Concentrations of diesel and gasoline hydrocarbons were detected in the groundwater-grab <br /> samples collected at each of the five soil boring locations The highest concentrations were <br /> detected in the groundwater-grab sample collected from SB-1, located within the former UST <br /> excavation This sample contained 2,700,000 micrograms per liter (µg/l) of TPH-as-diesel, 29,000 <br /> pg/l of TPH-as-gasoline, 68 µg11 of benzene, 7 5 µg/l of toluene, 130 µg11 of ethylbenzene, 210 pg/I <br /> of xylenes, and 6 5 µg/l of tertiary butanol MTBE, DIPE, ETBE and TAME were not detected in <br /> any of the groundwater-grab samples These groundwater-grab sample results are summarized <br /> in Table 2 <br /> Based on the results of this investigation, Ramage Environmental recommended 9 9 ended #hat three on-site <br /> ' groundwater monitoring wells be installed at the site, and that a survey of water wells within a <br /> 2,000-foot radius of the site be conducted <br /> 1 <br /> 1 <br /> i <br /> i <br /> 1 <br /> 7 <br /> i <br />
