The United States Environmental Protection Agency (or EPA) has added seven new hazardous waste sites to Superfund’s National Priorities List (NPL).

These sites expose materials that can potentially harm people and the environment. Aside from these, the EPA has recommended another five new sites to the list.

Superfund is the government’s initiative tasked to probe and tidy up the country’s most complex and abandoned lethal waste sites in order to protect the health of the people as well as the environment.
