Provect-ERD is an emulsified liquid electron donor used to create enhanced reductive dechlorination (ERD) conditions in groundwater for anaerobic bioremediation of chlorinated solvents (e.g., PCE, TCE, DCE, and VC). The technology is developed on a site-specific basis with a range typically containing 60 - 70% fermentable carbon (FC), several short and long-term carbon sources, and the addition of Provectus antimethanogenic reagents (AMRs). Furthermore, our Provect-ERD with antimethanogenic reagents (Provect-ERD CH4) can be formulated with different types of methane inhibitors at different concentrations, typically between 2 and 8% of FC. The primary benefits of Provectus ERD-CH4 over other marketed reductive technologies are:

• Completely soluble in water hence no need for extensive and time-consuming “water chase”.
• No need to emulsify the product with specialized tooling and equipment.
• No laborious material transfers and dilutions.
• Lower injection pressures.
• ERD-CH4 is formulated for each site-specific application.
• Avoids cost and need for contingency planning to manage excessive methane production (SVE/AS off gas treatment).
