment to the field. Procedures to be used for certification of the PFC-free water are: 1) If the laboratory provides water from its internal ultrapure water system, that water must be used for the routine preparation of method blanks for PFC analysis, and the laboratory must: a. Provide copies of their control charts showing that PFC concentrations in the method blanks are consistently less than the concentrations specified in Section 7 below with each shipment of water; b. Fill a bottle from each “manufacturers lot” of bottles/caps with the laboratory’s PFC-free water, and analyze an aliquot of water from that bottle to show that the water in the bottle meets the requirements of Section 7 below; and, c. Assign a unique Batch Number to each shipment of PFC-free water to AMEC, and maintain a record of the preparation date and bottle/cap lot number used to prepare that PFC-free water batch. If multiple bottle types (e.g. cubitainers for large volumes and 125 ml bottles for rinsate blanks) are used, separate batch Rev. 1 2 DATE STARTED: 07/21/2014 numbers should be used for each bottle type. 2) If the laboratory provides purchased ultra pure water to AMEC for equipment decontamination and blanks, the laboratory must analyze an aliquot of each manufacturer’s batch before the water is shipped to AMEC. If target analytes are detected in the water at concentrations equal to or greater than half the LOQs specified in Table 1 the water must be considered contaminated, and it will not be shipped to AMEC. The manufacturer name and batch or lot number will be used for purposes of maintaining traceability of purchased water. If target analytes are not detected at concentrations equal to or greater than half the LOQs specified in Table 1, the water is suitable to be shipped to AMEC. The laboratory must provide a certificate of analysis with results for the water batch to the AMEC’s Project Chemist, or designee, before the water is shipped to the field. Each batch of PFC-free water must be clearly marked with a unique batch identification number. AMEC Prior to use, the field crew will collect a field blank from each batch of PFC-free water by pouring an aliquot of the water into a sample container. Before sample collection, field crews will decontaminate the equipment and will using the PFC-free water as a final rinse. During sampling, field crews will collect equipment blanks at a frequency of 1 per 10 samples collected using the same sampling equipment. AMEC field crews will clearly associate field blanks and equipment blanks with both the associated laboratory water batch identification number and associated field samples on daily field forms and/or in an electronic sample tracker. The AMEC Chemist will maintain records and will chart results of the source water, equipment blank, and field blank analytical data. AMEC will evaluate the data to identify any trends or anomalies that warrant a change of this or field sampling procedures. 7.0 EVALUATION This procedure will provide documentation that the source water used for equipment rinsing and blanks is PFC-free, with PFC levels less than 1/40 the project action limit for perfluorooctanoic acid (PFOA), less than 1/20 the project action limit for perfluorooctanesulfonic acid (PFOS), or less than half the LOQ for analytes without project action limits. AMEC will track analyte concentrations in the water from shipment from the laboratories, to the field, and ultimately to the water’s use to rinse sampling equipment. This Rev. 1 3 DATE STARTED: 07/21/2014 will eliminate concern about the PFC-free water itself as a source of contamination, and facilitate evaluation and identification of sources or actions that contribute to cross- contamination, so that the project team can adjust procedures if needed. The blanks dataset will be used as part of AMEC’s overall quality control assessment of ambient sources of PFC contamination relative to sample concentrations.
