ABSTRACT
Miscible displacement techniques were used to compare the behavior of deuterium, tritium, and oxygen-18 as water tracers. Displacement of a 170-ml portion of triply tagged water through a 186-cm-long column of water-saturated acidic kaolinitic soil by distilled water revealed no differences in the relative rates of movement of deuterium-, tritium-, and oxygen-18-tagged water.
