This study assessed the impacts of waste discharges from a large water treatment plant on Mississippi River sediments. During the cleaning of two basins, the waste discharge increased the iron, aluminum, moisture, and organics content and changed the particle size distribution of the sediments. The influence of the discharge was confirmed to an area 100 ft (30 m) offshore and within 3,300 ft (990 m) downstream of the waste outfall. No measurable effects from the discharge were found one week after cleaning of the basins. Includes 15 references, tables, figures. See more
