The Adventus Mercury Removal Advantage
Responsible environmental experts in the academic, business and regulatory communities are increasingly more worried about the high levels of mercury contamination affecting many parts of the world. The international community is focusing their attention on this growing problem and EHC-M will clearly help, as it is perfectly suited for treating environments co-impacted by both heavy metals and chlorinated solvents. A recent study showed greater than 99 percent removal of total mercury from groundwater was achieved with EHC-M. Impressive as this is, there are also remarkable cost differences between EHC-M and other products on the market such as Regenesis' MRC . Low redox, high organic content and zero valent iron promotes the reduction of mercury, chromium and other heavy metals potentially dangerous to public health and the environment. In addition, our ability to control pH is important as pH affects these processes. ETI and the Adventus Group are supporting research at the University of Waterloo to help address some of the root problems of mercury contamination that are emanating from China. ETI is offering financial support to assist in a proposed project entitled 'Water well remediation of arsenic contaminated groundwater' with partners at the Chinese University of Geosciences. The arsenic problem is also widespread in China, and we see hope to include both zero valent iron and EHC-M as possible in-well treatment material candidates as part of the remediation solution.

Adventus Mercury Removal Solutions and Products
EHC-M is specially formulated for in situ immobilization of soluble metals via enhanced precipitation and adsorption reactions. The controlled-release feature of this patented product's carbon component provides for extended longevity, and greatly assists in maintaining very low redox conditions through simultaneous microbial consumption of the carbon and electron acceptors.

EHC-M is part of The Adventus Group's EHC brand umbrella, a family of latest generation bioremediation products used for the in situ treatment of groundwater and saturated soil impacted by heavy metals and persistent organic compounds such as chlorinated solvents, pesticides and energetics. The technology is a modification of their DARAMEND® technology, which has been successfully used since 1992 to treat more than 800,000 tons of similarly contaminated soil, sediment and solid wastes.
