mZVI Suspension for  In Situ Chemical Reduction (ISCR)

ISCR In Situ Chemical Reduction

In Situ Chemical Reduction (ISCR) is an innovative environmental remediation technique used for soil and/or groundwater remediation to reduce the concentrations of targeted environmental contaminants to acceptable levels.

Biodegradation Waterloo Emitters

The Waterloo Emitter is a simple, low cost device designed for the bioremediation of contaminated groundwater. Sized to fit 2", 4" and 6" wells and boreholes, can be installed in stacks vertically or horizontally to ensure full coverage of the contaminant plume. The controlled release of oxygen and various other amendments encourage and sustain the growth of microorganisms required for bioremediation.

ERD Electron Donors

Enhanced reductive dechlorination (ERD) requires adding sufficient organic substrate (electron donor, such as EDS-ER™, and nutrients, such as Nutrimens®) to satisfy electron acceptor demand from both inorganic and organic compounds (i.e. chlorinated solvents) in the treatment zone.

Zero Valent Iron (ZVI)

Looking for a ZVI solution? Tersus offers multiple grades of highly reactive ZVI that can be specially selected to meet the varying requirements of contaminated sites.


  • Micro (< 10 microns)
  • Fine (average 45 microns, or 325 mesh)
  • Medium (average 100 microns, or 150 mesh)

Soil Mixing

  • Coarse (100 to 250 microns)

Permeable Reactive Barriers (PRBs)

  • Granular (>250 microns)
catalyzed hydrogen peroxide (CHP)

ISCO Catalyzed TersOx™ Accelerate

Catalyzed TersOx™ Accelerate, a modified Fenton’s reagent, is formulated to generate hydroxyl free radicals that act as the active oxidizing agent.  This powerful and non-selective reaction has the ability to oxidize a wide variety of organic contaminants into non-regulated compounds, yet it is extremely stable to be blended as one product for subsurface injection, aboveground for safety, for long-lasting effects below ground, and to allow contact where needed.
