Mammoth Spring WWTP, Fulton County, Arkansas - Advanced Treatment Facility

Mammoth Spring WWTP is a wastewater treatment facility located in Fulton County, Arkansas, United States. It serves a small population of 977 residents, reflecting its role in a rural community. The plant is situated inland, away from coastal influences, and operates under the regulatory framework of the US Clean Water Act, which governs discharges to surface waters. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 454.25 units and an actual discharge volume of 363.40 units, the plant operates below its capacity, indicating room for future growth. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Arkansas Department of Energy and Environment, which set effluent limits to protect water quality. The treated effluent from Mammoth Spring WWTP likely discharges into a local waterway within the Mississippi River basin, which ultimately drains to the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's streams and rivers.

The plant discharges into a local water body within the Mississippi River basin, which flows into the Gulf of Mexico. The region supports diverse aquatic life, including fish and macroinvertebrates, and the advanced treatment helps minimize nutrient loading that could contribute to hypoxia in the Gulf. The facility's inland location reduces direct marine impact, but its discharge still influences downstream water quality.
