For almost 50 years, facility operations at a Collierville, Tennessee, manufacturing site contaminated groundwater, surface water and soil. With the addition of the site to the National Priorities List (NPL) in 2005, the U.S. Environmental Protection Agency (EPA) needed a trusted partner to clean up the site in order to protect people and the environment from contamination. As one of the three original Superfund contractors since the Superfund Act’s inception in 1982, Black & Veatch took the lead in helping the EPA meet its goals.
