Ground-Water Data Network - Arkansas
Short Title: Ground-Water Data Network
Project Chief: Anna Nottmeier
Cooperators: Arkansas Department of Agriculture-Natural Resources Division, Arkansas Geological Survey, Cabot Water Works, Grand Prairie Water Users Association, Natural Resources Conservation Services, Union County Conservation District
Project Time Frame: 1985 - present
Arkansas is the fourth largest user of ground water in the United States. Since the 1920’s, ground-water withdrawals have increased while water levels have declined. Long term water-level records are needed to evaluate the effects of climatic variations on the recharge and discharge from ground-water systems and are necessary in the construction and calibration of accurate ground-water flow models to allow prediction of future conditions.
The purpose of the ground-water data network study is to collect hydrogeologic and water-level data sufficient to provide a long-term database so that the general response of the hydrologic system to natural climatic variations and induced stresses is known and potential problems can be defined for management of the resource.
The study collects and maintains water levels from the U.S. Geological Survey and State and County agencies. Several reports are produced each year that show water-level altitudes which are used to construct potentiometric-surface maps that define the water-level depressions and the direction of water flow within the aquifer. These reports also present continuous and long-term water-level data that show rates of rise/decline through time. Geophysical logging techniques are performed on selected wells to define the depth and thickness of various aquifers. Aquifer tests are conducted to provide storage and transmissivity coefficients that describe the amount of water available and the rate of flow within the aquifer. Ground-water quality samples are collected to define the potential uses for water and indicate changing conditions within the aquifer.
