City, California, a state <br /> certified laboratory, for TPH as gasoline and diesel and <br /> BTX&E using EPA analytical methods recommended by the RWQCB, <br /> as specified in the Tri-Regional guidelines. <br /> Analytical results will be presentc-d in tabular form, <br /> showing sample depths, results and detection limits. <br /> Analytical results will be used to delineate the vertical <br /> and lateral extent of tine contaminants in soil and ground <br /> water. A cross sectional profile will be constructed as <br /> appropriate showing subsurface lithology to depth drilled <br /> and first water table depth. <br /> 9. H drolo <br /> Ground water flow direction will be determined from survey <br /> data and water table depths. The flow direction will be <br /> shown on the site Plan. <br /> 10. Discussion and Recommendations: <br /> i Results of Phase I will be described in a technical report. <br /> e levels of contaminants in the ground water are found to . <br /> be near or below action levels, KEI. will recommend a 12 <br /> month program of quarterly monitoring and sampling to <br /> document the levels. <br /> If contaminant levels in the ground water are found to sig- <br /> nificantly exceed action levels, Phase II will be initiated. <br /> The technical .report .will be submitted .ta <br /> the <br /> ....San <br /> ..Joaquin .. <br /> Local Health District and to the RWQCB, . Central Valley <br /> Region. <br /> PHA—EI1 <br /> Phase 11 will discuss the alternatives for continuing the subsur <br /> face investigation if Phase I reveals contamination levels in the <br /> ground water significantly in excess of action levels. <br /> Phase II will include a proposal for additional monitoring wells <br /> to define a zero .line of ground water contaminat.ion.•:: It ing also <br /> propose a ground water monitoring <br /> wells installed during Phase I. and sampling. program for the <br />
