What Does TCLP Stand For?

TCLP stands for Toxicity Characteristic Leaching Procedure

The Toxicity Characteristic Leaching Procedure (TCLP) is a standardized testing method used to determine the potential leachability of hazardous substances from solid waste materials. It assesses whether waste can release toxic contaminants into the environment when subjected to leaching conditions, helping to identify materials that may be classified as hazardous under regulatory frameworks. The TCLP is critical for landfill compliance, waste management practices, and environmental protection efforts.
