Vinyl Chloride
Hepure provides zero valent iron and bioremediation products for the treatment of vinyl chloride (VC), a regulated daughter product of chlorinated solvent degradation.
About Vinyl Chloride Contamination
Vinyl chloride (VC) is a regulated contaminant classified as a known human carcinogen by the EPA. It commonly occurs as a daughter product from the incomplete reductive dechlorination of chlorinated solvents such as PCE and TCE. When parent compounds are only partially degraded through sequential pathways (PCE → TCE → cis-DCE → VC), vinyl chloride can accumulate in groundwater at concentrations that exceed regulatory standards.
Avoiding Vinyl Chloride Accumulation
One of the key advantages of Hepure’s Ferox zero valent iron products is that ZVI treats chlorinated solvents abiotically, avoiding the stepwise production of harmful daughter products like dichloroethene (DCE) and vinyl chloride. This is particularly important at sites where incomplete biological reductive dechlorination has caused VC accumulation.
Treating Existing VC Contamination
Hepure’s Ferox ZVI products can directly treat vinyl chloride through abiotic reduction pathways. For sites where biological treatment is appropriate, Hepure’s emulsified vegetable oil (EVO) and sodium lactate support complete anaerobic dechlorination to ethene and ethane. Dehalococcoides bacteria can fully degrade vinyl chloride when provided with appropriate electron donors and geochemical conditions.
Ferox Plus emulsified ZVI combines both approaches — providing ZVI for direct abiotic treatment alongside vegetable oil to support continued microbial activity.
