KEI-P89-1104 .P2 January 10, 1950 Page 5 purgeable halocarbons using EPA method 8010, as recommended by the RWQCB, specified in the Tri-regional guidelines. Analytical results will be presented in tabular form, showing sample depths, results and detection limits. The results will be used to delineate the vertical and lateral extent of the subsurface contaminants. A cross sectional profile will be constructed as appropriate showing subsur- face lithology to depth drilled and first water table depth. Ground water flow direction will be determined from survey data and water table depths. The ground water flow direc- tion will be shown on the Site Plan. Results of Phase I will be described in a technical report. If levels of contaminants in the ground water are found to be near or below action levels, KEI will recommend a 12 month program of monthly monitoring and quarterly sampling to document the levels. If contaminant levels in the ground water are found to sig- nificantly exceed action levels, Phase II will be initiated. The technical report will be submitted to the San Joaquin County Public Health Services, and to the RWQCB, Central Valley Region. PHASE 11 Phase II will discuss the alternatives for continuing the subsurface investigation if Phase I reveals contamination levels in the ground water significantly in excess of action levels. Phase II will include a proposal for additional monitoring wells to define a zero line of ground water contamination. It will also propose a ground water monitoring and sampling program for the wells installed during Phase I. The main purpose of Phase Ii will be to establish a zero line of ground water contamination. PHASE III Once the zero line is established through the completion of Phase 11, a final remedial plan will be developed. The first step of phase III will be to conduct pumping tests to define aquifer characteristics.
