Site Applicability

Groundwater contaminants treated using ISCO technology includes 1,4-dioxane TCE, PCE, DCE, TCA, DCA, methylene chloride, vinyl chloride, BTEX, MtBE, gasoline, diesel fuel, and many other difficult to treat organic constituents. The chemical oxidants can be injected through dedicated injection wells or by direct push rigs Properties that must be cleaned up in a relatively short time frame (i.e., property transactions) or those that have groundwater pump and treat systems operating for extended periods of time are most appropriate for chemical oxidation treatment. Chemical oxidation is a very cost-effective alternative to other methods of groundwater treatment. Treatment using chemical oxidation can be completed within six months or less and can achieve reductions in contaminant levels from 85% to 100%. Potassium permanganate (KMnO4) is effective on chlorinated ethenes (such as PCE, TCE, and DCE) and is typically the first chemical oxidant to consider, since it is the most persistent oxidant and can be delivered to a larger radius of influence. Hydrogen peroxide and persulfate are stronger, more aggressive oxidants and they should be used on more difficult contaminants. Peroxide and persulfate must be activated by a catalyst and produce free radicals, which are powerful oxidants that effectively treat most all VOC compounds.

Bench Scale Treatability and Pilot Testing

JAG Consulting Group provides services for the design and implementation of Bench Scale Treatability tests which involves testing of groundwater and saturated soil to evaluate contaminant destruction potential and determine the dosage rates for various activation agents. The knowledge learned from a successful pilot scale test can be applied for full-scale treatment of the entire site. The measured radius of treatment from the pilot test can be used to select additional wells or injection locations during full-scale treatment to ensure that the entire groundwater plume is effectively treated.
