Onondaga Lake dredging suspended for the winter months

Dredging to remove contaminated muck from a central New York lake has shut down for the winter.

A Honeywell spokeswoman says the company has removed 233,000 cubic yards of sediment from Onondaga Lake since it began the $451 million project in July.

The work is expected to take four years. The company will dredge up 2 million cubic yards of sediment contaminated with mercury, benzene and other chemicals.

Onondaga Lake was once considered one of the most polluted bodies of water in the country. The cleanup project is the biggest lake dredging project for environmental remediation in the history of the state.
