Project No 102 2 <br /> December 19,2001 <br /> 3.0 DISCUSSION <br />' 3.1 Discussion of Data <br />' <br /> Field and analytical data results are summarized n Tables 1 and 2 and <br /> illustrated In Figures 3 through 5 <br /> The map of groundwater gradient (Figure 3) suggests that the flow of <br /> groundwater is to the northeast The water table has fallen about 3 feet since <br /> the last monitoring event in June of 2001 The direct ion and gradient of flow <br />' have remained generally consistent over the entire time the wells have been <br /> monitored <br />' In general, the analytic data suggest that contamin int levels are gradually <br /> decreasing except in the area of MW-811 and MW-7, near the core of the plume <br />' It appears that the lateral extent of the contaminant plume may also be <br /> gradually decreasing The wells MW-10 and MW-11, .Lt the distal periphery of <br /> • the plume have been producing samples with essentially non-detectible levels to <br />' petroleum contaminants <br /> 3.2 Future Work Schedule <br /> Quarterly groundwater monitoring and sampling should continue Recently, <br /> Geo-Phase Environmental submitted a Work Plan that proposed pilot level <br /> remedial work to investigate possible methods to achieve an adequate level of <br /> mitigation of this site The Work Plan has been approved by the LOP agency, <br /> and a detailed budget covering the work is being prepared for submission to the <br /> IState UST Clean-up Fund for pre-approval of the associ ited costs <br /> i <br /> lie <br /> 2937 Veneman Ave ,#B240 Geo-Phase Environmental Inc Phone (209) 569-0293 <br /> Modesto, CA 95356 Fax (209) 569-0293 <br />
