rf + <br /> 3 0 EXTENT OF PETROLEUM HYDROCARBONS IN SOIL AND GROUNDWATER <br /> • The results of soil sampling and analysis during soil boring and monitoring well installation <br /> and from tank and product line removal activities are summarized in Table 1 Soil samples for <br /> laboratory analysis during well installation and tank removal and replacement were collected in <br /> 1990 and 1991, whereas soil samples were collected during installation of Temporary Wells <br /> THP-1 through THP-4 in November 1994 Based on the results of these analyses, the extent of <br /> TPH-G and BTEX was limited to the vicinity of the former underground fuel tanks and <br /> associated piping to the former dispensers Soil samples have not been analyzed for MTBE <br /> During the January 2001 sampling event, petroleum hydrocarbons were detected in the samples <br /> collected from each of the five monitoring wells sampled at concentrations ranging from 400 to <br /> 19000 ug/l TPH-G Benzene was detected at a concentration of up to 14 4 ug/1 and MTBE <br /> ranged from 271 to 111000 ug/1 The results of the January 2001 analysis of groundwater <br /> samples are shown on Figure 8 <br /> I <br /> F\00\10.037\,loaedoL, 4 <br />
