FINDINGS <br />Twenty soil samples collected during the August 2018 investigation were analyzed for <br />one or more of the constituents listed in Section 4.2. The following is a summary of the <br />analytical results. <br />• TPH-d was detected in a total of nine (9) soil samples. TPH-d was detected in <br />samples SW -E, S5-2, S6-2, S6SW-S, SP -1, SP-2/SP-3, and SP -4 at <br />concentrations ranging between 21 mg/kg in SW -E and 1,460 mg/kg in S6-2. <br />Additionally, TPH-d was detected in samples B-5 and S12-2 at concentrations of <br />11.6 mg/kg in B-5 and 10.9 in S12-2, just above the laboratory detection limit of <br />10 mg/kg. The ECI laboratory reports contained the following comment/lab note <br />for every TPH-d detection: Peaks in diesel range but chromatogram does not <br />match that of diesel standard. <br />• TPH-mo was detected above the laboratory reporting limit of 50 mg/kg in a total of <br />seven (7) soil samples. TPH-mo was detected in samples SW -E, S5-2, S6-2, <br />S6SW-S, SP -1, SP-2/SP-3, and SP -4 at concentrations ranging between <br />
