What is Eutrophication?

February 19, 2008 Print Friendly and PDF
Eutrophication results when excess nutrients cause excess algae to grow. The algae die and decay. Bacteria cause the decay and consume oxygen. More oxygen is consumed by the bacteria than is produced by the algae. The result is low dissolved oxygen. In addition, excess sediment smothers bottom organisms and blocks sunlight entering the water. These processes result in an environment that can support little life.
