For three decades, scientists collected a large and convincing body of evidence demonstrating that toxic pollutants released to the air can be deposited at locations far from their original sources. In 1990, Congress amended the Clean Air Act and included provisions that established research and reporting requirements related to the deposition of hazardous air pollutants to the ¿Great Waters.¿ The water bodies designated by these provisions are the Great Lakes, Lake Champlain, and Chesapeake Bay and certain other coastal waters. This atlas provides basic information about the Great Waters, their water quality problems, and the issue of atmospheric deposition to aquatic ecosystems in general. Color photos and maps.

On November 15, 1990 the U.S. Congress amended the Clean Air Act and included provisions that established research and reporting requirements related to the deposition of hazardous air pollutants to the Great Waters. The waterbodies designated by these provisions are the Great Lakes, Lake Champlain, Chesapeake Bay, and certain other coastal waters. The Office of Air Quality and Standards of the U.S. Environmental Protection Agency (EPA) provides access to the full-text versions of the three reports (1994, 1997, 2000) that have been submitted to the U.S. Congress in this area.

The essential, cornerstone book of modern environmentalism is now offered in a handsome 40th anniversary edition which features a new Introduction by activist Terry Tempest Williams and a new Afterword by Carson biographer Linda Lear.

The U.S. Environmental Protection Agency was created to protect public health and the environment, and it has traditionally emphasized its regulatory mission over its scientific mission. Yet for environmental policy to be credible with the public and policymakers, EPA's actions must have a sound basis in science. In Science at EPA, Mark Powell offers detailed case studies that map the origins, flow, and impact of scientific information in eight EPA decisions involving the agency's major statutory programs. Drawing on extensive research and interviews, he provides the most comprehensive examination available on the acquisition and use of science in environmental regulation. Powell describes the key obstacles to the practical, efficient, and effective acquisition and use of knowledge in what is a crucial, but complex endeavor. His book is an essential contribution for practitioners, scholars and students, and citizens who are determined to protect our environment rationally and effectively.
