Update for Week of June 18, 2018:
ERH Treatment System Begins Operation
The Electrical Resistance Heating (ERH) treatment system began operating on June 8, 2018. The system will operate through the fall to remove trichloroethene (TCE) in the ERH treatment area.
The treatment system will gradually raise the underground temperatures of soil and groundwater to vaporize TCE within the treatment area. It will take approximately 40 days to reach the target treatment temperature of 87° Celsius. Vaporized TCE will be destroyed by an on-site thermal treatment unit. During system operation, we are monitoring air emissions from the thermal treatment unit and the site perimeter. The air monitoring results will be available on EPA’s website at https://cumulis.epa.gov/supercpad/cursites/csitinfo.cfm?id=0402598.
CTS will continue to provide project updates on this website, including:
Please note that you may see occasional steam from the thermal treatment unit during system operation. This is normal water condensation caused by weather conditions, and not a release of TCE vapor. For additional information about the ERH treatment system start up, please see the EPA News Release: Treatment Begins at CTS of Asheville Superfund Site (https://www.epa.gov/superfund/superfund-task-force-accomplishments#asheville).
