US environmental regulators add three new sites to the national cleanup list

The US environmental regulators just added three new locations to the list of the country's most polluted sites. This means these sites will now get federal funding and attention for cleanup efforts.

The Superfund program is how the US government cleans up the worst toxic waste sites. Adding a site to this list means it gets priority for federal money and resources. This is a slow process, but it is the first step toward making these places safe again for people and the environment.
