For safe, long-term storage of radioactive materials in salt beds, rates of solution of salt which might imperil such storage must be known. For solution to continue, fluid must move through the system. Major fluid discharge from the system is by surface streams. Using U.S. Geological Survey records of streamflow and chemical quality of water, computations of sodium chloride discharges of numerous subbasins have been made. A map has been constructed showing tons of sodium chloride discharged per day and tons of sodium chloride discharged per square mile per year. Also shown are locations of major saline springs and their rate of discharge of sodium chloride in tons per day.
