r <br /> ! /o <br /> + KLEiNFELDER <br /> 7 FINDINGS AND RECo&,mENDATIONS <br /> j <br /> I 7.1 SUMMARY OF FINDINGS <br /> ^� Bused on the field investigation and analytical results,the following findings are presented: <br /> o Four soul borings were drilled to a maximum of approximately 23 feet <br /> o Three ground water monitoring wells were installed to depths of approximately 24 <br /> feet. <br /> a Eight soil samples were analyzed. Total hydrocarbons were detected in soils from <br /> borings B-1 and B-2. Toluene, ethyl benzene, and xylenes were detected in soil <br /> M � <br /> J <br /> samples from boring B-2. <br /> t � - <br /> o Tbree ground water monitoring wells were purged, sampled and samples were <br /> analyzed for hydrocarbon constituents on two occasions. The ground water sample <br /> from monitoring.well MW-1 contained detectable concentrations of TPH(at 4,300 <br /> u 1 , benzene at 250 u ethyl g/) ( g/1), y benzene(at 30 ug/1),and xylenes {at 280 ug/1) <br /> (June sampling). Ground water samples from MW-2 and MW-3 were none <br /> detected for the parameters analyzed. <br /> -, - Q Ground water generally flows towards the southwest beneath the site. - - <br /> o Ground water analytical results and flow direction indicate an on-site source. t <br /> o One ground water production well was located approximately 500 yards to the <br /> southwest. This well appears not to have been in use in the recent past. <br /> o Additional on-site tanks have been removed. � <br /> �r � <br /> �yr it - <br /> .� k, a E13MUD-001.89-001 17 <br /> iy Y <br /> �y > <br /> �r c <br /> rZZ <br /> 3 <br />
