Nassau County has been ordered to pay up for alleged environmental violations.

The Environmental Protection Agency had filed suit against the county for allegedly not maintaining dozens of underground storage tanks at its facilities.

On Wednesday, the U.S. Attorney's Office issued a "consent judgement" requiring the county to pay more than $427,000 dollars in fines and install equipment to detect leaks in the tanks.

"These tanks contain gasoline, fuel oil, both of which we don't want mixing with our underground drinking supply in our aquifer," says Adrienne Esposito, of Citizens Campaign for the Environment. "So the maintenance of these tanks, and the monitoring of them, is critical really, to protecting our ground water supply."

The alleged violations stem from 2008 to 2017 at 48 facilities run by the Nassau County Department of Public Works.
