The settlement was filed Thursday, and applies to Water District No. 1 – which serves Mount Vernon, Scarsdale, White Plains, and Yonkers.
The U.S. Environmental Protection Agency had filed the federal court case against Westchester County.
Westchester officials have a little less than a month to pay the required $1,108,771 fine, according to court records.
The county must also complete construction of two ultraviolet water treatment systems in White Plains – one at the Central Avenue pumping station and the other at the Orchard Street pumping station, court records show.
It should cost Westchester no more than $691,000 to comply with those provisions of the settlement, according to court records.
