Overview
Greenfield Lagoon serves Weakley County, Tennessee, treating wastewater for approximately 2,273 residents. The plant operates under U.S. EPA and Tennessee Department of Environment and Conservation regulations.
Greenfield Lagoon is a wastewater treatment facility located in Weakley County, Tennessee, within the West Tennessee region. The plant serves a population of about 2,273 people, reflecting a small community-scale operation typical of rural areas in the state. As a lagoon-based system, the plant likely provides secondary treatment through natural biological processes, consistent with common practices for small agglomerations in the United States. Under the Clean Water Act, such facilities are regulated by the National Pollutant Discharge Elimination System (NPDES) permit program, administered in Tennessee by the Tennessee Department of Environment and Conservation (TDEC). These permits set effluent limits to protect water quality. The plant discharges treated wastewater into local waterways that drain into the Mississippi River basin, ultimately reaching the Gulf of Mexico. The surrounding area is part of the West Tennessee agricultural landscape, where surface waters support diverse aquatic life and are used for recreation and irrigation. Proper treatment helps maintain the ecological health of these streams and the larger Mississippi River system.
Environmental context
Greenfield Lagoon discharges into tributaries of the Mississippi River, which flows into the Gulf of Mexico. The receiving waters support aquatic ecosystems including fish and macroinvertebrates, and are part of a watershed that provides habitat for migratory birds and other wildlife. The plant's treatment helps reduce nutrient loading, which is critical for mitigating hypoxia in the Gulf of Mexico.
