The Report <br /> evidences petroleum contamination in the soil 7.5 feet below surface grade(bsg)in the location <br /> of the west dispenser(boring#HA1). Further investigation to determine the lateral and vertical <br /> extent of soil contamination in this area is necessary. PHS/EHD agrees with the <br /> recommendations in the Report to construct a minimum of one, soil boring in the area of boring <br /> #HAL Soil samples should be collected every 5 feet bsg,or at every significantly different <br /> lithological change until at least two consecutive soil samples,are non-detectable for <br /> t contamination. <br /> A minimum of at least one groundwater sample must be collected in the location of boring HA#1. <br /> Analyze soil and groundwater samples for total petroleum hydrocarbon(TPH)as gasoline and <br /> TPH as diesel using EPA Method 8015;benzene,toluene, ethylbenzene, and xylene using EPA <br /> Method 8020; oxygenates, 1,2 dichloroethane, ethlylene dibroinide,ethanol and methanol using <br /> EPA Method 8260. If groundwater contamination is evidenced,the borehole should be converted <br /> into a monitoring well and quarterly groundwater monitoring should be initiated at the site. <br /> q <br /> A Work Plan to further evaluate the lateral extent of soil and Qroundwater contamination at this = <br /> site must be submitted to PHS/EHD by November 2, 2000.
