What Makes it so Effective?
- High persistence in the subsurface to overcome back diffusion issues at highly heterogeneous sites
- Neat, pre-blended colloidal ZVI suspension that eliminates clumping and other ZVI blending issues in the field
- Simple mixing and dilution without the need for further suspension chemistry
- Easily integrated as a combined remedy with other remediation chemistries and including anaerobic bioremediation or activated carbon sequestration
How Does It Work?
CleanER iZVI is a precisely blended liquid-suspension concentrate that is injected, via DPT or injection wells, to address chlorinated volatile organic compounds (CVOCs) and heavy metal contaminants, such as hexavalent chromium, arsenic, and selenium.
The unique formulation promotes broad dispersion in the subsurface at low and below fracture injection pressures, which optimizes distribution and contact. Through the process known as reductive dechlorination for solvents and chemical reduction for metals, the contaminants are degraded upon contact with the ZVI, and the byproducts are broken down into ethene and less hazardous forms of the target metals.
