Groundwater management and protection Madison County, Alabama

Description: 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 … more

The effect of the use of plastic sampling containers on laboratory measurements of dissolved oxygen

Description: Dissolved oxygen (DO) concentrations are often used to define the water quality of a stream or reservoir. In the Tennessee Valley, there is a commonly held belief that water quality in general, and DO in particular, is declining in TVA reservoirs. In 1980, TVA conducted a study of DO trends in the tailraces of Tennessee River Dams and found a downward trend in most reservoirs, with the greatest decrease in the downstream reservoirs. This report examines a change in sampling procedures which may… more

Water resources review: Wheeler Reservoir, 1990

Description: Protection and enhancement of water quality is essential for attaining the full complement of beneficial uses of TVA reservoirs. The responsibility for improving and protecting TVA reservoir water quality is shared by various federal, state, and local agencies, as well as the thousands of corporations and property owners whose individual decisions affect water quality. TVA's role in this shared responsibility includes collecting and evaluating water resources data, disseminating water resources… more

Evaluation of the water quality in the releases from thirty dams in the Tennessee River Valley

Description: The Tennessee Valley Authority (TVA) has routinely monitored dissolved oxygen (DO) and temperature from the tailwater releases of its dams since the 1950s. The original objective of this monitoring was to collect baseline information to support reaeration research and determine the relative impact of impoundments on the assimilative capacity of the river system. This monitoring has continued even though the original objective was satisfied. New purposes for this monitoring data have arisen in s… more

Approaches to verification of two-dimensional water quality models

Description: The verification of a water quality model is the one procedure most needed by decision making evaluating a model predictions, but is often not adequate or done at all. The results of a properly conducted verification provide the decision makers with an estimate of the uncertainty associated with model predictions. Several statistical tests are available for quantifying of the performance of a model. Six methods of verification were evaluated using an application of the BETTER two-dimensional wa… more

Water quality investigation of Kingston Fossil Plant dry ash stacking

Description: Changing to a dry ash disposal systems at Kingston Fossil Plant (KFP) raises several water quality issues. The first is that removing the fly ash from the ash pond could alter the characteristics of the ash pond discharge to the river. The second concerns proper disposal of the runoff and possibly leachate from the dry ash stack. The third is that dry ash stacking might change the potential for groundwater contamination at the KFP. This report addresses each of these issues. The effects on the … more

PCB studies on fish from Watts Bar, Fort Loudoun, Tellico, and Melton Hill Reservoirs, 1988

Description: The Tennessee Valley Authority (TVA) reservoirs that are the subject of this report have been under investigation for several years due to contamination with polychlorinated biphenyls (PCBs). The study has two primary objectives: (1) define the geographical boundaries where contamination in fish ceases to be a problem and (2) determine the trend in PCB loading in fish from reservoirs where the contamination has been well defined. The purpose of this document is to briefly describe results of PC… more

South Fork Holston River basin 1988 biomonitoring

Description: There is concern over the effects of shifts in land use use practices on the aquatic fauna of streams in the South Fork Holston River basin in northwestern North Carolina and southwestern Virginia. Trout reproduction has noticeably declined in the Watauga River subbasin. The Watauga River and Elk River subbasins have been subjected to commercial and resort development. The Middle fork Holston River and the upper South Fork Holston River subbasins have been affected by agricultural and mining ac… more
