The goals of the National Water-Quality Assessment (NAWQA) Program are to assess the status and trends in the quality of the Nation's ground- and surface-water resources and to develop an understanding of the natural and human factors affecting water quality. Consistent data collection and analysis methods throughout 59 of the Nation's most important river and aquifer systems provide uniform and comparable information to address water-quality concerns at local, regional, and national scales. The study design of the lower Tennessee River Basin NAWQA incorporates surface-water, ecological, and ground-water studies to help understand water-quality conditions and issues affecting the lower Tennessee River Basin.
The surface-water component consists of nine stream sites located throughout the lower Tennessee River Basin. Water-quality samples will be collected at these sites on a monthly basis and during selected storm events for about two years. Water-quality samples will be analyzed for major ions, nutrients, and suspended sediment. At one site, water-quality samples will be collected on a weekly basis during the growing season and analyzed for pesticides. Ecological studies will be conducted at all sites to describe relations between water quality and the aquatic biological community. Ecological studies include aquatic and riparian habitat assessments and annual surveys of fish and benthic invertebrate communities. The ground-water component consists of sampling about 30 shallow domestic wells in both the Eastern Highland Rim and the Central Basin. These wells will be sampled for major ions, nutrients, pesticides, trace elements, bacteria, and volatile organic compounds. Additionally, about 30 shallow wells will be drilled in agricultural areas within the Eastern Highland Rim. These wells will be sampled for major ions, nutrients, and pesticides.
