7hN3dweII&RoIIo <br /> • <br /> 4.1.3 Treatment <br /> Three variations of soil treatment were initially screened, including stabilization and fixation <br /> with cement, in situ treatment by biodegradation or vacuum extraction, and thermal treatment via <br /> steam stripping or the use of a rotary kiln. While none of these options are acceptable for both <br /> organic and inorganic contamination, biodegradation and vacuum extraction are known to <br /> remediate certain petroleum and halogenated hydrocarbons. These technologies are retained for <br /> consideration. Vacuum extraction is being used at Area 16 to remediate hydrocarbon <br /> contamination in soil. <br /> 4.2 Comparison of Soil Remedial Alternatives <br /> Table 5 summarizes the comparison of the No Action, Containment, and Removal remedial <br /> alternatives, using the nine evaluation criteria listed in the DTSC RAP outline. The Evaluation <br /> Criteria are: <br /> • 1. <br /> Overall protection of human health and the environment <br /> 2. ARAR compliant <br /> 3. Long-term effectiveness <br /> 4. Short-term effectiveness <br /> 5. Reduction in toxicity/mobility/volume <br /> 6. Implementability <br /> 7. Regulatory acceptance <br /> 8. Community acceptance <br /> 9.
