24 May 2001 <br /> AGE-NC Project No 98-0521 <br /> Page 4 of 4 - <br /> ' * Dissolved-phase hydrocarbons including TPH-g, BTEX and MTBE, are present at <br /> significant concentrations in the sample from well MW-4, within the former UST area <br /> Hydrocarbons were encountered in the down-gradient direction from the former UST area <br /> �- to the location of monitoring well MW-2 <br /> i Additional site assessment will be required to fully assess the down-gradient extent of the <br /> ' dissolved hydrocarbons - <br /> ' 5.0. RECOMMENDATIONS <br /> Based on the results of this investigation, AGE recommends <br /> Continuation of quarterly monitoring at the site The next monitoring event should be <br /> ' scheduled for May 2001 <br /> Installation of one additional monitoring well northeast of the site to assess the lateral extent <br /> of dissolved hydrocarbons and fuel additives in ground water <br /> 1 R Preparation of a work plan addendum to delineate the vertical extent of hydrocarbon- <br /> impacted ground water <br /> 6.0. 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 <br /> geologic/hydrogeologic conditions at the site for the purpose of this investigation are made from a <br /> ' limited number of available data points (i e monitoring wells and ground water samples), and <br /> subsurface conditions may vary away from these data points No other warranty, expressed or <br /> implied, is made as to the professional recommendations contained in this report <br /> = Advanced GeoEnwronmental,Inc <br />
