PeroxyChem EHC - Model ISCR Reagent -In Situ Chemical Reduction System

EHC is composed of controlled-release carbon, zero valent iron (ZVI) particles and nutrients used for stimulating in situ chemical reduction (ISCR) of otherwise persistent organic compounds in groundwater. Following placement of EHC into the subsurface environment, a number of physical, chemical and microbiological processes combine to create very strong reducing conditions that stimulate rapid and complete dechlorination of organic solvents and other recalcitrant compounds (e.g., explosives and organochlorine pesticides).

• Stimulation of both abiotic and biotic reductive dechlorination
• Demonstrated longevity of 4-5 years in field conditions
• Combined approach minimizes the production of problematic daughter products, such as DCE and VC
• ZVI corrosion (alkaline) and fermenting carbon (acidic) are balanced producing circumneutral pHs in contrast to either alone
