Laboratory investigation of the toxicity characteristic leaching procedure and the extraction procedures test
- Dept. of the Army Waterways Experiment Station, Vicksburg, MS (USA)
The 1984 amendments to the Resources Conservation and Recovery Act (RCRA) require that the US Environmental Protection Agency (EPA) restrict the land disposal of hazardous wastes. EPA identified four characteristics that could be used to classify a waste as hazardous. These included corrosivity, ignitability, reactivity, and toxicity as defined by the Extraction Procedure Toxicity characteristic (EP). Waste exhibiting any one of these characteristics is classified as hazardous. The EP test is used to determine if a waste poses an unacceptable risk to human health and the environment. This test evaluates the potential for a waste to leach 8 metals, 4 pesticides, and 2 herbicides. The Toxicity Characteristic Leaching Procedure (TCLP) was developed to address a Congressional mandate to identify additional characteristics of wastes, primarily organic constituents, that may pose a threat to the environment. This testing procedure has been promulgated for use in determining specific treatment standards associated with the land disposal restrictions. The TCLP is also proposed as a replacement procedure for the current EP test.
