A-SOX^™ -- easiest deep plume and routine deployment of Integrated Carbon, ZVI and Nutrients. Affordable and effective socks for stimulating anaerobic biodegradation in ground water wells.

AquaBlok+^™ -- composite-aggregate technology resembling small stones and comprised of a central core, 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^® -- advanced biological treatment technology for soil, sediment, and solid wastes contaminated with recalcitrant organic compounds.

EHC^® -- 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.

EHC-O^® -- a 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 this proprietary aerobic technology provides trace micronutrients required for healthy growth and proliferation of the indigenous, naturally occurring microbial population.

EHC-M^® -- specially formulated metal remediation compound 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.

HoleBlok+^™ -- innovative down-well sealant product provides all the benefits of traditional bentonite pellets, but also provides added protection from potential contamination by organics (i.e. TCE, etc.).

ISGS^™ -- In situ geochemical oxidation for the purposes of NAPL stabilization entails the use of a modified permanganate solution (KMnO4, or NaMnO4) that is flushed through an aquifer zone suspected to contain residual NAPL.

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., highmolecular-weight PAHs) or anaerobic (e.g., organic explosives, chlorinated hydrocarbons) conditions.

Modeling Services -- Remedial design and optimization, including: Optimal remedial design parameters; Time required for cleanup; Natural attenuation in untreated plumes; Contingency plans for attaining cleanup goals; Criteria for reduction or shutdown of active remediation; Reduction in monitoring program; and Remedial performance evaluations.

O-SOX^™ -- stimulation of aerobic biodegradation through controlled-release oxygen and nutrient delivery. For organic constituents amendable to aerobic biodegradation processes: Petroleum Hydrocarbons, light PAHs, BTEX. Significant cost savings realized through the use of EHC-O due to its higher oxygen release rate and lower price.

TERRAMEND^® -- inorganic soil amendments that provide 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.

ZVI PRB -- the world's leader in application of permeable reactive barrier (PRB) technology for in situ remediation of groundwater impacted by volatile organic compounds (VOCs). A typical PRB configuration consists of a zero-valent iron (ZVI) emplaced across the flow path of a VOC plume. As plume flows through the PRB under natural gradients, the VOCs are destroyed to non-toxic end products.
