Onondaga Lake dredging and cleanup restarts Thursday

Dredging to remove pollutants from Onondaga Lake is expected to resume three weeks after complaints of foul odors shut down the project.

The Syracuse Post-Standard reports the work is set to begin again Thursday after contractor Honeywell International added filters and equipment covers it expects will eliminate or reduce the problem at a treatment site in the Syracuse suburb of Camillus.

A mix of water and sediment is piped four miles from the lake to Camillus, where neighbors reported chemical odors after the cleanup began in July. Honeywell acknowledged they were a nuisance, but said they weren't a health threat.

Decades of waste dumping by industries surrounding the lake poured mercury and other metals along with solvents and PCBs into the water.
