Chemical Oxidation Services

Groundwater chemical oxidation involves the delivery of amendment materials to the subsurface environment to transform contaminants into less harmful chemical species. There are several different forms of oxidants, posessing widely varying properties. For instance, some amendments react instantly while others persist for long periods. Oxidant persistance is important since this affects the contact time for advective and diffusive transport and ultimately the delivery of the oxidant to the targeted zones. Care must be taken to ensure that the mobilization of certain metals does not occur due to the oxidation treatment. Treatability studies are completed prior to full-scale treatment to ascertain soil oxidant demand, oxidant efficacy on the contaminants of concern, metals speciation, and injectate concentrations.
