Groundwater Sample Collection <br /> One full set of groundwater samples will be collected at the conclusion of all <br /> drilling and well-development work. The two new wells will then be incorporated into <br /> the existing quarterly groundwater-sampling and reporting program. <br /> Each well will be purged of no less than three casing volumes of water in order to <br /> ensure sampling the formation groundwater. Purging will be carried out using the <br /> dedicated bladder pump. All purged water volumes will be recorded on the sample <br /> collection log sheet along with periodic pH, temperature and conductivity measurements. <br /> Groundwater samples will be collected directly into laboratory-supplied containers <br /> directly from the pump discharge tube. Sample volumes will consist of two one-liter <br /> amber glass containers and a pair of 40-m1 VOA vials. Each sample container will be <br /> filled completely, capped and then checked for trapped air by inversion and tapping. If an <br /> air bubble is observed in a vial,that vial will be reopened and topped off with additional <br /> well water until no bubbles exist when the container is inverted. All samples will be <br /> properly labeled and then placed into a chilled cooler for transportation to a State- <br /> certified laboratory for analysis. Strict chain-of-custody protocol will be followed during <br /> all phases of sample handling. <br /> Laboratory Analyses & Reporting <br /> All soil and water samples taken from the project site will be submitted to a state <br /> certified laboratory for analyses for total petroleum hydrocarbons as diesel (TPH-Diesel; <br /> EPA method 8015M) and benzene,toluene, ethyl benzene and xylenes (BTEX; EPA <br /> method 8021 B). Upon receiving the analytical results from the soil samples and the first <br /> set of groundwater samples a comprehensive report about the project will be generated <br /> and submitted to EHD. This report will present a narrative summary of all well <br /> construction details, boring logs, development records, analytical results and chain-of- <br /> custody sheets and copies of all field sheets. The report will be submitted to EHD within <br /> 30-days of project completion and all laboratory analytical data and results will also be <br /> submitted electronically to the GeoTracker database. <br /> Waste Management <br /> All purged groundwater will be temporarily stored on-site in properly labeled, 55- <br /> gallon drums pending the outcome of the laboratory analyses. If the laboratory results <br /> indicate that contamination exists,then the materials will be picked up and manifested <br /> with the plant's routine hazardous waste collection. If contamination is not found then the <br /> purged water will be disposed of to ground surface at the end of each sampling event. <br />
