18 January 2001 <br /> AGE-NC Project No 99-0592 <br /> Page 5 of 5 <br />' • TPH-g was detected in the ground water sample from monitoring well MW-1 at a <br /> concentration of 370 µg/1 The TPH-g concentration was slightly lower than the <br /> concentration detected during the Sptember 2000 sampling event _ <br />' • TPH-d was detected in the ground water sample from monitoring well MW-1 and domestic <br /> well DW-2 at concentrations of 220 p,g/l and 280 µg/l, respectively <br />' + MTBE was detected at a concentration of 7 4 µg/l in MW-1, a slight increase compared to <br /> the September 2000 sampling event <br />' None of the target analytes were detected in the ground water sample collected from <br /> domestic well DW-1 <br /> 5.0. RECOMMENDATIONS <br />' Based on the results of this investigation, AGE recommends <br /> • Continued quarterly monitoring of monitoring well MW-1 _ <br /> • Continued sampling and analysis of domestic well DW-1, currently in use on-site The <br /> samples should be analyzed for TPH-g, BTEX, fuel oxygenates by EPA Methods noted <br />' above <br /> t <br />' 60. 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 upon ' <br /> analytical results provided by an independent laboratory Evaluations of the geologic/hydrogeologic <br />' conditions at the site for the purpose of this investigation are made from a llnuted number of <br /> available data points (I a monitoring well ground water samples) and subsurface conditions may <br />' vary away from these data points No other warranty, expressed or implied, is made as to the <br /> professional recommendations contained In this report <br /> 1 3 <br /> Advanced Geoltnvironmental,Inc <br />
