Marshall WWTP is a municipal wastewater treatment facility located in Marshall, Searcy County, Arkansas. It serves a small community of about 1,355 people, typical of rural treatment plants in the Ozark region. The plant is situated inland, far from coastal waters, and its operations are governed by state and federal regulations. As a small-scale facility in the United States, Marshall WWTP operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. Plants of this size commonly employ secondary treatment or lagoon systems to meet regulatory standards. The treated effluent from Marshall WWTP likely discharges into a tributary of the Buffalo National River or the White River system, both of which are ecologically significant. The Buffalo National River is a free-flowing stream known for its biodiversity and recreational value, while the White River supports diverse aquatic life and flows into the Mississippi River, ultimately reaching the Gulf of Mexico.
Environmental context
Marshall WWTP discharges into the watershed of the Buffalo National River, a pristine Ozark stream that flows into the White River. The White River is a major tributary of the Mississippi River, which empties into the Gulf of Mexico. This watershed supports diverse aquatic species, including threatened mussels and fish, and is an important corridor for migratory birds. Protecting water quality in this region is critical for maintaining the ecological health of the Buffalo National River and downstream habitats.
