RECOMMENDATIONS <br /> Based upon data obtained during the third quarter of 2002 and previous sampling events, AGE <br /> 1 recommends <br /> • Continued quarterly monitoring of the site The next quarterly monitoring event should be <br /> ' scheduled for December 2002, concurrent with monitoring at the former Chase Chevrolet <br /> Van Buren site <br /> • Preparation of a Final Remediation Plan to address hydrocarbon-impacted ground water near <br /> ' the former UST No 8 <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 mainly <br /> upon analytical results provided by an independent laboratory Evaluations of the hydrogeologic <br /> rconditions at the site have been made from a limited number of available data points (i a ground <br /> water monitoring wells, ground water samples) and subsurface conditions may vary through time <br /> and with distance from these data points No other warranty,expressed or implied,is made as to the <br /> ' professional interpretations, opinions and recommendations contained in this report <br /> ' Advanced GeoEnvironmental,Inc <br /> 1 <br />
