Surface water samples were collected on the island of Amchitka, Alaska during the month of June 1997 as part of the Environmental Protection Agency's Long Term Hydrological Monitoring Program. The samples were scanned for the presence of gamma-ray emitting radionuclides and analyzed to determine tritium concentrations. Both conventional and enrichment methods were used. No man made gamma-ray emitters were detected and results of the tritium analyses are consistent with historical values. Trends in decreasing concentration appear to be due to radioactive decay and to dilution.
