Ground-water investigations at U.S. Air Force Launch Control Facility E-0, Ramsey County, North Dakota

U.S. Air Force Launch Control Facility E-0 is located in Ramsey County, North Dakota. Geohydrologic and water-quality data indicate that the fractured Pierre Shale is the only aquifer in the vicinity of the facility that will supply acceptable water at the required rate of 5 gallons per minute (0.32 liters per second}. The chemical quality of the water is generally considered marginally satisfactory for the intended use due to the presence of high concentrations of dissolved solids, and chloride or sulfate.
