Superfund sites contain numerous similarities with respect to hydrogeologic conditions, type and nature of contamination, and social impacts. From these similarities, US EPA has developed a proactive framework using presumptive remedies, or preferred common technologies to streamline and accelerate the remediation process. This proactive framework is termed the Superfund Accelerated Clean Up Model (SACM). The SACM and presumptive remedy approach was successfully applied to the over 300-acre Phoenix-Goodyear Airport (PGA) Superfund site in Goodyear, AZ to remediate trichloroethylene-contaminated soils. Soil vapor extraction (SVE) was selected as the presumptive remedy of choice. Acceleration of the PGA remediation process was accomplished through the combined use of a comprehensive soil vapor program and use of the vadose zone contaminant transport models VLEACH and MixCell. The models were used to develop groundwater-risk based soil clean up levels for TCE using soil vapor data. The models were then used for site prioritization, remedial design and operation and site closure. This innovative approach and the VLEACH and MixCell models have withstood intense scrutiny and have been included in several subsequent Superfund Records of Decision (RODs) and Consent Decrees. Application of the SACM has allowed the PGA site to progress from conceptual design to full-scale operation and closure of the first treatment area in under 3 years. Significant cost savings have been realized in reduced investigation, pilot testing, design and monitoring efforts at the site.
