A DECADE OF LARGE-SCALE ENHANCED REDUCTIVE DECHLORINATION: THE EVOLUTION IN THE USAGE OF A HIGH-VOLUME CONTROLLED-RELEASE ELECTRON DONOR SUBSTRATE AT URBAN BROWNFIELD SITES
Leonard, G. | Intersol 2018: International Conference-Exhibition on Soils, Sediments and Water, March 27-29, 20 slides, 2018
Lessons learned are presented from a review of results from 24 target treatment zones where a slow-release carbon substrate was used to provide enhanced reductive dechlorination of halogenated compounds. Created to treat large-scale plumes synonymous with problematic chlorinated solvent contamination, the technology was developed to transport widely through the subsurface post-injection while avoiding wash-out and still providing an effective and sustained treatment rate. The substrate has been applied in a wide range of geological and geochemical settings across Europe and America, targeting a variety of contaminants, with concentrations ranging from DNAPL to low dissolved phase. https://www.intersol.fr/download/28032018/download.php?f=Intersol_2018_5-Gareth_Leonard_Regenesis.pdf
