Mitigate Rebounding

Versatile & Tunable
A Prescriptive Dosage
Complicated hydrogeological aspects in the subsurface mean that each contaminated site is unique.
We use a highly tunable polymer-based matrix that allows release of targeted oxidant doses under specific treatment times and conditions. Our tunable technology allows for a prescriptive remediation strategy that is not possible with traditional dissolved oxidant solutions. Currently available as permanganate and persulfate.
Deployment Versatility
The easy to handle, solid material can be placed directly into the contaminated zone, established in a permeable reactive barrier, or spread throughout an area following excavation as a “polishing” step. |

Eliminating the Rebound
Over time contaminants change physical states.
RemRx® CRP Sustains delivery
through dissolved and aqueous phases. |
Contaminant mass can be dissolved in groundwater, sorbed onto solids in the aquifer sediment and as a separate non-aqueous base. The contaminant concentrations are the result of the dynamic combination of the aquifers environment, solubility and the groundwaters pH. Oxidant and contaminant reaction kinetics are faster in the dissolved phase thus sorbed contaminants are not as efficiently treated. Rebounding occurs when contaminants desorb and partition back into the aqueous phase. |
