Concentrations of total lead ranged from 14 ppm to 19 ppm in the four samples. <br /> Since the concentrations of total lead are relatively Iow and are consistent between the <br /> samples, this appears to be background levels of Iead. <br /> LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily <br /> exercised by environmental consultants practicing in this or similar localities. The findings <br /> were based upon analytical results provided by an independent laboratory. Evaluations of <br /> the geologic/hydrogeologic conditions at the site for the purpose of this investigation are <br /> made from a limited number of available data points (i.e. borings) and subsurface conditions <br /> may vary away from these data points. It is conceivable that petroleum hydrocarbons may <br /> exist below the depths explored. No other warranty, expressed or implied, is made as to the <br /> professional recommendations contained in this report. <br />
