ATTACHMENT # 1 SOIL BORING <br /> Soil Boring Procedures <br /> Soil borings will be drilled with a hollow stem flight <br /> auger, equipped with a moda-fled California split spoon sampler. <br /> Where possible, samples will be taken in conjunction with a <br /> Standard Penetration Test. All equipment will be steam cleaned <br /> before each boring to prevent cross-contamination. <br /> Samples will be taken every 5 ft. down to the saturated <br /> zone, or 5 ft. -into a massive clay, or 5 ft. below any evidence <br /> of contamination, based on field observation. Samples will be <br />' encased in a brass liner, both ends sealed in aluminum foil, <br /> capped, and placed in iced storage for transportation to a state <br /> certified analytical laboratory. A chain-of-custody document <br /> will be maintained for all laboratory samples . <br /> The soil borings will be logged by qualified geologic <br /> personnel under the supervision of a geologist registered in the <br /> state of California. The soil samples will be classified <br /> according to the Unified Soil Classification System. Logs will <br /> be prepared of each boring. <br /> If ground water is encountered in the soil borings, it will <br /> be noted on the logs and a sample will be taken by standard <br /> bailing methods from within the hollow flight auger. It will be <br /> placed in a glass vial with a teflon seal and placed in iced <br /> storage for transportation to a state certified laboratory. <br /> At the completion of the boring, it will be abandoned by <br /> filling with a bentonite slurry and sealed with a cement plug. <br /> I <br /> CONDOR <br />
