What is the TCLP lead concentration limit?

Explanation:
The key idea is the threshold used in the Toxicity Characteristic Leaching Procedure for lead. In the TCLP, lead has a limit of 5 mg/L in the leachate, which is the same as 5 parts per million. If the lead concentration in the TCLP extract exceeds 5 mg/L, the waste is considered characteristic hazardous waste for lead. That’s why 5 ppm is the correct limit. The other values don’t represent the TCLP lead limit.
