Improved Activated Carbon-Based Products in Canada!

Improved Activated Carbon-Based Products in Canada!

What was the biggest game changer in the in-situ Canadian environmental market in recent years? In our opinion it was the entry of the first activated carbon-based, injectable remedial amendments in 2015. Well, the remediation game has just been stepped up: the next generation of these activated carbon-based products are now available in Canada!



The original Trap & Treat® BOS 100® and BOS 200® are powerful remedial amendments designed to quickly and permanently destroy chlorinated solvents and petroleum hydrocarbons in groundwater. We called these activated carbon-based products “gamechangers” based on the speed at which they can remediate groundwater. The charts below illustrate how quickly groundwater concentrations can drop following remedial injection activities. This is crucial at sites where post-remediation groundwater quality monitoring needs to start quickly. Instead of waiting for months, in most cases groundwater monitoring can start after only a few weeks!

But it wasn’t only a short-term gain; the groundwater concentrations were proven to stay low over the long term based on the treatment mechanisms that are coupled with carbon adsorption, as illustrated in the next chart that shows one year of post-remediation groundwater monitoring results with that all-imported “four quarters clean” set of results.

However, a limitation of this first generation of activated carbon-based remedial amendments was the challenge of overcoming high soil concentrations or non-aqueous phased liquids (LNAPL and DNAPL). After all, activated carbon can only adsorb so much mass. That is what this next generation of activated carbon-based products has been designed to overcome.

Trap & Treat® CAT 100 and BOS 200+® technologies are the like the original amendments on steroids. They represent catalyzed versions of BOS 100® and BOS 200® that allow rapid remediation at sites with more recalcitrant compounds, high soil masses of contaminants, and even sites with LNAPL and DNAPL present. CAT 100 combines the original powerful remediation mechanisms of carbon adsorption and chemical reduction with enhanced anaerobic biodegradation. BOS 200+® combines the original carbon adsorption and anaerobic biodegradation with an enhanced form of catalyzed biotechnology. As a result, these next generation products can overcome the mass limitations of activated carbon to allow rapid remediation of even the most highly impacted petroleum hydrocarbon and chlorinated solvent sites. And, as with the original products, these are also applicable for entire plume or PRB treatment of organic contaminants in various geologic settings including overburden soils, groundwater and even fractured bedrock.

Lastly, as an added benefit of using Trap & Treat® products, cradle-to-grave, pro bono laboratory analytical services are offered in Remediation Products Inc.’s Quality Assurance Laboratory to provide detailed quantitative data to support the upfront design as well as post-application performance monitoring purposes. Any remediation contractor or product supplier will tell you that it is important to understand the contaminant mass distribution in the subsurface so that a remediation plan can be prepared to apply the right amount of remedial amendment in the right locations in order to contact the contaminant mass and achieve remedial success. This is precisely why this service is offered free of charge: to ensure that the right remedial design is developed for your site.

The remediation game has just been changed. Are you ready to play?
