This testimony (1) presents an overview of EPA's risk assessment process that highlights where risk assumptions are made and (2) summarizes comments from reports prepared by GAO and others on some of the more controversial aspects of this process. https://www.govinfo.gov/content/pkg/GAOREPORTS-T-RCED-95-206/html/GAOREPORTS-T-RCED-95-206.htm GAO/T-RCED-95-206 https://www.govinfo.gov/app/details/GAOREPORTS-T-RCED-95-206 Testimony GAO/T-RCED-95-206; Superfund: Risk Assessment Assumptions and Issues; Hazardous substances Waste disposal Environmental monitoring Environment evaluation Evaluation methods Health hazards Information gathering operations Environmental impact statements Toxic substances Risk management Superfund Program
