Dredging America's Waterways and Harbors: More Information on Environmental and Economic Issues

The effects that dredging and disposing of dredged material will have on the environment have come into sharper focus within the last decade. As a result, the Army Corps of Engineers has been required by legislation, litigation, and regulations to modify its practices. The Corps has undertaken a research program and changed its dredging practices at certain locations, but at much higher costs. The research is still incomplete, and the cause-and-effect relationships between materials considered contaminated and significant damage, especially long-term damage, have not been determined. Before appropriating funds for channel maintenance projects, the Congress needs adequate information on the tradeoffs between economic and environmental values.
