TOXICITY CHARACTERISTIC LEACHING PROCEDURE (TCLP)

A test that measures the mobility of organic and inorganic chemical contaminants in wastes. The test, designed by the U.S. Environmental Protection Agency (EPA), produces an estimate of the potential for Leachate formation by a waste if it is placed in the ground. If the TCLP is applied to a solid waste sample and the extract leached from the waste or the solid waste sample itself contains concentrations of specified materials exceeding allowable levels, the waste is defined as a Hazardous Waste, meeting the toxicity characteristic.
