USGS Water Science Centers are located in each state.
During 1998-2001, chemical, physical, and biological data were collected from selected areas on local and regional scales to describe the quality of water throughout the study unit. Measurements were made to determine water chemistry in streams and aquifers; the quantity of suspended sediment and the quality of bottom sediments in streams; the variety and number of fish, benthic invertebrates, and algae in streams; and the presence of contaminants in fish tissues. Individual streams and aquifers, chemical constituents, and biological species were selected for sampling to represent the important water resource and water-quality concerns in the Mobile River Basin and the Nation.
The sampling components were divided into 5 major sampling networks:
