– Biogeochemical Treatment of CVOCs


Biogeochemical treatment of cVOCs has been emerging over the last decade. This process offers the promise of introducing aqueous phase reagents that react with each other in the subsurface to form reactive iron sulfides. These solid state iron-sulfides tend to create small mineral deposits with a very large surface area along the in situ flow paths. These solid state iron sulfides have the potential to persist for an extended period of time, reacting with most common cVOCs such as perchloroethylene, trichloroethylene, carbon tetrachloride and other reducable compounds. This presentation will introduce the concepts necessary to create biogeochemical conditions and provide case studies where it was used.
