5 2 GROUND WATER SAMPLES <br />' The ground water samples were tested for TPH-G using modified EPA Method 8015, <br /> BTXE using EPA Method 602, and purgeable halocarbons using EPA Method 601 The <br /> results of the testing are shown on Table 4 The laboratory reports are contained in <br /> Appendix E. <br /> 6.0 DISCUSSION <br /> 1 <br /> 6 1 SOIL <br />' The analytical testing results of the soil samples obtained from borings drilled as part <br /> of this investigation show that TPH-G concentrations ranging from 6.9 to 3,110 ppm were <br /> encountered The highest concentrations of TPH-G were detected in samples collected <br /> from boring location MW-2 at depths ranging between 20 and 60 feet bgs Elevated <br /> concentrations also were detected in the samples collected from borin B-11 between 40 <br /> and 50 feet bgs TPH-G was detected only in only one sample (MW-1 9a 45 feet) collected <br /> from boring MW-1. BTXE also were detected in many samples. Several chlorinated <br /> hydrocarbons not associated with gasoline were detected at selected sample locations, e g , <br /> tetrachloroethene (PCE), trichloroethane (TCE), and 1,1,1-tnchloroethane (1,1,1-TCA). <br /> The source of these chlorinated hydrocarbons is unknown. <br />' 6 2 GROUND WATER <br /> TPH-G, BTXE and 1,2-dichloroethane were detected in the ground water samples <br /> collected from the wells The benzene and 1,2-dichloroethane concentrations detected in <br /> the water samples collected from the wells exceed the action levels established by the state <br /> for drinking water. <br /> 7.0 LIMITATION <br /> Our professional services have been performed using that degree of care and skill <br /> ordinarily exercised, under similar circumstances, by reputable environmental consultants <br /> practicing in this or similar localities This report has been prepared for Montgomery <br /> Ward No other warranty, expressed or implied, is made as to the professional advice <br /> contained in this report. <br /> Project No. 1232 7 ENVIRONMENTAL AUDIT,INC® <br />
