Parents are on edge in Newburgh after learning the water at local schools was contaminated with lead.

Meadow Hill Elementary School is reportedly one of three schools hit the worst by the lead contamination first found in 2014.

The Newburgh Union Free School District announced this week that volunteer testing by the Environmental Protection Agency discovered 150 sinks and water fountains throughout the district had dangerously high levels of lead.

Administrators say that immediate steps were taken to fix the problem, including repeated testing through January 2016. They add that the issue is no longer present.

Lead is known to cause a number of developmental and health problems in children exposed, and many concerned parents are now wondering why they weren't notified sooner. At this point, it is unclear what the level of lead was.

City Mayor Judy Kennedy says she does not have any information about the problem and only found out about it this week.

Calls placed by News 12 to district administrators for comment were not returned.

On Monday, Newburgh officials announced that the city's water supply has elevated levels of PFOS, a chemical found in cleaning supplies. They say that issue has been temporarily fixed.
