Effective Surface Water Quality Policies: A Contrast of Policies in the United States and the European Union

The United States and the European Union each have their own policy approach to protect surface water quality. Both policy approaches are similar in many ways. Both rely heavily on command and control. However, there are differences in the application of the details. Both the U.S. and E.U. began current efforts to protect surface water quality in the 1970s, yet quality continues to less than desired in both places. Both have reduced point source pollutants but have had difficulty controlling non-point source pollutants even though policies have been in place for many decades. The successes and failures of the two policies are studied in this project to determine which aspects of both policies will best protect surface water quality in an increasingly complex future.

Review of Desalination and Concentrate Management Issues for Increasing Drinking Water Supplies

Water quantity and quality issues worldwide are causing nations to consider alternate sources for drinking water. Desalination and other membrane processes for treatment of seawater and brackish inland waters have been in use for the past quarter century and are growing in use worldwide. These treatment processes create a highly concentrated waste stream in which the principal constituents are dissolved solids. This report provides an overview of desalination methods and the methods available to dispose of this waste stream. Innovative technologies being studied for possible future use are also discussed.
