ame0 <br />Ms. Margaret Lagorio <br />San Joaquin County Environmental Health Department <br />August 6, 2008 <br />Page 3 <br />A Health and Safety Plan will be prepared. A tailgate health and safety meeting <br />will be held before any work begins on Site <br />All borings will be advanced using direct push technology, which is described in <br />Appendix A. Three 20-ft boreholes will be advanced; B-1, B-2, and B-3 (Figure <br />2). Borings will be continuously cored for soil logging using the Unified Soil <br />Classification System (USCS) as described in ASTM International Standard <br />D2488. <br />Grab groundwater samples will be collected from borings B-2 and B-3 to assess <br />shallow groundwater impacts associated with the leaking farm tanks (Figure 2). <br />Groundwater sampling procedures are described in Appendix B. Groundwater <br />samples will be submitted for laboratory analysis by EPA method 350.1 for <br />ammonia, and EPA method 9040B for pH. Samples will also be collected for <br />field testing of pH. <br />A soil sample will be collected at boring B-1 to access soil impacts associated <br />with the soil staining near the railroad spur (Figure 2). Soil sampling procedures <br />are described in Appendix A. The soil sample will be analyzed by EPA method <br />8015 B Modified for Total Petroleum Hydrocarbons (motor oil range) and EPA <br />method 6010B for lead and arsenic. <br />Quality Assurance and quality control (QA/QC) will consist of a trip blank <br />included in the sample cooler which will be analyzed for TPH by EPA 8015B. <br />Laboratory reports will be reviewed for further QA/QC by a qualified professional. <br />Following sampling, each borehole will be backfilled with neat cement and <br />completed to surface grade (Appendix C). <br />All soil cuttings and drilling water will be contained in labeled drums and stored <br />on Site pending laboratory analysis. <br />Please feel free to contact the undersigned if you have any questions.
