• TABLE 3 <br /> SEMI VOLATILE ORGANIC COMPOUNDS (SVOCs) IN SOIL <br /> EPA METHOD 8270 <br /> 9 Detections only - mg/Kg (ppm) <br /> BORING DEPTH SAMPLE I.]D- COMPOUNDS DETECTED <br /> 1 <br /> MW-1 0.5 MW-113/0.5 Di-n-Butyl Phthalate - 0.87 mg/Kg <br /> MW-1 10.0 MW-lA/10.0 Di-n-Butyl Phthalate - 0.63 mg/Kg <br /> y <br /> MW-4 0.5 MW-413/0.5 Di-n-Butyl Phthalate - 0.42 mg/Kg <br /> Fluoranthene - 0.21 mg/Kg <br /> Pyrene - 0.24 mg/Kg <br /> MW-4 10.0 MW�B/10.0 Di-n-Butyl Phthalate - 0.75 mg/Kg <br /> As illustrated in Table 3, Di-n-Butyl Phthalate was detected in all four samples analyzed ranging <br /> from 0.42 to 0.87 mg/kg. The four samples analyzed were submitted to the analytical laboratory in one <br /> batch. For this sample batch, the laboratory performed analysis of a method blank. Di-n-Butyl Phthalate <br /> was detected in the method blank at a concentration of 0.60 mg/kg. The detection of this compound in <br /> F• the method blank suggests that the presence of Di-n-Butyl Phthalate in soil samples are probably not <br /> valid, and are likely due to laboratory error. <br /> Floranthene and pyrene are compounds commonly associated with wood treatment facilities. The <br /> Phase 1 investigation did not identify any historical wood treatment operations on the site (Dames & <br /> Moore, 1991). The DHS numerical standards as stated in the lists of RCRA Hazardous Wastes from <br /> Non-Specific Sources under the waste code for leachate resulting from the treatment, storage, or disposal <br /> of wastes is 8.2 mg/Kg for both fluoranthene and pyrene (CCR, 1991). The detections of these <br /> compounds in soil samples from Parcel III are well below this numerical standard. <br /> 4.1.7 Elemental Sulphur <br /> Elemental (total) sulphur was detected in all three samples analyzed. Sulphur detections are <br /> presented in Table 4. Comprehensive laboratory analytical data reports are included in Appendix B. <br /> 1� <br /> SAC28.013 December 20, 1991 <br /> 13 <br />
