TCLP stands for?

• A. Toxicity Characteristic Leeching Procedure
• B. Toxicity Characteristic Leaching Procedure
• C. Testing Characteristic Leeching Procedure
• D. Toxicity Leachate Characterization Protocol

Answer: (A)

TCLP stands for Toxicity Characteristic Leaching Procedure. This test is the EPA method used under RCRA to determine whether a waste exhibits the toxicity characteristic by leaching certain contaminants into a liquid under landfill-like conditions. The procedure simulates what could happen when waste is disposed of by extracting a representative sample with a defined leachant (an acidic acetate solution) and agitation for a specified period, then analyzing the leachate for regulated metals. If any contaminant in the leachate exceeds regulatory limits, the waste is classified as hazardous due to the toxicity characteristic. The standard term is leaching (not leeching), so the official name is the Leaching Procedure. The other options do not match the official name or the method used.
