03 May 2000 <br /> AGE-NC Project No 95-0184 <br /> Page 4 of 4 <br />' ground water where the maximum hydrocarbon impact would be expected The lower <br /> hydrocarbon concentrations detected in samples collected from MW-1 and MW-3 may be <br />' due to this deep drowning of these wells <br /> • Ground water is currently within the screened interval in vapor well VW- <br /> 5B and near the top <br /> of the screened interval in vapor wells VW-3 and VW-4 The data collected from these wells <br />' should be representative of shallow ground water conditions in the immediate vicinity <br /> • Concentration of hydrocarbons detected at the site have generally remained stable when <br />' compared to previous monitoring events <br /> • The historical inferred ground water flow direction has generally been toward the east to <br />' southeast at the site <br />' 5.0. RECOMMENDATIONS <br /> Based upon data collected from the site, AGE recommends the following <br /> a Performance of feasibility testing and installation of additional ground water monitoring <br /> wells as proposed in Feasibility Pilot Tests Work Plan The PHS-EHD has requested further <br /> information for the performance of the feasibility testing An addendum to the work plan is <br /> currently in preparation <br />' • Continued ground water monitoring The next ground water monitonng event will be <br /> scheduled for May 2000 <br /> I <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 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 were made from a limited number of <br /> available data points (i a monitoring wells), and subsurface conditions may vary away from these <br /> data ,points No other warranty, expressed or implied, is made as to the professional <br /> recommendations contained in this report <br /> Advanced GeoEnvironmental.Inc <br />
