An innovative remedy at the Henry's Knob Superfund Alternative site is protecting public health and the environment while also serving as vital native habitat for pollinators and other species. The remedy was designed by Amec Foster Wheeler Environment and Infrastructure (Amec Foster Wheeler) for a Confidential Client who was one of the site’s responsible parties. A collaborative working relationship between the responsible party, Amec Foster Wheeler, EPA, and the South Carolina Department of Health and Environmental Control (SCDHEC) made revitalization of the former mine site possible.
