The Gowanus Canal in Brooklyn is notoriously toxic. Since 1869, the mile-long waterway has been a dumping ground for garbage, industrial waste, guns and body parts—its waters once too dirty to search. Today you can still stand on a bridge over the canal and see underwear floating on the water. The odor, once almost unbearable, has softened into an occasional summerstink, thanks to a flushing tunnel installed 10 years ago.A growing number of artists and young people have moved into the industrial lofts and row houses nearby. Some of the most oblivious have been spotted on the canal in canoes, their paddles stirring 140 years worth of detritus (small pieces of rubbish) from leather factories, chemical plants and more. Now, these Gowanus pioneers want somebody to finally detoxify their hazardous neighborhood. They imagine it as Brooklyn"s little Venice, although a bit cleaner. The Environmental Protection Agency (EPA) is considering naming the Gowanus an official Superfund site. That would bring in a slow but steady federal cleanup with money and the legal influence to force polluters to help pay. The present Mayor of the New York City also wants a cleaner Gowanus, but he wants to do it his way. At a community board meeting Tuesday night, about 200 people listened as the mayor"s experts argued against a Superfund listing. It was a hard crowd to move. Many wore a button that said it all: "Gowanus Canal: Superfund Me." The mayor and his team are particularly worried about how a Superfund site would affect the real estate market, especially a few possibilities for larger developments in the area. Instead of being "stigmatized" by the Superfund label, as they put it, they favor the "Superfund Alternative" plan. Although there are few details at this point, that effort would be run by the city and overseen by the EPA Every year, the city would rush to collect funds from the Corps of Engineers and other agencies to help clean up the area to the EPA"s satisfaction. The city could only plead with polluters to help pay. With so many pollutants and so many polluters, this looks like a job for Superfund. Brooklyn can handle the label. Residents already enjoy boasting about their survival or joking about living near the canal"s dark humors. Why else have a popular bar called the Gowanus Yacht Club They just want the cleanup done and done right. In the opening paragraph, the author introduces his topic by_____.
