Christopher Swain, an environmental activist, spent about an hour swimming in New York’s Gowanus Canal earlier this week on Earth Day. He said he made his swim as a “call for an accelerated cleanup of the Canal.” The Gowanus Canal is a 1.8-mile-long waterway connecting Upper New York Bay (the bay in between Brooklyn, Manhattan, New Jersey, and Staten Island) with the formerly industrial interior of Brooklyn. It is also one of North America’s most polluted waterways and has been a “Superfund” site since 2010. In 2013, the Environmental Protection Agency developed a cleanup plan which is expected to cost $506 million and should be completed by 2022. It is unclear how Mr. Swain’s swim will speed up the process.
