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® Soluble is formulated to deliver as a fully soluble dry powder in two parts: GEOFORM® Soluble Mix – a proprietary blend of sulfate and ferrous iron and ELS® Microemulsion or ELS® Concentrate - a 25% or concentrated organic carbon substrate. GEOFORM® Soluble remains fully in the solution during mixing and injection, is ideal for plume and hot-spot treatment, and has a longevity of 2-3 years. It is applied via injection wells, infiltration networks, or direct push.
Key facts:
• GEOFORM® Soluble Mix is a proprietary blend of sulfate and ferrous iron that when combined with ELS® organic carbon products generates reactive minerals in situ
• Remains fully in solution during mixing and injection
• Ideal for plume and hot-spot treatment
• Longevity of 2-3 years
• Application via injection wells, infiltration networks or direct push
• Composition: Soluble sulfate and ferrous iron mix added to an emulsified organic carbon substrate
