Evaluation of Soil Amendment Technologies at the Crooksville/Roseville Pottery Area of Concern STAR Organics Soil Rescue. Innovative Technology Evaluation Report

摘要

Star Organics, L.L.C., of Dallas, Texas (Star Organics), has developed Soil Rescue to treat soil contaminated with metals. Star Organics claims that Soil Rescue forms metal complexes that immobilize toxic metals, thereby reducing the risk to human health and the environment. The Superfund Innovative Technology Evaluation (SITE) Program evaluated an in situ application of the technology during a demonstration at two lead contamination sites in Roseville, Ohio, in September 1998. For the demonstration, Soil Rescue was applied to 10 experimental units at a trailer park and one experimental unit at an inactive pottery factory. Primary objective 1 (P1) was to evaluate whether Soil Rescue can treat soil contaminated with lead to meet the Resource Conservation and Recovery Act (RCRA)/Hazardous and SolidWaste Amendments (HSWA) alternative universal treatment standards (UTS) for land disposal of soils contaminated with lead. Primary objective 2 (P2) was to evaluate whether Soil Rescue could decrease the soil lead bioaccessibility by 25 percent or more, as defined by the Solubility Bioaccessibility Research Consortiums (SBRC) Simplified In- Vitro Test Method for Determining Soil Lead and Arsenic Bioaccessibility (simplified in vitro method (SIVM)). However, EPA Lead Sites Workgroup (LSW) and Technical Review Workgroup for lead (TRW) at this time, do not endorse an in-vitro test for determining soil lead bioaccessibility (Interstate Technology and Regulatory Cooperation (ITRC) 1997). To meet objective P2, soil samples were collected before and after the application of Soil Rescue.
