i 16 July 20o 1 - <br /> AGE-NC Project No 95-0135 <br /> Page 4 of 4 " <br />' wells MW-1 and MW-2 <br /> The fuel additives DIPE and MTBE were detected on the site MTBE was detected at <br /> concentrations exceeding the State of California maximum contaminant level in sample <br /> MW-2B at 20 µg/l <br /> I ' <br /> 5.0. RECOMMENDATIONS ' <br />' Based on the results of this and previous investigations, AGE recommends <br />' • Continued quarterly monitoring of the site The next monitoring event should conducted in <br /> July or August 2001 <br /> • Additional assessment of the lateral extent and vertical extent of hydrocarbon-impacted soil <br />' north of the former UST area and in the area of well MW-1 <br /> Additional assessment of the lateral extent of impacted ground water south of the former <br /> lie <br /> UST area and north and west of well MW-1 and vertical assessment in the MW-1 and MW--2 <br /> area <br /> O Once the impact to soil and ground water impact has been delineated, a work plan should be <br /> prepared for feasibility testing to evaluate various remedial alternatives at the site <br /> 6.0. LIMITATIONS <br /> 4 ` <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 on <br /> analytical results provided by an independent laboratory Evaluations of the geolognc/hydrogeolognc <br /> conditions at the site for the puzpose of this investigation are made from a limited number of <br /> available data points (i e ground water samples) and subsurface conditions may vary away from <br /> these data points No other warranty, expressed or implied, is made as to the professional <br /> recommendations contained in tins report <br /> F <br /> Advanced GeoEnvironmental,Inc <br />
