RECOMMENDATIONS ' <br /> I <br /> Based upon the data collected to date,AGE recommends ` <br /> • Continued quarterly monitoring, the next quarterly'ground water sampling and monitoring <br /> event should be scheduled for March'1999 <br /> • Installation of an additional ground water monitoring well approximately 35 feet southeast <br /> of VW-1 near the Inferred southern margin of the dissolved plume <br /> • Installation of two additional deep aquifer zone ground water monitoring wells, with depth- <br /> discrete well screens Grab water samples should be collected at a depth of approximately ! <br /> I 45 feet bsg from the borings advanced for the well Installations to aid in definition of the, I <br /> apparent down-gradient extent of shallow dissolved hydrocarbons These samples should be w <br /> analyzed for the same coristituents as the proposed ground water monitoring well network <br />' • _ Installation of additional soil vapor extraction and/or in-situ air sparging wells needed for i <br /> F <br /> active remediation at the site <br /> I f <br /> 6.0.
