Book Description
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.

Book Description
This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.

Book Description
The study covers the period from 1965 (base year) to the year 2020. In order to identify and stage early, intermediate, and late action programs, this study was divided into three time frames: 1966-1980, 1981-2000, and 2001-2020. This study deals with the water and related land resources of the Lower Colorado Region and embraces all significant problems and beneficial uses associated with these resources. Consideration was given to various aspects of problems related to supplies of water for municipal and industrial purposes, water quality control, flood control, irrigation, electric power production, mining and mineral processing, watershed management and treatment, land resources and use, outdoor recreation, and fish and wildlife. Environmental aspects such as natural beauty, cultural and historic values, rare species of flora and fauna, wildlife in general, and water and air quality goals are considered to be integral parts of the fabric of an optimum framework program.
