EPA plans 5,000-foot underground barrier to contain Koppers Superfund site contamination

The U.S. Environmental Protection Agency is moving forward with the next phase of cleanup at the Cabot/Koppers Superfund site in Northwest Gainesville, anchored by a 65-foot-deep underground wall stretching roughly 5,000 feet to prevent contaminated groundwater from spreading. The roughly 140-acre former wood-treatment facility accumulated decades of hazardous materials including arsenic and creosote, and cleanup work is set to run from this month through mid-2027. The plan also includes removing contaminated soil and sediment, replacing a stormwater ditch with a new piping system, and continuing groundwater treatment, with current property owner Beazer East helping to fund the effort.
