The study was conducted to investigate the ecological effectiveness and economicefficiency of four wastewater treatment plants in East Central Indiana (Muncie, Anderson, Alexandria, and Paws). Data were collected from the four plants, then analyzed descriptively and statistically, and compared in terms of ecological effectiveness and economic efficiency. The Muncie, Anderson, and Paws wastewater treatment facilities were not significantly different from one another in terms of biochemical oxygen demand (BOD5) reductions, but each reduced BOD5 more than the Alexandria facility over the three- year period (1996, 1997, and 1998). Plants were not statistically different regarding suspended solids (SS) reductions. The Muncie, Anderson, and Paws wastewater treatment plants were also not significantly different from one another on ammonia reduction, but each plant reduced ammonia significantly more than Alexandria. Muncie and Anderson were not different from each other on dissolved oxygen (DO) levels, but each had a statistically higher level of DO in the final effluent than Alexandria and Paws. The study showed a statistically significant difference in fecal coliform bacteria abatement between Anderson and Alexandria, Anderson and Paws, and Muncie and Alexandria. Furthermore, Muncie, Anderson and Alexandria were different in terms of cost per 1000 gallons of wastewater treated. Muncie has been treating wastewater at a lower cost than the other treatment plants, whereas Anderson had a higher cost over the three-year period. / Department of Natural Resources and Environmental Management
