BROOKLYN, N.Y. -  The Prospect Park YMCA remains closed Friday because of a contaminated water supply

The Y says the water was contaminated with propylene glycol Monday when a vendor was working on the air conditioning system. 

According to the CDC, propylene glycol is generally considered non-toxic.

But the Y says if you drank water at the Y after 6 p.m. Monday and you feel unwell you should seek medical attention.

All previously planned program and camp activities have been moved, canceled, or rescheduled. 

Members of the Y at Prospect Park can visit any other branch in New York City during the closure.
