Provect-IR® Antimethanogenic ISCR (In Situ Chemical Reduction) Reagent

Provect-IR® is a unique mixture of reagents combined into a single product that optimizes the in-situ reductive dechlorination of chemicals present in soil, sediment, and groundwater. It acts by promoting synergistic interactions between:

  • Natural antimethanogenic compounds
  • Hydrophilic, nutrient rich organic carbon sources
  • Zero-Valent Iron (ZVI)
  • Chemical oxygen scavengers
  • Vitamin and mineral sources

This distinctive, patented combination of natural and food-grade chemicals promotes ISCR conditions for fast and effective destruction of targeted constituents of interest such as chlorinated solvents, organochlorine pesticides, and other halogenated compounds. Notably, Provect-IR is the only ISCR reagent to simultaneously inhibit the production of methane during the requisite carbon fermentation processes. This promotes more efficient use of the hydrogen donor while avoiding negative issues associated with elevated methane (CH4) in groundwater, soil gas, and indoor air. Current regulations for methane in groundwater vary from ca. 10 to 28 mg CH4/L (Indiana Department of Environmental Management, 2014) with additional State regulations pending. Furthermore, remedial practitioners have subsequently been required to establish contingencies for conventional ERD/ISCR implementation in the event that methane exceeds specific groundwater thresholds. These contingencies often entail expensive and extensive systems for capturing and treating methane in soil gas/vapor captured via SVE systems.
