Lower North Potato Creek Watershed Project (Polk County) - Glenn Springs Holdings Inc., the Tennessee Department of Environment and Conservation and the United States Environmental Protection Agency has been remediating the environmentally degraded Lower North Potato Creek Watershed for the past 14 years. Dating back to the 1850s, the watershed, part of the Copper Basin in Polk County, was a site of extensive copper mining and processing. To improve the water quality and biological integrity and diversity, Glenn Springs Holdings Inc. has installed and is maintaining fences to restrict access to designated hazardous areas, removed and isolated waste materials, constructed passive and active water treatment systems, captured poor quality water for treatment, diverted water of good quality, enhanced vegetation and wildlife habitat and restored stream segments and wetlands. In 2014, modifications were made to the North Potato Creek Wastewater Treatment Plant allowing contaminated water to get treated for metal removal before going to the Ocoee River.
Eureka Roast Yard: Acid-producing materials were removed and the area was capped and vegetated.
Burra Creek: A tributary of North Potato Creek was reconstructed by removing contaminated materials, replacing with healthy soils and constructing natural flow control and habitat enhancements.
