Concerns in Croton-on-Hudson this morning after officials say more than 50,000 gallons of sewage spilled into the Croton River.

The spill happened Wednesday, but Croton-on-Hudson village officials weren't alerted until a day later and that has some people upset.

The sewage spill started at the Crotonville pump station in Ossining that's run by the Westchester County Department of Environmental Facilities.

County officials say debris and dirt blocked a sewage line on Wednesday, causing 57,000 gallons of sewage to spill into the Croton River which discharges to the Hudson River.

Croton-on-Hudson is downstream of the spill and village officials say they weren't alerted until Thursday.

They also say river water in the vicinity of Mayo's Landing and the Echo Canoe Launch where people boat and swim were potentially impacted by the spill on Wednesday.

"I was swimming here and just found this out now, so that's kind of bizarre. Honestly they should let us know about it," says Daniel Sherry, of Croton-On-Hudson.

County officials say at this point, no impact on the Croton River is expected from the discharge.
