US EPA 1311 - Toxicity Characteristic Leaching Procedure (TCLP)

SGS has years of experience providing practical Acid Rock Drainage (ARD) solutions to the mining industry. We have a comprehensive range of ARD testing capabilities including the US EPA 1311 test Toxicity Characteristic Leaching Procedure (TCLP).

The Toxicity Characteristic Leaching Procedure (TCLP) determines the mobility of inorganic contaminants present in a sample and whether the leachates generated would classify the material as "hazardous". The leachant is determined based on the acid neutralization capacity of the sample material. The selected leachant is added to the sample at a 20:1 liquid-to-solids ratio and the sample container is rotated end over end for 18 hours. The resultant slurry is then filtered through a 0.7 µm glass fiber filter and analyzed for total metals.

SGS has developed a reputation as an organization that has the tools and experience to handle ARD testing. Partner with us to be confident that you completely understand the scope of your ARD situation.
