The Long Island Sound Study tracks the extent of hypoxia (low dissolved oxygen) in bottom waters of the Sound over the summer. Oxygen in the water is important, because fish and other animals need it to survive, just like animals on land. Excess nitrogen, an important nutrient for life, leads to oxygen removal from water, as explained in this infographic.

The Glen Cove Starch Works began when the Duryea Corn Starch Manufacturing Company relocated from Oswego NY to the south side of Glen Cove Creek in the 1850s. By the time of the Civil War, the plant was the world's largest producer of starch. In its heyday, the plant covered 30 acres and employed more than 700, many of them Irish immigrants who lived in company-owned housing and bought provisions at a company-owned store. The starch works used locally raised corn for its product, requiring 8,000 bushels-per-day. The volume of waste produced by the process was flushed into Glen Cove Creek where it settled into a layer of foul-smelling organic debris noticeable in Glen Cove and Sea Cliff. With the transformation of the Gold Coast on Long Island's north shore, much of the land that had once grown corn to meet the factory's needs was converted to estates. In 1900, the starch factory closed down its facility and moved to the Midwest. In 1906, its abandoned building burned to the ground.
