Chesapeake Bay Program: Water Quality
http://www.chesapeakebay.net/wquality.htm
From DLESE Community Collection (DCC)
Comment on this resource
This resource will help students to understand that in the Chesapeake Bay region, waterways support more than 3,000 species of plants and animals, and that healthy water contains a balanced amount of nutrients and normal fluctuations in salinity and temperature. They will also discover that healthy water has plenty of oxygen and little sediment so that underwater living resources can breathe or receive enough sunlight to grow. The site explains that monitoring the changes to the Bay and waterways is important, and the data that is collected can help scientists make determinations about water quality. There is detailed information about water quality factors, including nutrients, sediments, and water temperature. Salinity, dissolved oxygen, and chemical contaminants that can affect the growth, survival and reproducibility of benthic organisms are also explained.
