h <br /> Former Discovery Chevrolet <br /> r `1 December 7, 1994 <br /> Environmental Labs. <br /> The groundwater sample analyzed from MW-3 contained no detectable levels of <br /> TPHg, TPHd, BTEX, or TOG. The groundwater sample from monitoring well MW= <br /> 1 had reported concentrations of TPHg and benzene at 640 parts per billion.(ppb) <br /> and 35 ppb, respectively. The groundwater sample from monitoring well MW-2 <br /> had reported concentrations of TPHg and benzene of 7,600 ppb and 370 <br /> ppb,respectively. Groundwater sample laboratory results are summarized on <br /> Table 3 and copies of chain of custody and laboratory reports are presented in <br /> Appendix E. <br /> CONCLUSIONS <br /> Based on the environmental investigations performed at the site the -following <br /> conclusions are presented: <br /> • Soil in the area of the of the former gasoline USTs is impacted with <br /> gasoline hydrocarbons. <br /> }- • Soil north of the former waste oil UST does not appear to be impacted by <br /> hydrocarbons. <br /> • Groundwater beneath and downgradient of the former gasoline USTs has <br /> been impacted by gasoline hydrocarbons. <br /> • Groundwater downgradient of the former waste oil UST does not appear <br /> to be impacted by hydrocarbons. <br /> • Gasoline hydrocarbon impacted soil . and groundwater have not been <br /> delineated in the area of the former gasoline USTs. <br /> • Lead and chromium in the soil and groundwater at the site do not appear <br /> to be present at levels warranting additional investigation. <br /> Report No. 5149701,1 6 <br /> GeoStrategies Inc. <br />
