OAK RIDGE, Tenn. (AP) - Evidence of radioactive pollution lingers at the Oak Ridge sewage treatment facility, and it’s not clear when the problem will be resolved.

The Knoxville News Sentinel reports (https://bit.ly/1QUL8zC) the radioactive pollution was discovered in early 2014, and was blamed on technetium-99 that had migrated from a demolition project at the federal government’s K-25 uranium-enrichment plant on the other side of the Clinch River. The radioactivity reportedly didn’t pose a health threat, but it prompted cleanup actions.

About 75,000 gallons of radioactive sludge have been removed from the facility. URS-CH2M Oak Ridge spokeswoman Anne Smith says it’s “premature” to estimate when the facility will be back to “normal operating parameters.”

Smith says URS-CH2M Oak Ridge will either remove contaminated piping before demolition begins or seal the equipment with foam to keep the contamination in place.
