Evaluation of a predictive ground-water solute-transport model at the Idaho National Engineering Laboratory, Idaho. Water-resources investigations (final). [Aqueous chemical and radioactive wastes]

Aqueous chemical and radioactive wastes discharged to shallow ponds and to shallow or deep wells on the Idaho National Engineering Laboratory (INEL) since 1952 have affected the quality of the ground water in the underlying Snake River Plain aquifer. The aqueous wastes have created large and laterally dispersed concentration plumes within the aquifer. The waste plumes with the largest areal distribution are those of chloride, tritium, and with high specific conductance values. The data from eight wells drilled near the southern INEL boundary during the summer of 1980 were used to evaluate the accuracy of a predictive modeling study completed in 1973 that simulated 1980 positions of the chloride and tritium waste plumes.
