Relationship Between Ground And Surface Water Quality In Karst Systems, Richard L. Meyer
Relationship Between Ground And Surface Water Quality In Karst Systems, Richard L. Meyer
Technical Reports
Springs in Northwest Arkansas may originate from relatively small fractures in rock strata or from cave systems. The water emerging from these springs is frequently used as water sources for plants, animals and humans. The quality of the ground water source and the emerging water are uncertain and frequently unknown. In addition, the opportunity to monitor changes in water quality during flow from origin (water entering the cave) to emergence is uncommon. Cave systems with definable drainage basins and accessible sampling points near the midpoint of the cave are also uncommon. Examining the interface between the quality of surface water …

Fact Sheet No.2: Water Quality And Poultry Disposal Pits, T. C. Daniel, D. R. Edwards, D. J. Nichols, K. F. Steele, Steve Wilkes
Technical Reports
Disposing of poultry that die during grow out is a serious management problem for poultry producers in Northwest Arkansas and across the country. Poultry disposal can affect water quality and the health of wildlife, livestock and people.
Evaluation Of The Water Quality Impacts Of Land Application Of Poultry Litter, T. C. Daniels, D. R. Edwards
Evaluation Of The Water Quality Impacts Of Land Application Of Poultry Litter, T. C. Daniels, D. R. Edwards
Technical Reports
Evaluating the effect of land application of animal waste on water quality is fraught with inherent variability due to differing infiltration rates, slope, rainfall intensity and etc . Simulated rainfall technology has been used in erosion research for decades. Generally, this technology is used on plots of sufficient size (25 x 5 m) to develop rill and interrill erosion. The object of this investigation was to adapt and modify existing rainfall simulation technology used in soil erosion research for use in evaluating water quality impacts of land application of animal waste, and to test, evaluate and demonstrate it's scientific validity. …
Effect Of Land Application Of Poultry Waste On Pesticide Loss, T. C. Daniel, D. R. Edwards
Effect Of Land Application Of Poultry Waste On Pesticide Loss, T. C. Daniel, D. R. Edwards
Technical Reports
The poultry industry in Arkansas is a large, concentrated, growing industry that produces a high volume of fecal waste. Most of this waste is surface applied as pasture fertilizer. Pesticides are commonly used in the poultry industry for fly and litter beetle contro land are often a component of the surface-applied poultry waste. No information exists in the scientific literature regarding the transport of this pesticide component to nearby water supplies.Our research focused on cyromazine, a feed-through larvicide used to control flies in caged-layer hen houses. Tetrachlorvinphos and carbaryl are also used in poultry waste, but these pesticides have a …
Fact Sheet No.1: Nonpoint Source Pollution And Water Quality Of Northwest Arkansas, T. C. Daniel, D. R. Edwards, D. C. Wolf, K. F. Steele, M. J. Cochran
Fact Sheet No.1: Nonpoint Source Pollution And Water Quality Of Northwest Arkansas, T. C. Daniel, D. R. Edwards, D. C. Wolf, K. F. Steele, M. J. Cochran
Technical Reports
Preservation of a clean, safe, and biologically diverse environment can capture public attention as few other issues can. Indeed, recent international cooperative efforts indicate that there is an increasing global desire to pass on to future generations an environment at least equal in quality to the one we inherited.
