Movement Of Bacteria Through Macropores To Ground Water, M. Scott Smith, Grant W. Thomas, Robert E. White
Movement Of Bacteria Through Macropores To Ground Water, M. Scott Smith, Grant W. Thomas, Robert E. White
KWRRI Research Reports
Effects of soil type, flow rate, antecedent soil moisture and other factors on transport of E. coli through soils was measured on disturbed and intact columns 20 cm in diameter by 25 to 30 cm in depth. Added E. coli were distinguished from indigenous microbes using an antibiotic resistance marker. Transport of Cl- and 3H2O was also measured. Up to 96 percent of the bacteria irrigated onto the surface of intact columns were recovered in the effluent. Soil structure appeared to be related to the extent of transport. Columns prepared from mixed, repacked soil were much …
Chemistry Of The Springs Of The Ozark Mountains, Northwestern Arkansas, Kenneth F. Steele
Chemistry Of The Springs Of The Ozark Mountains, Northwestern Arkansas, Kenneth F. Steele
Technical Reports
Three lead-zinc mineralized areas of northern Arkansas were selected to study the effect of mineralization on ground water chemistry. The Ponca area has the largest amount of lead sulfide mineralization, the Zinc area has a significant amount of zinc silicate and zinc sulfide; whereas, the Rush area has zinc carbonate and zinc sulfide. A total of 143 samples were collected from these areas and analyzed for general water chemistry parameters including heavy metal The water quality of the area is generally good; however, a few springs exceed the drinking water standards for ammonia, nitrate, iron, manganese and lead. The surface …
Ground-Water Hydrology And Projected Effects Of Ground-Water Withdrawals In The Sevier Desert, Utah, United States Geological Survey
Ground-Water Hydrology And Projected Effects Of Ground-Water Withdrawals In The Sevier Desert, Utah, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
The principal ground-water reservoir in the Sevier Desert is the unconsolidated basin fill. The fill has been divided generally into aquifers and confining beds, although there are no clearcut boundaries between these units--the primary aquifers are the shallow and deep artesian aquifers. Recharge to the ground-water reservoir is by infiltration of precipitation; seepage from streams, canals, reservoirs, and unconsumed irrigation water; and subsurface inflow from consolidated rocks in mountain areas and from adjoining areas. discharge is by wells, springs, seepage to the Sevier River, evapotranspiration, and subsurface outflow to adjoining areas.
Ground Water In The Southeastern Uinta Basin, Utah And Colorado, United States Geological Survey
Ground Water In The Southeastern Uinta Basin, Utah And Colorado, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
The potential for developing oil-shale resources in the southeastern Uinta Basin of Utah and Colorado has created the need for information on the quantity and quality of water available in the area. This report describes the availability and chemical quality of ground water, which might provide a source or supplement of water supply for an oil-shale industry.
