National Water-Quality Assessment (NAWQA) Program
Potomac River Basin Study Unit
In 1991, the U.S. Geological Survey (USGS) began to implement a full-scale
National Water-Quality Assessment (NAWQA) program. The long-term goals
of the NAWQA program are to describe the status and trends in the quality
of a large, representative part of the Nation's surface-water and ground-water
resources and to provide sound, scientific understanding of the primary
natural and human factors affecting the quality of these resources. In
meeting these goals, the program will produce a wealth of water-quality
information that will be useful to policy makers and managers at the national,
State, and local levels.
The Potomac study units first high-intensity phase began in 1991 and
ended in 1995, one of nineteen across the country. By 1997, the NAWQA program
consisted of 60 study units investigating major river basins and aquifer
systems that will account for about one-half of the Nation's land area
and two-thirds of the Nation's water use and population. Currently, the
Potomac study unit is in the low-intensity phase of the program.
