All borings will be backfilled to the surface with neat cement slurry after sampling is <br /> completed. <br /> Soil cuttings and decontamination water generated during the investigation.will be disposed of <br /> following receipt of the laboratory analytical results. The cuttings and decontamination water <br /> will be transported for disposal or recycling by a licensed hazardous waste hauler. <br /> Task 4. Groundwater Investigation Report Preparation <br /> A report on the groundwater investigation activities will be prepared after all of the results are <br /> received from the analytical laboratory. The report will include: assessment procedures, a soil <br /> boring location map, soil boring logs, a tabulated summary of analytical results, laboratory data <br /> sheets and chain of custody documentation, evaluation of the data collected, conclusions, and <br /> recommendations. In addition, the report will also contain information gathered by ATC <br /> regarding the location and construction of domestic, municipal and agricultural wells within <br /> 2,000 feet of the subject site, and the operating history of the site USTs. <br /> E} SCHEDULE <br /> �1 Following approval of this Work Plan by the San Joaquin County Environmental Health <br /> (1 Division, we expect that permit acquisition and mobilization for the field:work will require <br /> approximately 4 weeks. The summary report will be submitted within 6 weeks of the start of the <br /> field work. <br /> ) <br /> k <br /> \TLEASAN ON\Admin TaLUlanIna\QuiAStop\WOR PLAN(Ge pmbe).doc 5 <br />
