This is one of the Federal EPA test methods that is used to characterize waste as either hazardous or non-hazardous.
The analysis simulates landfill conditions. Over time, water and other liquids permeates through landfills. These liquids often react with the solid waste in the landfill, and may pose public and environmental health risks because of the contaminants it absorbs.
What is a TCLP?
TCLP is an acronym for Toxicity Characteristic Leaching Procedure and is performed by environmental testing labs. If a solid fails the TCLP, the generator then assigns an EPA Hazardous Waste Number (Example: D008 for lead > 5 mg/L).
