Discover a single treatment approach.

CRP (Controlled Release Polymer) delivers a sustained dose of oxidants, mitigating rebound with controlled release groundwater amendments.

ISCO

Multiple Treatments

Rebounding is a common issue during in situ remediation. This returning of elevated contaminant levels following a treatment is currently addressed through repeat treatments injections - driving up cost, delaying time to completion, and prolonging exposure.

RemRx CRP ICSO

A Single Treatment

RemRxTM CRP is a controlled release technology for ISCO. 

It provides a sustained delivery of oxidants into the subsurface continually degrading contaminants and mitigating rebound.

A Sustained Delivery

RemRxTM CRP sustains oxidant delivery with a single application and continually treats dissolved phase contaminants.

Case Summary: VOCs at a Former Gas Station

Overview

This site, located in Eastern North Carolina, had impacted soil and groundwater from leaking underground storage tanks (USTs) and pump supply lines.

Site Specific

A site specific remedial design and prescriptive dosage was formulated consisting of a blended 3:4 ratio of both fast release and slow release CRP.

Remedial Approach

An excavation perimeter was defined based on estimating area of impacted soil below a former pump island. Amendments were placed adjacent to the surface aquifer.

Eliminating the Rebound

Not all contaminants are ​free to react with dissolved ​​remediation products.

RemRxTM CRP delivers a sustained oxidant with a single application
​that continually treats dissolved phase contaminants.

What Causes Rebounding?

The mass of contaminant at a site takes many forms. It can be dissolved in groundwater, sorbed onto solids in the aquifer sediment, and/or standalone as a separate non-aqueous base.
Contaminant concentrations are dictated by many dynamic processes, including the aquifer’s geophysical and geochemical environment, solubility, groundwater pH, and groundwater oxidation-reduction potential. 

Oxidant and contaminant reaction kinetics are faster in the dissolved phase, making sorbed contaminants much more resistant to treatment. Rebounding occurs when these contaminants desorb and partition back into the aqueous phase.
