It is the 1940s in Maywood, N.J. A new residential community has sprouted up, and the homeowners want to beautify their front lawns, so they go to a nearby property to gather some fresh topsoil. Little did they know that they’re helping to plant the seeds for one of the largest and most high-profile environmental cleanup projects in the nation.

The Environmental Protection Agency announced last week that it is adding Oklahoma’s Fansteel Metals/FMRI Superfund site to the National Priorities List. The list includes the nation’s most serious uncontrolled or abandoned releases of contamination and serves as the basis for prioritizing EPA Superfund cleanup funding and enforcement actions.

The Environmental Protection Agency has proposed adding the Fansteel Metals Superfund site in Muskogee, Okla., to the National Priorities List (NPL), the roster of the nation’s most contaminated sites that threaten human health or the environment. By adding this site to the NPL, the EPA said it can prioritize funding for cleanup and necessary enforcement action.
