DECEMBER 1993 BIANNUAL STATUS REPORT (CONTINUED) • Analytical results of groundwater or soil sampling: Results of the December 1993 biannual sampling event are summarized in Table 2. None of the analyzed parameters were detected in any of the samples t • A site map showing the "zero line" of contamination, and changes in analyses and gradient measurements over the last quarter: ? A "zero line" for groundwater contamination has not been mapped because none of the analyzed parameters were detected in the groundwater samples collected during the December 1993 samphng event (Table 2). • 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 for all of the monitoring wells located at the facility are presented in Table 1. • A site map delineating groundwater elevation contours based on recent data: Groundwater elevations determined by water level measurements made on December 7, 1993 suggest a southerly groundwater flow direction under a very low hydraulic gradient (Figure 2) • 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 LML M823 221004 R3 3
