National Water Quality Assessment Program (NAWQA) in Tennessee

About the Louisiana Water Science Center Office Locations What We Do Data Collection Database Capabilities

SPARROW, a modeling tool for the regional interpretation of water-quality monitoring data. The model relates in-stream water-quality measurements to spatially referenced characteristics of watersheds, including contaminant sources and factors influencing terrestrial and aquatic transport. SPARROW empirically estimates the origin and fate of contaminants in river networks and quantifies...

The National Water-Quality Assessment (NAWQA) Program is designed to describe the status and trends in the quality of the Nation's surface-water and ground-water resources and to provide a sound understanding of the natural and human factors that affect the quality of these resources. As part of the program, investigations will be conducted in approximately 60 areas -- called study units --...

Welcome....the Lower Tennessee River Basin in Tennessee, Alabama, Georgia, Kentucky, and Mississippi is one of the 59 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program.The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources...

The Mobile River Basin study is one of several NAWQA studies that began in Federal fiscal year 1997 (October 1996). Study planning and design, and analysis of existing data will be done during the first 2 years, which is consistent with all NAWQA studies. After the 2-year planning period, surface- and ground-water and biological data will be collected intensively for 3 years during a high...
