No levels of BTX above the analyses method <br /> detection limit of 1 .0 ppm were found . Samples retained for <br /> laboratory analyses from soil boring 2 , at the 30-foot level and <br /> boring 3, at the 34-foot level yielded no concentrations of THC or <br /> roc BTX above the 1 .0 ppm detection limit. <br /> Water samples were obtained on March 19, 1987, for analysis <br /> of THC and BTX by GT Environmental Laboratories using a modified <br /> a <br /> EPA Method 602 . The results of these analyses are presented in <br /> Table 2 , Water Sample Analysis Summary (see Appendix III for <br /> laboratory results) . <br /> krr <br /> r • <br /> !wn <br />
