GEOFORM® Biochemical Reagents are engineered to deliver the building blocks needed to promote in situ biogeochemical reactions. GEOFORM® provides a source of sulfate, ferrous iron, electron donors, pH buffer, and nutrients to promote mechanisms for dehalogenation via enhanced anaerobic bioremediation, abiotic degradation, and the formation of reactive minerals. The component ratios have been optimized to maximize the formation of reactive iron sulfide minerals that provide an expanded surface area for abiotic degradation pathways. In addition, the amount of electron donor can be adjusted based on site specific geochemistry. GEOFORM® can be used for the treatment of groundwater and saturated soil impacted by persistent halogenated compounds and will also immobilize many heavy metals. GEOFORM® is available in two formulations – a fully soluble formulation for ease of injection and a solid formulation for extended release.
GEOFORM® Extended Release is formulated with a long-lasting source of hydrogen donor and zero valent iron (ZVI) for continued rejuvenation of iron sulfide minerals. It is ideal for Permeable Reactive Barrier (PRB) and source area treatment and has a longevity of 5-10 years. GEOFORM® Extended Release is applied via direct push, hydraulic, or pneumatic fracturing or soil mixing.
