Mayor Michael Bloomberg on Monday touted his administration's efforts to clean up one of the city's most polluted waterways.
The Gowanus Canal has been polluted for decades.
The city says it has spent billions trying to clean it up, including a new pumping station which will help prevent sewage runoff and bring in clean water from a nearby source.
The mayor hopes to have the Gowanus safe for boaters by the end of the year, though swimming is a different story.
"It would not be a good idea to swim in it. There's hundreds of years of dumping stuff into the canal. It's in the ground, underneath it, it keeps leaching in. This was the industrial part of New York City. Its a big industrial city. They didn't have the foresight to realize what they were doing. It was just a different world," Bloomberg said.
A $500 million program by the Environmental Protection Agency to dredge the canal is also in the works, though officials say it's still a few years away.
