�r <br /> On July 9, 1992, Resna published Summary Report—Assessment of Petroleum Hydrocarbon <br /> Contamination of the Groundwater, which documented the installation and sampling of two <br /> additional groundwater monitoring wells (MW-2 and MW-3). The monitoring well locations <br /> are shown on Figures 2 and 3, the soil sample analytical results are summarized in Table 1, <br /> the well construction details are summarized in Table 2, and the groundwater analytical <br /> results are included in Table 3. <br /> From May 8, 1992 to April 27, 1994, the three monitoring wells were monitored and sampled <br /> on three different occasions. In general, the concentrations of gasoline hydrocarbons in <br /> these wells declined; However, by April 27, 1994, the static groundwater level had risen <br /> �. above the tops of the screen intervals in all three wells. The well construction and <br /> groundwater monitoring data are summarized in Tables 2 and 3. <br /> On July 8, 1994, Resna published Summary Report/Additional Groundwater Investigation. <br /> This report documented the installation of two additional groundwater monitoring wells (MW-4 <br /> and MW-5). Gasoline hydrocarbons were not detected in groundwater collected from these <br /> two new wells. The monitoring well locations are shown on Figures 3, the soil sample <br /> �.+ analytical results are summarized in Table 1, the well construction details are summarized in <br /> Table 2, and the groundwater analytical results are included in Table 3. <br /> 1.2.3 Remediation of Source Area <br /> On June 29, 1995, Groundwater Technology, Inc. (GTI) published Environmental <br /> Assessment Report, documenting the installation of two vapor extraction well nests (VW-1 <br /> and VW-2) and two single vapor extraction wells (VW-3 and VW-4), and the pilot testing and <br /> �... modeling of soil vapor extraction. The well locations are shown on Figure 2, and the soil <br /> sample analytical results are summarized in Table 1. <br /> Based on these findings GTI recommended that the site be remediated by soil vapor <br /> extraction plus air sparging from MW-1. GTI did not implement their recommendation. <br /> L <br /> On May 20, 1998, Ramage Environmental published Problem Assessment Report and <br /> .. Corrective Action Plan (PAR-CAP)for the site. Ramage Environmental confirmed soil vapor <br /> �., extraction (SVE) and air sparging as the most efficient and practical remedial alternatives. <br /> The SVE system capture zones relative to the lateral extent of impacted soil is shown on <br /> Figure 5. <br /> � 5 <br />
