Gareth Leonard, Managing Director of REGENESIS Europe, will be speaking at the Brownfield Briefing on the 14th September 2017 at 14.55 pm.

A decade of large-scale enhanced reductive dechlorination; examining the evolution in the usage of a high-volume controlled-release electron donor substrate.

Using case studies from technology launch up to ongoing projects, this presentation will discuss the development in the understanding, design and application of a slow release carbon substrate used to provide the enhanced reductive dechlorination of halogenated compounds.

Created to treat large-scale plumes synonymous with problematic chlorinated solvent contamination, the technology was created to transport widely through the subsurface post-injection, whilst avoiding wash-out and still providing an effective and sustained treatment rate.

The presentation will cover the lessons-learned through application into a wide range of geological and geochemical settings across Europe and America, targeting a number of contaminants, with concentrations ranging from DNAPL to low dissolved phase. It will also discuss the merits of integration of enhanced reductive dechlorination with physical and chemical technologies in order to optimise treatment onsite.
