The investigation evaluated the water quality produced by a 1.0 MGD demonstration water treatment plant EEWTP, which was located adjacent to the Estuary at the Blue Plains WPCP Water Pollution Control Plant, Washington, D.C. Based on certain hydrologic conditions and the results of the EPA Dynamic Estuary Model, a raw water mix of 50 percent estuary water and 50 percent nitrified Blue Plains sewage effluent was selected for treatment. Within the limits of the analytical techniques used and the influent water quality conditions observed it was concluded that the three process combinations monitored were technically feasible of producing a water acceptable for human consumption. Estimated treatment cost for a 200 MGD estuary water treatment plant, using design and operating criteria similiar to that used in the EEWTP, are approximately 34.3 cent1000 gallons for the first alum mode and 47.6 cent1000 gallons for the lime mode of operations. Due to uncertainties over the plants location, intake and certain finished water structures and related costs were excluded from the cost estimates.
