In 1991, the USGS began full implementation of the program. The NAWQA Program builds upon an existing base of Robert M. Hirsch water-quality studies of the USGS, as well as those of Chief Hydrologist other Federal, State, and local agencies. The objectives of the NAWQA Program are to: •Describe current water-quality conditions for a large part of the Nation’s freshwater streams, riv- ers, and aquifers. •Describe how water quality is changing over time. •Improve understanding of the primary natural and human factors that affect water-quality conditions.
