National Water-Quality Assessment (NAWQA) Projects in Minnesota
The National Water-Quality Assessment (NAWQA) Program is designed to describe the status and trends in the quality of the Nation's surface- and ground-water resources and to provide a sound understanding of the natural and anthropogenic factors that affect the quality of these resources. As part of the program, investigations are conducted in 59 areas called "study units" throughout the Nation to provide a framework for national and regional water-quality assessment. Regional and national synthesis of information from study units consist of comparative studies of specific water-quality issues using nationally consistent information.
