In-situ geochemical fixation using a chemical reductant such as Remotox (calcium polysulfide) converts the soluble toxic metals into insoluble non-toxic compounds. Remotox has proven to be effective under a wide range of conditions. It is considered more stable and persistent than other reductants in subsurface environments, and is relatively safe to handle in the field and easy to apply.
