5.2 Analytical Results ;h <br /> The soil and ground water analytical results are summarized in'jables 2 and 3, respectively, <br /> and are discussed below. Laboratory analytical reports and chain-of-custody documentation <br /> E have been included in Appendix C. <br /> 5.2.1 Soil �I <br /> ii <br /> 1 <br /> Total Petroleum Hydrocarbons. Soil samples analyzed for TPH-D (seven samples) and <br /> TPH-G (one sample) were below the method reporting limit (MRL) of 1 milligram per <br /> P P g ) <br /> yy <br /> kilogram (mg/kg) for both constituents; however, four samples�(one sample from each <br /> boring) were found to contain low level TPH as hydrocarbon mixtures (overlapping the <br /> diesel range), with reported concentrations ranging from 2.8 to`67 mg/kg. No regulatory <br /> level has been established for TPH. , <br /> L fI <br /> Volatile Organic Compounds. All seven soil samples were analyzed for BTEX and MTBE. <br /> Toluene and xylenes, the only VOCs detected, were reported at low levels (ranging from 1.3 <br /> to 5.3 mg/kg) in samples collected from SB-01. !� r <br /> f <br /> 'll IrY <br /> ' F <br /> One it sample was`anal d for SVOCs SB-02 at 3.5 <br /> Semivolatile Organic Compounds.
