Groundwater Remediation with PlumeStop in Belgium

Regenesis and ABO have designed an appropriate and effective solution to remediate the contamination on site, and stop its migration over the side boundary. A PlumeStop barrier will be installed down gradient of the source zone. Which will allow ground water to flow freely through it, whilst rapidly absorbing and bio-degrading any contamination that migrates into the treatment area.

PlumeStop is an innovative remediation technology, which can achieve very low ground water targets in a short period. And then maintains this treatment for years after a single injection. Once injected, PlumeStop coats the subsurface with a one to two micro layer of activated carbon. This then absorbs the chlorinated solvents and provides a perfect surface on which to grow reductive de-chlorinating bacteria, which then degrade the contamination. This biological degradation frees absorption sites from further contaminant capture. This means that the barrier is self-regenerating and allows it to remain active for years.

Before the full-scale installation we are performing a pilot test to check field conditions. Chris Martin, technical manager for Europe explains.

Chris: Over there, there is a mixing tent where we prepare the PlumeStop. The PlumeStop is then pumped through this line to the drilling rank where we inject the PlumeStop in the sub-surface.

Narrator: The pilot application is being completed in an accessible area of the site, a narrow private driveway. The application is completed quickly with the driveway left neat and tidy. No further surface equipment is now required at the site while active remediation occurs in the groundwater below.

Initial results have shown a more than 99% reduction in contaminant levels in less than two months of application. Full-scale remediation is being planned for later this year.
