Newtown Creek is a 3.5 mile river which empties into the East River in New York, United States. The river runs the boundary between the Queens and Brooklyn Burroughs. A thriving sight of industry, this river has been the location of much pollution for over a century. Battered by oil spills and oil seepage, raw sewage, trash carried by rain water, cement, animal fat, and a 15 meter sludge on the bottom of the riverbed, Newtown Creek is one of the most polluted waterways in the United States. In this article, data for nitrate, phosphate, lead, copper, dissolved iron, and chromate were collected over 6 months. Levels of lead were 10 times higher than the drinking water limit, and then diminished greatly over the 6 months.
