Over the years, we have successfully treated thousands of sites impacted by hazardous contaminants around the globe. To search our case studies, please use the filters provided at the right or enter a search term such as type of site (e.g. dry cleaner) or location (e.g. Florida).
EHC was injected into a series of permeable reactive barriers (PRBs) across the plume with the goal to treat the entire plume area over time. After only 6 months following the installation of the EHC PRBs, CT concentrations were reduced from a maximum of 260 ppb to 0.8 ppb (99.7% removal), with all monitoring wells meeting the groundwater clean up criteria for all chlorinated volatile organic compounds (CVOCs).EHC® ISCR Reagent Chlorinated Solvents
The groundwater at a former unregulated solid waste management unit was impacted by various chlorinated volatile organic compounds (CVOCs), mainly chlorinated ethenes. In February 2006, EHC® Reagent was injected into the gravel trenches to convert them into permeable reactive barriers (PRBs).EHC® ISCR Reagent Chlorinated Solvents
EHC® in situ integrated biological and chemical reduction (ISCR) technology was used to treat chlorinated aliphatic hydrocarbons (CAHs) safely, rapidly, and effectively at a manufacturing facility.EHC® ISCR Reagent Chlorinated Solvents
Following a truck accident on one of the main motorways in northern Italy, about 3,000 L of 1,2-dichloropropane was released into the ground, causing an immediate contamination of the soil and groundwater. 55,000 kg of EHC® Reagent was injected into a triangular grid of 42 injection points from one to six meters bgs.EHC® ISCR Reagent Chlorinated Solvents
The first full-scale application of EHC® Reagent into a flow-through reactive zone was installed in 2005.EHC® ISCR Reagent Chlorinated Solvents
