The report describes the environmental effects of alternative municipal wastewater sludge treatment and disposal methods in the Des Moines Integrated Community Area including Polk, Warren, and Marion Counties, Iowa. Eight basic alternatives were considered. The coal mine reclamation alternatives provide the greatest benefit among the project alternatives, followed by land application and landfilling of dewatered sludge. Although the absolute impacts among these alternatives are not that different, improvement of the mine spoil sites results in a much greater site-specific beneficial impact. Land application of liquid sludge would have the greatest negative impact due to adverse socioeconomic factors. Land application of dewatered sludge at agonomic rates is the stated preferred alternative.
