Abstract
The chemical water quality in Pool 14 of the Mississippi River below Clinton, Iowa near the Quad‐Cities Nuclear Power Plant, was studied during the period August, 1972 through July, 1974. Variations in river discharge and suspended sediment affected many parameters. Increased discharge resulted in higher levels of total suspended solids, total P, chemical oxygen demand, Fe, Mn, Cu and Zn. The increased suspended solids concentrations were responsible for the higher levels of total P, chemical oxygen demand, Fe, Mn and Cu. Variations in Fe and Mn concentrations correlated strongly with Cu, Pb and Zn. About 90% of the total Fe and Mn concentrations occurred in the suspended solids fraction. Total Hg concentrations did not correlate with either discharge or suspended solids.Keywords
