SEPTEMBER 1995 <br /> QUARTERLY STATUS REPORT (CONTINUED) <br /> • Analytical results from previous sampling events <br /> Table 3 presents a summary of the analytical results from all previous groundwater <br /> sampling events. <br /> Table 4 presents a summary of the analytical results from all previous soil sampling <br /> events <br /> • Site map delineating contamination contours for groundwater and soil based on <br /> recent data <br /> Figure 3 is a site plan that presents the analytical results from the groundwater samples <br /> collected on September 7, 1995 A "zero" line for groundwater contamination was not <br /> included in the figure because BTEX parameters were not detected in any of the <br /> samples, and TPH-D has been detected intermittently with low concentrations (130 <br /> µg/L or less, Table 3) <br /> Figure 4 is a site plan that presents a summary of the analytical results from all the soil <br /> samples collected from the site. A TPH-D "zero" line and 10-ppm line are indicated in <br /> the figure. <br /> • Estimates of the quantity of contamination remaining in soil and groundwater, <br /> and time for completing remediation <br /> Based on the results of the second supplemental site assessment, approximately 6,000 <br /> cubic yards of soil containing detectable concentrations of TPH-D are estimated to <br /> remain beneath the site. <br /> • Method of cleanup proposed or implemented to date <br /> Greyhound has submitted a work plan to PHS-EHD for a final off-site assessment and <br /> feasibility study report preparation in which a minimum of two viable soil cleanup <br /> alternatives will be evaluated <br /> • Times and dates equipment was not operating, cause of shutdown, and a <br /> corrective action plan to ensure similar shutdowns do not reoccur <br /> Not Applicable. <br /> PAMSYROIIVOLI YaA727211108969108969LO6 DOC <br /> 3 <br />
