Blytheville West WWTP - Mississippi County, Arkansas Wastewater Treatment Plant

Blytheville West WWTP is a municipal wastewater treatment facility located in Mississippi County, Arkansas, serving an estimated population of 5,680 residents. The plant is situated in the Mississippi Alluvial Plain, a region characterized by agricultural activity and proximity to the Mississippi River. As a U.S. facility serving a population under 10,000, the plant is subject to EPA National Pollutant Discharge Elimination System (NPDES) permitting requirements. The plant's treated effluent ultimately drains into the Mississippi River watershed, which flows into the Gulf of Mexico. The receiving waters support diverse aquatic life and are part of a major migratory corridor for birds and fish. Proper treatment helps protect downstream water quality in this ecologically significant basin.

The plant discharges into the Mississippi River basin, which drains a vast area of the central United States before emptying into the Gulf of Mexico. This watershed supports critical habitats for fish, waterfowl, and other wildlife. Nutrient loading from wastewater and agricultural runoff in this region has been linked to hypoxic zones in the Gulf, making effective treatment important for downstream ecosystem health.
