Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
The United States Government Printing Office (GPO) was created in June 1860, and is an agency of the the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. The Coastal Zone Information Center (CZIC) collection provides access to nearly 5,000 coastal related documents that the U.S. Government Printing Office (GPO) received from the National Oceanic and Atmospheric Administration (NOAA) Central Library. The collection provides almost 30 years of data and information crucial to the understanding of U.S. coastal management and NOAA's mission to sustain healthy coasts. This is one of their documents.
Committee Serial No. 90-79. Considers H.R. 25, to authorize an Interior Dept inventory and study of the nation's estuaries, and S. 695, and similar S. 2365, to protect, preserve, restore, develop, and make accessible the nation's estuary areas.
Excerpt from Governance of Non-Point Source Inputs to Narragansett Bay: A Plan for Coordinated Action The United States Congress created the National Estuary Program in 1984, citing its concern for the "health and ecological integrity" of the nation's estuaries and estuarine resources. Narragansett Bay was selected for inclusion in the National Estuary Program in 1984 and designated an "estuary of national significance" in 1988. The Narragansett Bay Project (Nbp) was established in 1985. Under the joint sponsorship of the U.S. Environmental Protection Agency and the Rhode Island Department of Environmental Management, the Nbp's mandate is to direct a five-year program of research and planning focussed on managing Narragansett Bay and its resources for future generations. The Nbp will develop a comprehensive management plan by December, 1990, which will recommend actions to improve and protect the Bay and its natural resources. The Nbp has established the following seven priority issues for Narragansett Bay: * management of fisheries * nutrients and potential for eutrophication * impacts of toxic contaminants * health and abundance of living resources * health risk to consumers of contaminated seafood * land-based impacts on water quality * recreational uses The Nbp is taking an ecosystem approach to address these problems and has funded research that will help to improve our understanding of various aspects of these priority problems. The Project is also working to expand and coordinate existing programs among state agencies, governmental institutions, and academic researchers in order to apply research findings to the practical needs of managing the Bay and improving the environmental quality of its watershed. This report represents the technical results of an investigation performed for the Narragansett Bay Project. The information in this document has been funded wholly or in part by the United States Environmental Protection Agency under assistance agreement #Cx812680 to the Rhode Island Department of Environmental Management. It has been subject to the Agency's and the Narragansett Bay Project's peer and administrative review and has been accepted for publication by the Management Committee of the Narragansett Bay Project. The results and conclusions contained herein are those of the author(s), and do not necessarily represent the views or recommendations of the Nbp. Final recommendations for management actions will be based upon the results of this and other investigations.
