r <br /> 5.0 SUMMARY AND RECOMMENDATIONS <br /> The RESNA investigation found TPH-diesel, Oil & Grease and Pesticides in one soil boring (B-=l). <br /> Some minor a2nounts of pesticides were found in 13-1 and B-2. Upgradient attempted to locate <br /> pesticide contamination outside the subject property in order to determine whether pesticide <br /> contamination is widespread withili the area or limited to the subject property. The initLal <br /> investigation on November 19 found no pesticide contamination on the adjacent properties or oil <br /> the subject property. Subsequent re-sampling near the RE,SNA sample (B-4) also found iio <br /> detectable amounts of pesticide or-petroleum contamination.- <br /> Therefore, <br /> ontamination:Therefore, Upgradient concludes that it is highly unlikely flint petroleum or pesticides pose a <br /> significant health threat at this site. The contamination found by RE SNA may have been due to <br /> laboratory error, or the samples may alive been obtained soon after the lawn areas had ben sprayed <br /> with weed hiller. We do not recominend any further investigation at this tune. <br /> G.0 REN ARILS AND SI GNATURE <br /> The recommendations contained in this report represent a professional opinion, and are'based in <br /> part on information supplied by the client.
