Since deactivation of the last once-through cooling production reactor in January 1971, radioactivity associated with sediments or biota in the Columbia River attributable to past Hanford operations decreased to very low levels. Currently only a few long-lived radionuclides are measurable and generally due to the association of these radionuclides with sediments in the river. The data available from several different monitoring programs provide a preliminary description of the extent, concentration, and physical form of these radionuclides. Data are presented on $sup 137$Cs, $sup 60$Co, $sup 65$Zn, and $sup 152$Eu in sediments sampled in 1974. (CH)
