Analyses for radionuclides in the leachate from ten special wasteform lysimeters at the Savannah River Plant (SRP) have continued since January 1983. These included monthly analyses of lysimeter sump leachate for gamma-emitting radionuclides, and quarterly analyses of sump leachate for Sr-90 and of lysimeter soil moisture samples for gamma emitters. Cobalt-60 and Sr-90 continue to be the most abundant radionuclides detected in sump leachate from the lysimeters. Cesium-137 continues to occur regularly in the sump of one portland cement wasteform lysimeter, and sporadically in the sump of one other. Cesium-137 remains below detection limits at all of the polymer wasteform lysimeters, in both the monthly sump leachate and quarterly soil moisture samples. Results indicate that the polymer wasteforms retain Co-60 better by a factor of 100 than do the portland cement wasteforms. However, the portland wasteforms retain Sr-90 better by a factor of 10 than do the polymer wasteforms. No new radionuclides were detected at the lysimeters during the past year. 7 refs., 12 figs., 15 tabs.
