r <br /> I <br /> CONCLUSIONS <br /> Concentrations of petroleum hydrocarbon constituents decreased slightly in well MW-3 and <br /> remained at non-detect in well MW-6. It appears as though there is residual petroleum <br /> hydrocarbon contamination remaining in the soil. <br /> The direction of groundwater flow and the magnitude of hydraulic gradient are generally <br /> consistent with previous quarters. <br /> RECOMMENDATIONS <br /> Based on the results of the second quarter 1998 monitoring episode, we recommend the <br /> following: <br /> 0 Conduct the Third Quarter 1998 groundwater monitoring and sampling of wells MW-1 <br /> through MW-6. <br /> 0 Continue to analyze the groundwater samples from well MW3 for MTBE. <br /> o Discontinue analyzing the groundwater samples from all wells for oxygenate fuel <br /> additives. — <br /> Please contact our office at(209) 579-2221 if you have any questions or comments. <br /> Respectfully Submitted, ENVIRONMENTAL HEALTH DIVISION <br /> 304 E.
