1 <br /> Ile 6.0 CONCLUSIONS <br /> ' The following conclusions and recommendations are based on the observations and <br /> analytical data collected to date. <br /> Laboratory analysis of ground water samples indicates the presence of moderate levels of <br /> gasoline and gasoline constituents in water collected from monitoring well MW-1 and <br /> ' low levels in MW-6. All other monitoring well samples indicated non detectable levels <br /> for analyzed constituents. The data indicate a decrease in constituent levels in both <br /> monitoring wells MW-1 and MW-6 as compared with previous sampling event data. <br /> Monitoring wells MW-1, MW-2, MW-3, MW-4 and MW-8 were abandoned on June 29, <br /> 1998 in preparation for a remedial soil excavation. <br /> ' 7.0 RECOMMENDATIONS <br /> Based upon the results of the additional soil and ground water investigation, and the <br /> ' results obtained from this quarterly sampling event, AGS believes that the lateral and <br /> vertical extent of gasoline contaminated ground water-have been adequately defined. <br /> The next quarterly sampling event is scheduled for September, 1998. <br /> i 's <br /> American Geological Services,Inc. <br /> CA95DE-029 <br /> 14 <br /> 1 <br />
