Trichloroethene is listed as a priority pollutant under the Clean Water Act (CWA) and has a Safe Drinking Water Act (SDWA) maximum contaminant limit of 5 µg/L. It is regulated under the Resource Conservation and Recovery Act (RCRA) as a spent solvent process waste and as a characteristically toxic waste (any material leaching greater than 0.5 mg/L). The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) requires reporting of releases of TCE above 100 pounds (about 8 gallons), while the Superfund Amendments and Reauthorization Act (SARA) lists TCE as a chemical requiring reporting under its community right-to-know provisions. Guidance documents that address dense nonaqueous phase liquids (DNAPLS) will generally have a section that addresses TCE and other chlorinated solvents.
