Discover a single treatment approach.

CRP (Controlled Release) delivers a sustaining dose of oxidants.

Typical 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

RemRx® 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

RemRx® 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 emplaced interfacing the surficial aquifer.

Eliminating the Rebound

Over time, contaminants change physical states.

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

What Causes Rebounding?

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 contaminant desorb and partition back into the aqueous phase.
