Collect soil samples at 5-foot intervals from each boring, beginning at 5 feet bsg,utilizing. <br /> a California split-spoon sampler and pre-cleaned2-inch by 67inch brass sleeves. <br /> 6. ' Preserve soil in the middle brass sleeve,by covering both ends-with Teflon sheets, capping, <br /> and sealing with tape. <br /> 7. Label the preserved samples with boring (well) designation; sample depth, date, sampling <br /> time,and sampler's initials. <br /> 8. Store the samples under ice and transport the samples in a chilled ice chest to a state-certified <br /> laboratory for analysis. y <br /> 9. Screen soil sample duplicates for the presence of,volatile organic compounds using an <br /> organic vapor.meter equipped with a photo-ionization detector,(FID) pre-calibrated to <br /> isobutylene. <br /> 10. Log the boring in accordance with.the Unified Soil:Classification System: " <br /> 11. Analyzed three selected soil samples for.TPH-g, BTE&X, MTBE, BA,DIPE, ETBE and <br /> TAME utilizing the analytical methods previously noted. <br /> 12. Complete the boring as a two-inch diameter ground water monitoring well in accordance <br /> with.the well design shown in Figure 3, <br /> 13. Use a surge-block or bailer during the construction of the ground water well to set the sand' <br /> filter material, prior to installation of the bentonite transition seal. <br /> 14. Store cuttings on-site in properly labeled, D..O.T.-approved, model 17-H 55-gallon drums <br /> pending laboratory analysis and proper disposal. <br /> 15. Containerize rinseate generated during drilling activities in properly labeled D.O.T: <br /> approved, model 17H 55-gallon drums, and store on-site-in an area lacking general public <br /> access. <br /> 16. Develop the new monitoring well utilizing a steel bailer and_a submersible pump until <br /> produced water is essentially sediment'free. <br /> 4.2. COLLECTION OF GROUND WATER SAMPLES <br /> 1. Measure to the nearest 0.01 foot, the static water level.in the new.well.. <br /> 2. Purge the ground water monitoring well using a dedicated bailer or purge-pump..At least., - <br /> three volumes of water will be removed from the well. Stabilization parameters. <br /> temperature, pH, and conductivity) will be measured at.one-gallon intervals. <br /> Advanced GeoEnvironmentai, Inc. <br />
