SUBMITTAL: SAMPLING AND ANALYSIS PLAN ENVIRONMENTAL SAMPLING AT DP44, Ff09, AND LF03 (MW0308) EIELSON AFB OPERABLE UNITS 3, 4, AND 5 EIELSON AFB, ALASKA 1.0 INTRODUCTION AGRA Earth & Environmental, Inc. (AGRA) developed this Sampling and Analysis Plan (SAP) to meet the objectives of field, sampling and laboratory analysis for site testing at Operable Units (OUs) 3, 4, and 5 at Elelson Air Force Base (AFB), Alaska. This SAP should be used in conjunction with the AGRA Quality Assurance Program Plan (QAPP). The QAPP is approved by and on file with the Alaska Department of Environmental Conservation (ADEC) Northern Regional Office. Field methods that vary from the QAPP, but are accepted industry practices, are described in this SAP. 2.0 SOIL BORINGS AGRA will advance nine soil borings to a depth of 4 feet using a 2-inch solid-stem drilling auger and appropriate drilling equipment. It is probable that the drilled interval from ground surface to the 4-foot depth will be frozen during this investigation. As a result, AGRA anticipates that minimal soil cuttings will be generated during the drilling process. Drill cuttings, if any, will be combined in a single Air Force-supplied 55-gallon open-top steel drum. One drum will be adequate based on the fact that the analyses requested for this project suggest a potential sole source of the contaminants encountered, if any,, and that the generated volume of soil cuttings will be less than one cubic yard. The drummed soils will be left on shte for Air Force disposal. The drums used for disposal will be labelled with an all-weather permanent paint pen to include J ~~the following information: media type (soil cuttings and so forth), sampling location (well ID, boring location), project name, and date of generation. A trained field geologist/engineer will observe the boring procedure, measure the specific boring locations in relation to an identified reference point on site by triangulation using a cloth tape, record boring and sampling depths, and visually classify the soil types encountered.

The location of each soil boring will be agreed upon by Elelson project personnel prior to the start of the field program. The drill auger will be advanced to the 4-foot depth in each boring location. The auger will then be removed from the boring without rotation to preserve the order of the soils which adhere to the auger flights. Upon retrieval of the auger, the AGRA field representative will obtain a soil grab sample from the 2-foot to 4-foot depth interval. Soil will be collected in an amount sufficient to fill the required number of sample jars and to allow for a field screening headspace measurement. In the event that the volume of soil adhering to the removed auger is insufficient to complete the required sample collection, AGRA personnel will reinsert the auger and advance to the 4.5-foot depth to loosen the soil that may be frozen. The field geologist/engineer will then use a manual bucket auger of sufficient length to retrieve additional soils to complete the sampling. Duplicate or split soil samples collected for' quality control purposes for less volatile compounds are normally obtained by thoroughly mixing the retrieved sample in a stainless steel bowl prior to placing the sample in the necessary laboratory sample jars. However, because the required analyses are primarily for volatile constituents, duplicate samples will be collected by grab sample from immediately adjacent locations on the retrieved drilling auger to avoid unnecessary sample disturbance. Because of the natural heterogeneity of soil types, the analytical results obtained for the split samples may lie outside the acceptable comparison range for some compounds. While on site, the AGRA field geologist/engineer is the only person authorized to collect soil samples for laboratory submission and handle necessary sampling equipment. The field sampler will use a new pair of nitrile sampling gloves prior to handling each retrieved sample. 3.1 Visual Classification Upon retrieval from the boring, the sampled soils will be inspected by the field sampler. Soil types will be visually classified using the Unified Soil Classification System (USCS) as related in ASTM D: 2488 Description and Identification of Soils. 3.2 Field Screening A portion of each collected sample will be reserved for field headspace screening using a Thermo Environmental Instruments, Inc. Model 5800 Organic Vapor Meter (OVM). The headspace sample collection method for this project will consist of filling a clean plastic sealable bag half full of soil and then sealing the bag. The headspace samples will be allowed to warm =FAGRAGru Earth & EnvironmentalGru

The OVM probe will then be gently inserted into the plastic bag to sample the headspace in the bag. The highest measured OVMV reading will be recorded as the soil vapor headspace measurement for each sample. This screening method, though modified from the AGRA QAPP, is an acceptable screening method in general agreement with the screening protocol endorsed by the United States Environmental Protection Agency (EPA). The OVM will be calibrated prior to the start of field work and will be calibrated again at the start of each working day when its use is needed. Periodic calibration checks will be completed throughout the time period during which the OVMV is operating. At the end of each work shift, the OVM will be post-calibrated to monitor equipment operability. An OVM calibration log will be maintained with the instrument. The OVM calibration procedures are presented in the AGRA QAPP. 4.0 GROUNDWATER MONITORING WELL SAMPLING AGRA field personnel will measure the depth to water as referenced from the top of the monitoring welt casing using a Keck IR-47 Interface probe or similar liquid level indicator probes. The Keck probe is capable of distinguishing between water and liquid hydrocarbons. The depth to the well bottom will also be measured so that the height of the water column in the well may be determined. The Keck interface probe will be decontaminated prior to use at each well. Prior to sampling, each well will be purged to remove standing, potentially stagnant water. Purging will be accomplished by bailing with a disposable bailer. AGRA will remove at least three well volumes of water from each well, or until dry, during well purging. Purged water from the monitoring wells will be containerized in Air Force-supplied 55-gallon open-top steel drums. The drummed purge water will be left at each site for Air Force disposal. The drums used for storage of the removed water will be labelled as outlined in Section 2.0 of this plan. Groundwater samples will be obtained using disposable bailers to avoid cross-contamination of the wells. The groundwater will be decanted from the bailer into laboratory-prepared sampling jars. When the required number of sampling containers are filled, the samples will be immediately labelled and placed in a chilled cooler. 5.0 REQUIRED ANALYSES The following tables describe the total number of samples to be collected at each location as per the Statement of Work for this project. All samples will be submitted to Commercial Testing & Engineering Co.

This rinsing step will be replaced with a clean water rinse. Liquid level probe decontamination consists of wiping the probe to remove particulates and residual water as the probe is being removed from the well. The probe is then washed in soapy water and rinsed with distilled water. 6.2 Soil Boring Equipment All drilling equipment and soil augers will be decontaminated by high-pressure hot-water washing prior to arriving on site. Nine distinct pre-decontaminated 5-feet lengths of drilling auger will be employed to advance the nine soil borings. The drill bit attached to the lead part of each advanced auger will be decontaminated on site by first removing gross soil particulates, washing the bit in a warm soapy water solution, rinsing with warm clean water, and finally rinsing with distilled water. This procedure will be repeated using an Alconox solution and a hot water rinse. The hot water will remain inside the heated field vehicle while on site. The water used for equipment decontamination will be containerized in an Air Force-supplied 55-gallon open-top steel drum and left on site for Air Force disposal. The drums utilized for storing the spent water will be labelled as described in Section 2.0 of this SAP. 7.0 DOCUMENTATION Sampling documentation and other field work will be logged by the on-site AGRA field geologist/engineer in a bound field notebook. At the close of sampling aet each site (OUs 3,4 and 5) a chain-of-custody (COG) form will be completed using the information from the field notebook. The form will be signed by the field sampler and will accompany the samples in a sealed plastic bag taped to the Inside of the shipping cooler. OF AGRA Earth & Environmental Group
