The groundwater samples collected from MW-2, MW-4 and MW-6 contained dissolved <br />' concentrations of gasoline compounds The groundwater analytical results are summarized in <br /> Table 3, the distribution of TPH-as-gasoline, benzene and MTBE in groundwater is shown on <br /> separate isoconcentration maps (Figures 5, 6, and 7) and the laboratory reports are included in <br /> Appendix A <br /> u <br /> 23 Free Product Removal <br /> On March 7, 2003, Ramage Environmental installed a Hydro-SkimmerT" passive free product <br />' skimmer in MW-1 The passive skimmer is four-inch diameter and 64-inches long, with a 10-inch <br /> recovery zone <br /> Between March 7, 2003 and June 9, 2004, after 25 site visits, approximately 96 08 ounces of <br />' accumulated free product has been removed from the skimmer During this time, the free product <br /> thickness has been reduced from 0 45-foot to a sheen less than 0 01-foot Each of the free <br /> product removal events is summarized in Table 4 <br /> 2.4 Waste Soil Disposal <br /> Waste soil generated in December 2003, during the drilling of MW-4, MW-5 and MW-6, was <br /> contained in 11, 55-gallon drums and stored on-site pending characterization, and proper <br /> disposition Three drums of waste soil cuttings generated in November 2001 from the installation <br /> of MW-3 also remained on-site <br />' On December 2, 2003, Ramage Environmental collected a soil sample from every third drum for <br /> laboratory composite and analysis Excelchem combined the five soil samples into one, and <br /> analyzed the composite soil sample for TPH-as-gasoline and BTEX by EPA Method 8020/8015M, <br /> and for total lead by EPA Method 6010B <br />' The composite soil sample only contained 0 016 milligrams per kilogram (mg/kg) of total xylenes <br /> and 4 6 mg/kg of total lead The laboratory report is included in Appendix A Based on these <br /> tanalytical results, Ramage Environmental profiled the waste sod as non-hazardous waste, for <br /> disposal at Forward Landfill in San Joaquin County, under Approval #4049 On March 24, 2004, <br /> MB Environmental loaded the 14 drums of waste sod onto a truck, and transported the waste to <br /> Forward Landfill for disposal Copies of the non-hazardous waste manifest and landfill weight <br /> ticket are included as Appendix B <br /> 6 <br />
