soil in the UST excavation was removed and clean fill was used to <br /> replace it. The highest concentration of TPHG found in the soil <br /> from the borings was 77 PPM. Therefore the TPHG values should <br /> range from a high of 77 to 0 PPM, with an average of 39 PPM. <br /> The final contamination concentrations in the soil was estimated <br /> to follow a like pattern as that reduction which occurred in the <br /> groundwater during the same period. <br /> The TPHG data in Table C was erroneously transposed and should <br /> read from a high of 20 to 0 PPM, with an average of 10 PPM. The <br /> corrected information reduces the estimated TPHG remaining in the <br /> soil at this site to 65 pounds instead of the 439 originally <br /> reported. <br /> The estimated values of TPHG and BTEX remaining in the soil is <br /> -� a:d- 0-.67 poufs respectively.- --- <br /> The calculated values of TPHG and BTEX remaining in the <br /> groundwater is 0.0, 0.0005, 0.0, 0.00008 and 0.000008 pounds <br /> respectively. The calculated values of MTBE remaining in the <br /> groundwater is 0.0003 PPM. All values are less than one part per <br /> billion. <br /> I hope that this additional information and the subsequent <br /> corrections are helpful to you. <br /> If you have questions, please call me at 510-505-0722. <br /> Sincerely <br /> Jecipal <br /> Cummings <br /> P <br /> cc:Mark List <br /> Edward P.
