Once a tidal creek meandering through marshlands rich in herbs, grasses, fish, waterfowl, and oysters, Newtown Creek today is a toxic cesspool that brings up raw sewage every time it rains. A tributary of New York's East River that forms part of the border between Brooklyn and Queens, Newtown Creek has long been at the heart of the city's "industrial backyard," serving as home to numerous industries, storage/warehouse facilities, waste transfer stations, and power plants, and as the dumping ground for unwanted byproducts and toxic waste. Site of a 17-million-gallon underground oil spill that still contaminates the area, Newtown Creek is currently under consideration by the Environmental Protection Agency for designation as a Superfund site, but the creek, whose waterfront is for the most part inaccessible to the public, is still largely unknown to residents and visitors of New York alike.
