During September and October 1987, streambed sediments were collected in the lower Kansas River basin of Kansas and Nebraska as part of the US Geological Survey's National Water-Quality Assessment Program. During a reconnaissance survey, 422 samples were collected on first-order and second-order streams within the study area. Additionally, 62 streambed-sediment samples were collected along the main stem of the Big Blue, and Kansas Rivers and their major tributaries. The 62 samples were collected at least once every 50 stream miles and at sites where trace-element enrichment might be expected based on the location of point-source discharges for which National Pollutant Discharge Elimination System permits have been issued. The less-than 62-micron-sized, sediment fraction was analyzed for 42 major metals and trace elements. In addition, the samples were analyzed for total carbon and carbonate carbon, phosphorus, and sulfur concentrations. The samples collected along the main streams and tributaries also were analyzed for clay content. For 10 of the 47 measured constituents, a majority of sites had values that were considered qualified; that is, the values were less than the lower level of detection for that particular analysis. Concentration of the remaining constituents carried considerably, with aluminum, barium, iron, manganese, and phosphorus havingmore » the largest median concentration. Concentrations of all constituents analyzed are presented and statistically summarized.« less
