This study was conducted because the multiagency program called the Valleywide Fish Tissue Screening Study found relatively high concentrations of PCBs and chlordane in fish from Nickajack Reservoir. Fish to be analyzed for this program are collected from Tennessee River reservoirs once every three years as long as concentrations of contaminants remain low. A more indepth study is undertaken if concentrations are sufficiently high to pose a potential threat to human health or the environment. Results from the initial year (1987) of the Valleywide Fish Tissue Screening Study found sufficiently high concentrations of both PCBs and chlordane in catfish (the indicator species) from Nickajack Reservoir to warrant attention. Concentrations of these chlorinated organics exceeded the predetermined Tier 3 levels established to trigger a more indepth study to better define apparent problems. The five-catfish fillet composite sample from the lower reservoir location (Tennessee River mile 425) contained 1.9 {mu}g/g total PCBs and 0.21 {mu}g/g chlordane, while the composite sample from the upper area (TRM 457) contained 1.3 {mu}g/g PCBs and 0.25 {mu}g/g chlordane. 4 refs., 7 tabs.

TVA analyzes tissues of Tennessee Valley area fish as part of intensive evaluations and as pat of screening level evaluations. Intensive studies are conducted in reservoirs where contamination problems are known or suspected and include analysis of individual fillets from important fish species from several areas in the reservoir. This information is used by State public health officials to determine whether fish consumption advisories are necessary to protect human health. Screening studies are based on analysis of composite rather than individual samples and are intended to provide trend information and to identify areas where problems may exist indicating need for an intensive evaluation. All studies are coordinated with State agencies because they ultimately must make management decisions regarding public health. TVA has two fish tissue screening programs. One examines fish on an annual basis at inflow points from eight of the major tributaries into the Tennessee River reservoir system. The other examines fish from within the reservoirs on a rotating basis with the goal of sampling each reservoir at least once every three years. 7 refs., 1 fig., 8 tabs.

Groundwater is extremely important to Madison County as it provides nearly three quarters of the county's drinking water. In recent years, Madison County has increasingly recognized the need to protect its groundwater resource. A supply of usable groundwater is one element of a high quality environment, which can help spur economic development and provide for the needs of a growing population. Without planning protection and understanding of possible consequences, however, economic development and population pressures can cause a gradual degradation of groundwater. In April 1987, the Tennessee Valley Authority (TVA) convened a local groundwater steering group in Madison County. At the first meeting the ground agreed upon these goals: (1) to seek incorporate groundwater protection into the planning and development process for Madison County, (2) to support efforts by Madison County to obtain authority to adopt zoning ordinances and subdivision regulations, and (3) to develop a groundwater management plan for the county. This report provides essential information needed in developing a plan and is based on the following assumptions: the citizens of Madison County value the environment in which they live and wish to protect it from pollution; continued economic development is necessary for a healthy local economy; and a …
