Cooperative Testing of Municipal Sewage Sludges by the Toxicity CharacteristicLeaching Procedure and Compositional Analysis

摘要

The Toxicity Characteristic Leaching Procedures (TCLP) is a testing proceduresthat has been developed by the Office of Solid Waste (OSW) for determining whether or not solid wastes, including Municipal sewage sludges, are hazardous based upon toxicity. The procedure was a proposed replacement for the Extraction Procedure (EP), used for the purpose since 1980. In the TCLP, the concentrations of analytes in the extracts are compared to Toxicity Characteristic (TC) regulatory levels. If concentrations of analytes in the TCLP extract meet or exceed these regulatory levels, the wastes are classified as hazardous.
