11 March 2002 <br /> AGE NC Project No 95-0143 <br /> EPage 5 of 5 <br /> 6.0. RECOMMENDATIONS <br /> Based upon data collected during the February 2002 and previous sampling events, AGE <br /> recommends <br /> • Continued quarterly monitoring of the ground water monitoring well system on the site The <br /> next quarterly monitoring should be performed in May 2002, concurrent with monitoring at <br /> the Madison site <br /> • Preparation of a work plan addendum for installation of conventional vapor extraction wells <br /> to replace the horizontal vapor extraction wells and vapor extraction well VW-3 The <br /> screened Interval of VW-3 appears to have collapsed In addition, a monitoring well should <br /> I be Installed north of the site near soil boring GP-25 to further delineate the lateral extent of <br /> hydrocarbon-impacted ground water <br /> AGE is in the process of modifying the SVE system, a regenerative blower has been installed to <br /> replace the thermal/catalytic oxidenzer formerly utilized at the site The new SVE system is <br /> . anticipated to be operational within 30 days <br /> r <br /> 7.0. LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily exercised by <br /> environmental consultants practicing in this or similar localities The findings were based mainly <br /> upon analytical results provided by an independent laboratory Evaluations of the ground water <br /> conditions at the site have been made from a limited number of available data points(I e monitoring <br /> wells and ground water samples), and subsurface conditions may vary through time and with <br /> distance from these data points No other warranty, expressed or implied, is made as to the <br /> professional interpretations, opinions and recommendations contained in this report <br /> 1 <br /> i <br /> Advanced GeoEnvironmental,Inc <br />
