Groundwater Treatment Begins at Asheville, N.C., Superfund Site

Electrical Resistance Heating (ERH) will treat contaminants at the former electronics manufacturing site

Groundwater treatment begins at EPA Superfund Site

Work is underway at the CTS Inc. Superfund Site of Asheville, N.C., to install the treatment system that will clean up contaminants in the groundwater and soil beneath the former CTS plant.

Electrical Resistance Heating (ERH) will be used to treat contaminants beneath the former CTS plant. These contaminants include trichloroethene (TCE) and light nonaqueous phase liquid (LNAPL) from weathered fuel oil. CTS has contracted with TRS Group, Inc. to install and operate the treatment system, with oversight from U.S. Environmental Protection Agency (EPA).

ERH is a technology that heats the ground to extract and treat hazardous substances. Electricity runs through electrodes, heating the soil and groundwater to vaporize the contaminants. The vapors are captured and removed through extraction wells. Contaminated vapor is then treated above ground before being discharged to the air.

The CTS of Asheville, Inc. Superfund Site was the location of an electronics manufacturing and electroplating facility that operated from 1952 until 1983. Historical use of solvents in the manufacturing of electronic components at the CTS Site contaminated the soil and groundwater with TCE and other volatile organic compounds. TCE has been linked to illnesses ranging from effects on the central nervous system, liver, kidneys and immune and endocrine systems to certain types of cancer.
