■ <br />Y <br />DECEMBER 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 December 5, 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 />µglL 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 will implement the recently approved "Offsite Assessment and Feasibility <br />Study" work plan, dated September 1995. A feasibility study report in which a <br />minimum of two viable soil cleanup alternatives are evaluated will be submitted <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 />• <br />PARESSYR011VOLi wP1727211108969108969L06 DOC <br />3 <br />
