KEI-P88-0810.W2 <br /> May 5, 1989 <br /> Page 4 <br /> Analytical results will be used to delineate the vertical <br /> and lateral extent of the 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. Hydrology: <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 /> Results of Phase I will be described in a technical report. <br /> If 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 to the San Joaquin <br /> Local Health District and to the RWQCB, Central Valley <br /> Region. <br /> PHASE II <br /> Phase II will discuss the alternatives for continuing the subsur- <br /> face investigation and or remediation if Phase I reveals con- . <br /> tamination levels in the ground water significantly in excess of <br /> action levels.. <br /> Data Anal ses and Report Preparation <br /> _The _data -gathered __during the--course-- of -investigation_will be. - <br /> - - - evaluated and a .report prepared. Also, items specifically` <br /> requested by the RWQCB in their April 17, 1989 letter will be <br /> included:. The report will present an assessment of the extent <br /> and concentration of chemicals detected in the sampled area. The <br /> report will include detailed descriptions of the methodologies <br /> used. to collect and analyze data, the interpretations of such <br /> data, and the technical rationale for the conclusions reached. <br />
