Description: Shallow land burial in humid regions as a disposal method for low-level solid waste provides the potential for water-driven migration of leachable radionuclides present in the waste. A number of methods to control this migration have been suggested and studied. One such method involves the use of a dc electric current to move ions countercurrent to the water flow. Laboratory studies using trays of soil indigenous to the Oak Ridge National Laboratory (ORNL) low-level burial grounds have shown /sup 137/Cs, /sup 90/Sr, and /sup 99/Tc ions can be moved countercurrent to a water flow using small dc currents of 20 mA at 40 volts. A field test of the method has been under way for over one year in an ORNL low-level waste disposal area. Results of the field test are given in this paper.
