RECOMMENDATIONS <br /> Based on the findings of the environmental activities recounted in this report,AGE recommends the <br /> continuation of quarterly ground water monitoring events The next event has been scheduled for <br /> May 2005 Additionally, a sensitive receptor survey should be conducted to Identify and locate <br /> sensitive receptors,Including wells,potentially affected by the petroleum release,and to Identify and <br /> locate potential vertical conduits <br /> 10 <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 Evaluation of the hydrogeologic conditions <br /> at the site for the purpose of this investigation was made from a limited number of available data <br /> points(i e ,ground water samples)and subsurface conditions may vary away from these data points <br /> No other warranty,expressed or implied,is made as to the professional interpretations,opinions,and <br /> recommendations contained in this report <br /> Advanced GeoEnvironmental,Inc <br />
