This volume explores the issues associated with the complex subject of water quality protection in an assessment of the successes and failures of the Clean Water Act over the past twenty years. In addition to examining traditional indicators of water quality, the authors consider how health concerns of the public have been addressed, and present a detailed examination of the ecological health of our waters. Taken together, these measures present a far more complete and balanced picture than raw water quality data alone.
As well as reviewing past effectiveness, the book includes specific recommendations for the reauthorization of the Act, which is to be considered by Congress in 1995. This balanced and insightful account will surely shape the debate among legislative and policy experts and citizen activists at all levels who are concerned with issues of water quality.
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
In Sinking Chicago, Harold Platt shows how people responded to climate change in one American city over a hundred-and-fifty-year period. During a long dry spell before 1945, city residents lost sight of the connections between land use, flood control, and water quality. Then, a combination of suburban sprawl and a wet period of extreme weather events created damaging runoff surges that sank Chicago and contaminated drinking supplies with raw sewage.
Chicagoans had to learn how to remake a city built on a prairie wetland. They organized a grassroots movement to protect the six river watersheds in the semi-sacred forest preserves from being turned into open sewers, like the Chicago River. The politics of outdoor recreation clashed with the politics of water management. Platt charts a growing constituency of citizens who fought a corrupt political machine to reclaim the region’s waterways and Lake Michigan as a single eco-system. Environmentalists contested policymakers’ heroic, big-technology approaches with small-scale solutions for a flood-prone environment. Sinking Chicago lays out a roadmap to future planning outcomes.
