[en] Analytical data for surface-water samples taken from 16 sampling sites are presented. A statistical treatment of the data showing histograms and frequency distributions, is also included. Samples were collected in the spring and summer of 1975 as part of a water and stream-sediment study to establish methods of sampling for uranium and other elements in surface waters. Stream sediments have been collected along with water samples at each site, and a similar statistical study of the corresponding data for sediment samples is in progress
