DECEMBER 1994 QUARTERLY STATUS REPORT (CONTINUED) 2 Changes in analytical results and groundwater elevations are indicated in Tables 1 and 3 Figure 4 is a comprehensive soil analytical data map which includes data from all soil samples collected to date A TPH-D "zero" line and 10 ppm line are also indicated on this site plan • Tabulated data for all monitoring wells including groundwater elevations collected to date: The physical data collected during the preliminary site investigation and subsequent groundwater sampling events are summarized in Table 1 • A site map delineating groundwater elevation contours based on recent data: Groundwater elevations based on water level measurements made on December 19, 1994 suggest a southerly groundwater flow direction under a low hydraulic gradient (Figure 2) A contour map of groundwater elevations was not prepared because the elevations measured in the three wells differ by 0 30 feet or less • Analytical results from all previous sampling events including laboratory reports for the most recent sampling event and chain-of-custody documentation: A summary of the analytical results from all previous groundwater sampling events is presented in Table 3 A summary of the analytical data for all soil samples collected to date is presented in Table 4. The laboratory results from the most recent groundwater sampling event, and chain-of-custody documentation are provided in Appendix A • Site map delineating contamination contours for soil and groundwater based on recent data: A site map showing analytical results and contamination contours from soil samples collected during all previous site investigations, including the most recent Supplemental Site Assessment, is included in Figure 4 A map delineating the extent of groundwater contamination has not been prepared because BTEX parameters were not detected in any of the samples and PARESSYROMOL1 WP1725218108969108969LO7 DOC R2 4
