NPL (National Priorities List) sites

The National Priorities List (NPL) is a publicly available list of the most contaminated sites in the U.S. identified by the Environmental Protection Agency (EPA) for long-term cleanup. These sites typically have dangerous amounts of hazardous waste that pose health or environmental risks, such as polluted land, water, or air. Being on the NPL helps prioritize resources and efforts to remove or contain the pollutants, ultimately protecting communities and ecosystems from lasting harm.
