Blairstown WWTP - Secondary Wastewater Treatment in Blairstown, Iowa

Blairstown WWTP is a municipal wastewater treatment plant located in Blairstown, Iowa, United States. The facility serves a small population of 682 residents, typical of a rural agglomeration in the Midwest. It is situated in Benton County, within the state's agricultural landscape. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal facilities of this scale. Secondary treatment uses biological processes to remove organic matter and suspended solids. The plant's designed capacity is 1,044.77 cubic meters per day, and it currently discharges an average of 984.21 cubic meters daily, indicating it operates below capacity. The treated effluent is discharged into a local water body, likely a tributary of the Iowa River or directly into the river itself, which flows southeast to the Mississippi River. This discharge contributes to the overall water quality of the Mississippi River Basin, a major ecological and economic resource. The plant's operation helps protect downstream aquatic habitats and supports the region's water quality goals.

The plant discharges into a receiving water body within the Mississippi River Basin, which ultimately drains into the Gulf of Mexico. The local watershed supports diverse aquatic life and is part of a larger network of rivers and streams that provide habitat for fish and migratory birds. Proper treatment is essential to prevent nutrient pollution, which can contribute to hypoxia in the Gulf of Mexico.
