MCCRACKEN COUNTY, KY (KFVS) - A belowground heating system is helping to clean up the leading source of groundwater contamination at the Department of Energy’s Paducah Gaseous Diffusion Plant site.

The electrical resistance heating system features 52 borings, each with three 10-foot-long metal electrodes that heat soil to more than 194 degrees Fahrenheit to evaporate the degreaser trichloroethene that seeped into the ground over the years.

Vapor and water are then pumped to the surface and treated using carbon filtration, which is commonly used to adsorb volatile organic compounds, and air stripping, which uses airflow to remove substances from water through volatilization.
