Description

The National Water-Quality Assessment (NAWQA) Program of the U.S. Geological Survey is the largest water quality program of the Geological Survey, and has, as part of its goals, an understanding of the status and trends of the nation's water quality and an understanding of the natural and anthropogenic factors affecting water quality.

The Sacramento River Basin NAWQA study unit is one of 60 basins, located throughout the United States, which will complete studies of surface water resources, ground water resources and biological assessments. Current activities are described in the following links:

• Sacramento River NAWQA Fact Sheet
• Environmental Setting of Sacramento River Basin and Cycle 1 (1994-1998) Monitoring Network
• Sacramento River NAWQA Scientists
• Surface Water Activities, Cycle 1: 1994-1998
• Ground Water Activities, Cycle 1: 1994-1998
• Biology/Ecology activities, Cycle 1: 1994-1998
• Volatile Chemicals Studies, Cycle 1: 1994-1998
