VALHALLA - Emergency responders contained a chlorine leak early this morning at the Kensico Dam water treatment plant in Valhalla, though the environmental impact remains unclear.

The Department of Environmental Protection says the spill in shaft 18 of the facility on Westlake Drive was caused by a leak to a pipe containing water mixed with chlorine. A spokesperson from the agency told News 12 that the water supply was not affected.

Firefighters and hazardous materials crews say it took hours to contain the leak, which started last night at around 7:30 p.m.

No one was hurt during the incident. Officials say they expect the leak to be fixed by the end of the week.

The plant treats water that ends up in Westchester County. That water feeds to New York City and parts of Westchester.

Westchester towns are shouldering the task of disinfecting water that ends up in area communities.

An investigation into the incident is ongoing.
