| Summary |
"The ever increasing use of water and unabated pollution of streams have made necessary increased research efforts into the quality and quantity of the available national water resources. Karst terrain is prevalent in several sections of the United States, however, little work has been done on the effect of this topography on water quality. The purpose of this investigation was to determine the effect of carbonate karst terrain on the quality of water. The Meramec spring area, east of Rolla, Missouri, was selected for study. This area was underlain with dolomite formations and contains both karst and non-karst drainage basins which made possible comparative studies. Stream, well, and spring waters from the study area were characterized using chemical, physical, and bacteriological determinations and the results obtained were evaluated. Water in carbonate karst terrain was found to contain primarily calcium and magnesium bicarbonate, with nitrate ions and iron often reaching significant concentrations in underground supplies. Increases in the mineral content of stream waters at some locations after rainfall indicated that subsurface discharges were feeding the streams. Direct pathways from the surface to the groundwater were established. when coliform organisms were found in the spring and well water samples"--Abstract. |
