l26 December 2000 <br /> AGE-NC Project No 97-0300 <br /> Page 4 of 4 <br /> and the September 2000 ground water monitoring events (Table 1) The decrease of ground <br /> water elevations is probably due to the seasonal fluctuation pattern <br /> • Very low concentrations of dissolved TPH-d appear to be present in the area of monitoring <br /> well MW-1 indicating that there is only a minor impact to ground water in the area assessed <br /> 5.0. RECOMMENDATIONS <br /> Based upon the results of the Third Quarter 2000 investigation, AGE recommends <br /> • Continued Quarterly ground water monitoring of wells MW-1, MW-2 and MW-3 for the <br />' remainder of the year, following four consecutive ground water monitoring events,AGE will <br /> make a recommendation to the PHS-EHD to re-evaluate the ground water monitoring <br /> program, if warranted The next ground water monitoring event is tentatively scheduled for <br /> IDecember 2000 <br /> • Submission of a ground water monitoring well sample collected from MW-1 to a <br /> microbiological laboratory for microbial enumeration and physicochemical analysis to assess <br /> the potential for natural attenuation of petroleum hydrocarbons in ground water at the site <br /> • Elimination of analysis for methanol, ethanol, 1,2-DCA and EDB in collected ground water <br /> samples <br /> • Preparation of a corrective action plan report to evaluate several remedial alternatives for the <br /> site <br /> G.O. 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 geologic/hydro- <br /> geologic conditions at the site for the purpose of this investigation are made from a limited number <br /> of available data points (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 this report <br /> Advanced GeoEnvi ron mental,Inc <br />
