Book Description
Water quality concerns are not new to the Great Lakes. They emerged early in the 20th century, in 1909, and matured in 1972 and 1978. They remain a prominent part of today's conflicted politics and advancing industrial growth. The Great Lakes Water Quality Agreement, under the Boundary Waters Treaty of 1909, became a model to the world for environmental management across an international boundary. Evolution of the Great Lakes Water Quality Agreement recounts this historic binational relationship, an agreement intended to protect the fragile Great Lakes. One strength of the agreement is its flexibility, which includes a requirement for periodic review that allows modification as problems are solved, conditions change, or scientific research reveals new problems. The first progress was made in the 1970s in the area of eutrophication, the process by which lakes gradually age, which normally takes thousands of years to progress, but is accelerated by modern water pollution. The binational agreement led to the successful lowering of phosphorus levels that saved Lake Erie and prevented accelerated eutrophication in the rest of the Great Lakes ecosystem. Another major success at the time was the identification and lowering of the levels of toxic contaminants that cause major threats to human and wildlife health, from accumulating PCBs and other persistent organic pollutants

Book Description
In 1978 Canada and the United States concluded an agreement for the protection and enhancement of water quality in the Great Lakes based on the ecosystem approach to management. Since ratification of this agreement, little progress has been made in practical application of this concept to basin-wide management for the Great Lakes. At the same time public concern for the quality of the Great Lakes and their future has risen dramatically. As a result, the need has arisen for a practical, authoritative explanation of the ecosystem concept. This volume, written by highly qualified authorities, addresses these important ecological, political, and economic issues in a systematic and informative manner. In this study, the ecosystem concept and its objectives are defined. The institutional structure that has evolved for governance of the Great Lakes, the need for a more effective governance structure, and prospects for rehabilitation of the Great Lakes Waters are crucial issues considered. The management question is the single most important policy question with respect to the Great Lakes and this is the only study available that brings together all pertinent information and provides steps for new and constructive management of the Great Lakes.
