4.1.5 Volatile Organic Compounds <br />Acetone is the only Volatile Organic Compound (VOC) detected in Parcel III soil samples. <br />Acetone was detected at 180 jig/Kg in the capillary fringe sample collected from MW-4 (MW-4B/10.0). <br />Comprehensive laboratory data reports are included in Appendix B. <br />VOCs were not detected in samples collected from near surface soils. Acetone is occasionally <br />used as a laboratory solvent and is commonly used in the paint and plastic industry. <br />The State of California Environmental Protection Agency, Department of Toxic Substances <br />Control (DTSC) adopts the numerical standards set under RCRA for identifying and listing materials as <br />hazardous waste in Title 22 of the California Code of Regulations (CCR). The numerical standard for <br />acetone in the Lists of RCRA Hazardous Wastes from Non-Specific Sources is 590 p.g/Kg (22 CCR, <br />66261.31). The detection of acetone in the capillary fringe in Parcel III is below the numerical standard <br />for hazardous waste as defined in Title 22. <br />4.1.6 Semi-volatile Organic Compounds <br />Semi-volatile Organic Compounds (SVOCs) were detected in all four soil samples submitted for <br />analysis from Parcel III. SVOC detections are presented in Table 3. Comprehensive laboratory <br />analytical data reports are included as Appendix B. <br />SAC28.013 <br />12 <br /> December 20, 1991 <br />DAMES ,St 70.04 -)p.r
