Analyses of sediment and water samples collected down stream from phosphate sources disclosed a removal of phosphates by both sediments and suspended inorganic materials. The phosphates are recycled by bacteria, aquatic plants, and stream degradation. The discharge of sewage and industrial refuse in the lower Huron River increased phosphate content in both water and sediments. The development of algal slimes was paralleled by a reduction in the diversity of aquatic organisms, and in some instances climaxed in the formation of mud-ooze sediments that support only limited benthos. Fixation of phosphorus by ashed sediments is the only method removing phosphates from waste waters.
