AquaBlok+^™: Composite Particle System. This composite aggregate technology resembles small stones and is comprised of a central core (often stone aggregate), clay or clay sized materials, and polymers. The composition, size and gradation of the particles can be custom designed for many different uses as a vector delivery system. Numerous environmental engineers and scientists are using AquaBlok in innovative applications - particularly for sediment, ponds, lagoons, etc. impacted by chlorinated hydrocarbons, pesticides, PCBs and heavy metals.

DARAMEND^®: An EPA / SITE approved biological treatment technology for soil, sediment, and solid wastes contaminated with recalcitrant organic compounds. The technology has been successfully applied to more than 7,000,000 tons of soil, sediment, and other wastes contaminated with polycyclic aromatic hydrocarbons (PAHs), PCP, phthalates, chlorinated herbicides and pesticides, organic explosive compounds and wood preservatives at a variety of industrial and military sites in the United States, Canada, Australia and Europe.

EHC^®: Enhanced aerobic and anaerobic bioremediation. A family of remediation 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. EHC is a controlled-release, integrated carbon and zero valent iron (ZVI) source that yields redox potential (Eh) in the -500 to -650 mV range. This Eh is significantly lower than that achieved when using either organic materials (lactate, molasses, and sugars) or reduced metal alone. Eh potentials in this range facilitate the timely and effective removal of normally recalcitrant chlorinated organics (e.g., CT, PCE) and other persistent compounds (e.g., perchlorate) without the formation of potentially problematic intermediates, such as DCE/VC from the anaerobic degradation of PCE/TCE or CF/DCM from the anaerobic degradation of CT. Superior to competitive Hydrogen Release Compounds.

EHC-A^®: This patented technology is a cold-water soluble formulation of EHC that is specially designed for injection via existing wells or hydraulic injection networks for the treatment of a wide range of groundwater contaminants. It is composed of primarily controlled-release food-grade organic carbon and dissolved iron. Application of EHC-A will greatly enhance the in situ reduction of persistent compounds such as chlorinated solvents, chlorinated pesticides, and energetics through a combination of biostimulation and chemical reduction resulting in very low redox levels.

EHC-F^®: This patented technology is composed of controlled-release food-grade organic carbon plus fine-grained particles of actual ZVI. The organic components of EHC-A/EHC-F are hydrophilic and soluble in cold water. As described above, the addition of soluble carbon to the subsurface will support the growth of indigenous heterotrophic bacteria in the groundwater environment. As they feed on the soluble carbon, the bacteria consume dissolved oxygen, thereby reducing the redox potential in groundwater. In addition, as the bacteria ferment organic carbon, they release a variety of volatile fatty acids (VFAs, for example acetic, propionic, butyric), which diffuse from the site of fermentation into the groundwater plume and serve as electron donors for other bacteria, including dehalogenators and halorespiring species.

EHC-M^®: Specially formulated for in situ immobilization of soluble metals via enhanced precipitation and adsorption. The controlled-release feature of the carbon provides for extended longevity and greatly assists in maintaining very low redox conditions through simultaneous microbial consumption of the carbon and electron acceptors. Arsenic, for example, is precipitated through the production of iron arsenic sulphide minerals that are practically insoluble in groundwater. Superior to competitive Metals Remediation Compounds.

EHC-O^®: Enhanced aerobic bioremediation. Controlled release oxygen compound that contains an oxygen releasing component that provides a long-term source of dissolved oxygen. Native microorganisms utilize the dissolved oxygen as an electron acceptor, and the targeted contaminant serves as the electron donor resulting in its destruction. The organic carbon component of EHC provides trace micronutrients required for healthy growth and proliferation of the indigenous, naturally occurring microbial population. Superior to competitive Oxygen Release Compounds. Available as O-Sox for well applications. Sleeves or reusable stainless steel canisters, in varying sizes and longevities.

mGCW^™: Microbiologically enhanced vertical groundwater circulation well (mGCW) technology significantly modifies conventional GCW systems to effect the removal of inorganic constituents (e.g., heavy metals and nitrate) and/or accelerate the biodegradation of persistent organic compounds under aerobic (e.g., high-molecular-weight PAHs) or anaerobic (e.g., organic explosives, perchlorate, chlorinated hydrocarbons) conditions. The mGCW systems are specifically designed and uniquely configured to provide accelerated aerobic, enhanced anaerobic or sequential anaerobic/aerobic reactions. These reactions facilitate terminal destruction of persistent organics, appropriately coupled with the removal of inorganic constituents where needed. mGCW technology can simultaneously provide in situ treatment of soil (vadose zone) and the saturated zone without removing groundwater. World renowned German technology.

TERRAMEND^®: An inorganic soil amendment that provides an optimized balance of major, minor, and micronutrients designed to cost-effectively enhance bioremediation of soils, sediments, and solid wastes impacted with petroleum hydrocarbons, including gasoline, diesel fuel, jet fuel, heating oil, bunker-C, and a wide variety of other petroleum-based compounds. Also used as an organic fertilizer for farming, golf courses, and grass farms.
