Trap & Treat®

Contaminant back diffusion from soils and bedrock may be one of the most important factors to consider during in-situ remediation. The ITRC states that “At many sites back-diffusion can sustain plumes long after source removal and result in very long time frames for complete restoration of groundwater plumes”

For years the environmental industry has been demanding an injected material that is effective over the long term to address back-diffusing contaminants.

The Trap & Treat® Amendment

Trap & Treat® activated carbon amendments have entered the Canadian in-situ remediation market and have been demonstrated to provide full remediation with a single application at most sites.

The two main injection amendments are:

  • For chlorinated solvents treatment: Trap & Treat® BOS 100®
  • For petroleum hydrocarbon treatment: Trap & Treat® BOS 200®

Trap & Treat® BOS 100®

BOS 100® consists of activated carbon impregnated with metallic iron. First, contaminants are “trapped” by the carbon, and then “treated” by reaction with the metallic iron.

BOS 100® was developed for rapid and long-term remediation of chlorinated solvents with typically only a single application.  BOS 100® is applicable for plume or PRB treatment of chlorinated solvents in various geologic settings including overburden materials as well as fractured bedrock environments.

Benefits of BOS 100® Remediation

  • One application is typically required because of the robust delivery approach and the ongoing capacity of activated carbon to address desorption rebound
  • Immediate mass reduction and plume control since carbon traps contaminants in place while iron degrades them over time
  • Less health risks since no release of toxic daughter break-down products
  • Treatment to parts per billion (ppb) concentrations can be achieved 

Trap & Treat® BOS 200®

BOS 200® consists of activated carbon, terminal electron acceptors (TEA), nutrients and a facultative blend of aerobic and anaerobic bacteria. First, contaminants are “trapped” by the carbon, and then “treated” by biological degradation.

BOS 200® was developed for rapid and long-term remediation of petroleum hydrocarbons with typically only a single application being required. BOS 200® is applicable for plume or PRB treatment of LNAPL and dissolved phase petroleum hydrocarbons in various geologic settings including overburden materials as well as fractured bedrock environments.

Benefits of BOS 200® Remediation

  • One application is typically required because of the robust delivery approach and the ongoing capacity of GAC to address desorption rebound
  • Works in variety of soil conditions because the biological degradation is first aerobic (oxidation) and then anaerobic (nitrate and sulphate reduction)
  • Non-toxic and it has no adverse impacts on soil properties or groundwater quality
  • Treatment to parts per billion (ppb) concentrations can be achieved

Remediation Products Inc.

Trap & Treat® products were developed by Remediation Products Inc. (RPI). Here’s the story of how the products were developed:

RPI Group has developed a network of approved installers around the globe. In 2015, Vertex became the first licensed applicator of Trap & Treat® products in Canada.
