(PPM) are denoted in Table B. The concentrations are the <br /> reported values. The data from the original UST excavation <br /> report is not germane as the soil in the UST excavation was <br /> removed and clean fill was used to replace it. The highest <br /> concentration of TPHG found in the soil from the borings was 77 <br /> PPM. Therefore the TPHG values should range from a high of 77 to <br /> 0 PPM, with an average of 39 PPM. <br /> 8 . The original concentrations of contaminants for soil are the <br /> values obtained from the well construction data. The UST <br /> excavation was left open from July 1996 to November 1997 when the <br /> wells were drilled. Weathering, aeration and bioremediation <br /> occurred during that time frame. <br /> TABLE C <br /> Final concentrations of Contaminants Reported in PPM <br /> MATTER SOIL CONC WATER CONC <br /> HIGH LOW AVERAGE HIGH LOW AVERAGE <br /> TPHD NA NA NA NA 0 0 <br /> TPHG 0 0 0 0 . 0 0 0. 0 <br /> B 0. 27 0 0 . 14 . 006 0 . 003 <br /> =3 <br /> T 0 . 18 0 0 . 09 0 . 0 0 0. 0 <br /> E 0. 75 0 0 . 38 . 0011 0 . 0005 <br /> X0 , 5 <br /> 0 0 . 08 . 0001 0 . 00005 <br /> MTBE 0 0 0 . 0043 0 . 0022 <br /> 9 .

The highest, <br /> lowest and average, in parts per million, (PPM) are denoted in <br /> Table C. <br /> 10 . The values calculated are reported as significant values. <br /> 11 . No oxygenates were detected in the soil samples. <br /> B. CALCULATIONS <br />
