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 mainly based <br /> upon analytical results provided by an independent laboratory Evaluations of the geologic <br />' conditions at the site have been made from a limited number of available data points (i e sampling <br /> points, monitoring well, etc), and subsurface conditions may vary away from these data points No <br /> other warranty, expressed or implied, is made as to the professional recommendations contained in <br />' this report <br /> f i <br /> J <br /> 1 n <br /> i <br />
