Both sample locations were beneath fuel dispensers (Appendix A). None <br /> of the product lines appeared to have leaked. BTEX, MTBE and PCBs were not detected in any <br /> samples. <br /> The following sections describe the steps taken to excavate, sample and dispose of the <br /> i TPH-contaminated soils encountered near the two fuel dispensers.
