Under TCLP, what is the acceptable lead concentration in ppm?

• A. 1 ppm
• B. 0.5 ppm
• C. 5 ppm
• D. 10 ppm

Answer: (C)

Under TCLP, the lead limit in the leachate is 5 mg per liter, which is equivalent to 5 ppm in water. This means that if the leachate from a waste sample contains more than 5 mg/L of lead, the waste would fail the TCLP test and be considered hazardous for lead. The values 1 ppm and 0.5 ppm are stricter than the federal limit, and 10 ppm is looser than the limit, so they don’t represent the regulatory threshold.
