Working To Restore Nature <br /> collected soil samples indicated that gasoline impacted soils are limited laterally to a relatively <br /> small area near the former gasoline fuel storage tanks, and that diesel impacted soils existed <br /> beneath the former diesel fuel storage tank to a depth of between 10 5 and 20.5 feet below <br /> ground surface <br /> ' On March 2, 1992, RESNA personnel advanced one soil boring (MW-1) to a depth of 85 feet <br /> below grade and completed it as a monitoring well Laboratory analyses of soil and <br /> ' groundwater samples collected from MW-1 indicated that groundwater and near-water soils were <br /> impacted by gasoline hydrocarbons in the vicinity of MW-1 However, groundwater samples <br /> subsequently collected from MW-1 did not contain detectable analytes <br /> ' In September 1993, the former gasoline tank pit was backfilled to ground surface by Goins <br /> Environmental Construction (A-HAZ#674281) with self-compacting material under the direction <br /> of RESNA personnel <br /> 1 Potential hydrocarbon impacted soil was excavated from the former diesel and waste oil tankP its <br /> 1 in January 1994 The excavation was performed by Goins Environmental Construction under <br /> the direct supervision of a RESNA geologist A report summarizing excavation and soil <br /> sampling activities will be submitted under separate cover <br /> ' 5.0 ADDITIONAL SUBSURFACE ASSESSMENT <br /> To further assess subsurface conditions at the site, RESNA, at the request of PHS/EHD, <br /> conducted additional field activities in October 1993 The field work was performed pursuant <br /> to the Site Safety Plan and RESNA's Quality Assurance/Quality Control Plan, Appendices A and <br /> ' B, respectively <br /> 15004718-031594 FNL 4 <br />
