A contractor struck an underground spring, causing discolored water to leak into the Nissequogue River off of Paul T. Given Park, Smithtown town officials said.

The New York State Department of Environmental Conservation Spill Response Unit was on the scene yesterday around 9:40 a.m.

A town spokesperson said a worker was conducting state-mandated geotechnical boring tests, which are required by the town before it can obtain permits from the state to start repair work at the park.

The area, including the bridge, was heavily damaged during the massive storm that flooded parts of Long Island last August.

"While the strike to the spring was an unfortunate incident, the Town is working closely with the DEC to ensure the situation is addressed safely, effectively and without delay," a town spokesperson told News 12 in a statement.

The well was capped, but water is being released into manmade sediment treatment ponds before being discharged into the river, according to the state.

Town officials said they are coordinating all necessary remediation measures to protect the water and keep the bridge restoration project on track.

"We remain committed to completing the repairs at Paul T. Given Park as quickly as possible so that this important community space can be fully reopened for public use," a town spokesperson added in a statement to News 12.

The state Department of Environmental Conservation is actively investigating the incident.
