Reductive stabilization of CCA metals - Bench test

Start date: Oct 1st, 2014
Finish date: Dec 15th, 2015

Bench tests were performed to evaluate the Site-specific performance of two different types of reducing agents and treatment processes: 1) Abiotic chemical reduction using calcium polysulfide and ferrous sulfate, and 2) biotic reduction using lactate and ferrous sulfate. The specific objectives of bench tests were:

  • Measure the effectiveness of test amendments on treatment of CCA metals, and
  • Identify the most effective treatment agent(s) for potential future pilot-scale tests.
