Toxicity Characteristic Leaching Procedure (TCLP)

The Toxicity Characteristic Leaching Procedure (TCLP) is a testing method used to determine if certain wastes are hazardous. It simulates how a waste might release dangerous substances when disposed of in a landfill by soaking the waste in a liquid that mimics landfill conditions. If harmful chemicals leach out in significant amounts, the waste is classified as hazardous, ensuring proper management and environmental protection. This process helps regulators identify and control waste that could pose risks to human health and the environment.
