Redevelopment at the Site

The Saltville Waste Disposal Ponds Superfund site is located on the border of Smyth and Washington Counties along the North Fork of the Holston River in Virginia. The site covers 125 acres, and includes two large former waste disposal ponds and the former location of a chlorine manufacturing plant. Site investigations in the 1970s identified high mercury levels in site soil, groundwater and sediments of the North Fork of the Holston River as far as 80 miles downstream of the site. The two waste disposal ponds on site contained both mercury and alkaline waste material. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1983. The site’s potentially responsible party (PRP) conducted cleanup activities.  Initial cleanup included dredging mercury-contaminated sediments from the river, diverting clean surface water around the disposal ponds, and installing and operating a water treatment system.  In 2003, the PRP installed a RCRA cap over one disposal pond, a soil cover over another and   planted grasses, shrubs and trees over the cap and cover to support a wildlife habitat area.
