LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily exercised <br /> by 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(e g ,groundwater 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 />
