Groundwater Quality In Kentucky: Ph, R. Stephen Fisher
Groundwater Quality In Kentucky: Ph, R. Stephen Fisher
Information Circular--KGS
The parameter pH (the negative base-10 logarithm of hydrogen ion activity, measured in moles per liter) indicates whether a substance will behave as an acid or base. It is one of the most important parameters that describe groundwater quality, because pH largely controls the amount and chemical form of many organic and inorganic solutes in groundwater.
Depth Characterization Of Shallow Aquifers With Seismic Reflection, Part I—The Failure Of Nmo Velocity Analysis And Quantitative Error Prediction, John H. Bradford
Depth Characterization Of Shallow Aquifers With Seismic Reflection, Part I—The Failure Of Nmo Velocity Analysis And Quantitative Error Prediction, John H. Bradford
CGISS Publications and Presentations
As seismic reflection data become more prevalent as input for quantitative environmental and engineering studies, there is a growing need to assess and improve the accuracy of reflection processing methodologies. It is common for compressional-wave velocities to increase by a factor of four or more where shallow, unconsolidated sediments change from a dry or partially watersaturated regime to full saturation. While this degree of velocity contrast is rare in conventional seismology, it is a common scenario in shallow environments and leads to significant problems when trying to record and interpret reflections within about the first 30 m below the water …

Mapped Karst Groundwater Basins In The Lexington 30 X 60 Minute Quadrangle, James C. Currens, Randall L. Paylor, Joseph A. Ray
Map and Chart--KGS
This map shows karst groundwater basins in the Lexington quadrangle, determined primarily by groundwater tracer studies. It can be used to quickly identify the groundwater basins and springs to which a site may drain. Major springs and the relative size of their catchment areas can be evaluated for potential as water supplies. The map also serves as a geographic index to literature on karst groundwater in the area.

Application Of Neuro-Fuzzy Technique+2:9s To Predict Ground Water Vulnerability In Northwest Arkansas, B. Dixon, H. D. Scott, J. V. Brahana, A. Mauromoustakos
Technical Reports
Contamination of ground water has been a major concern in recent years of local, state and federal agencies involved with the management, quality, and quantity of water and their relationships with human health. The Springfield Plateau aquifer, which lies beneath the study area in northwest Arkansas, has been shown to have higher nitrate-N (NO3-N) concentrations than the national median. The dominant landuse (LULC) of this area is agriculture (primarily pasture/cattle and woodlands) and an encroaching urbanization. The major sources of nitrogen in the study area are poultry/cattle wastes, inorganic fertilizers (Peterson et. al., 1998) and septic filter fields. Many of …

Esperance Downs Research Station : Rehabilitation Report, Harvey Jones
Esperance Downs Research Station : Rehabilitation Report, Harvey Jones
Resource management technical reports
Esperance Downs Research Station (EDRS) was established in 1949 as an experimental farm. Knowledge from trials on the station has been instrumental in development of agriculture throughout the Esperance region. However, land degradation and in particular secondary salinity became widespread by the 1980s. With potential for similar problems to develop in the region, the EDRS rehabilitation program began in 1990/91. This report details the objectives of this project along with implementation procedures and an assessment of its achievements.
The stated aim of the rehabilitation was 'To research and demonstrate economic methods of obtaining production from land affected by salinity, waterlogging …
