Preliminary Study of Wastewater Movement in Yellowstone National Park, Wyoming, October 1976 Through September 1977
Cox ER. 1979. Preliminary Study of Wastewater Movement in Yellowstone National Park, Wyoming, October 1976 Through September 1977. U.S. Geological Survey (USGS) Open-File Report. 79-684. Cheyenne, WY
This report describes hydrologic data collected and some preliminary interpretations for a study by the U.S. Geological Survey in cooperation with the National Park Service to determine the effects on nearby lakes and streams of wastewater effluents that percolate from sewage lagoons at four sites in Yellowstone National Park. A network of observation wells has been established near the sites, and water-level and water-quality data have been collected. Ground-water mounds have built up under the lagoons as percolation of effluents occurred. Percolating effluents mix with ground water and move down the hydraulic gradient in a direction generally perpendicular to the water-level contours. Chloride and sulfate concentrations and specific conductance of water in wells, and water-level contours indicate the most likely areas and directions of movement of percolating effluents, The most likely directions of movement are: Fishing Bridge, southwestward toward the Yellowstone River; Old Faithful, northward and northeastward toward Iron Spring Creek; Madison Junction, southeastward toward the Madison River; and Grant Village, northward toward Yellowstone Lake, northwestward, and westward.
