EHC® Liquid is a liquid version of EHC® Reagent, specially designed for injection via existing wells or hydraulic injection networks for the treatment of a wide range of groundwater contaminants. EHC® Liquid is composed of two parts: ELS® Microemulsion, a controlled-release organic carbon substrate, and EHC® Liquid mix, an organo-ferrous compound (both food-grade). The anaerobic bioremediation processes and abiotic dechlorination reactions promoted by EHC® Liquid are effective at remediating chlorinated solvents, energetics, and pesticides/herbicides.
Typical Applications
- Direct push injection
- Gravity feed through existing wells
- Low pressure injections
- Recirculation systems
Benefits at a glance
- Stimulation of biotic reductive dechlorination through the generation of strong reducing conditions
- Structurally bound nutrients phosphorous and nitrogen released to bacteria via the fermentation of the lecithin molecule
- Direct chemical reduction from redox reaction of organoiron compound
- Surface dechlorination by magnetite and green rust precipitates from iron corrosion
- Replenished reactive iron surface provided by the cycling of iron from ferrous to ferric state in the presence of a carbon source – anticipated longevity of 2-3 yrs. depending on site conditions
- Easy to handle and cold water soluble
