Leola WWTP - Secondary Wastewater Treatment in Leola, Arkansas

Leola WWTP is a municipal wastewater treatment plant located in Leola, Grant County, Arkansas, United States. The facility serves a small population of 501 residents, reflecting its role in a rural community. The plant is situated on Shannon Drive and operates under the regulatory framework of the U.S. Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level for small communities in the United States. Its designed capacity is 378.54 cubic meters per day, and it currently discharges an average of 189.27 cubic meters per day, indicating operational capacity well within design limits. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local waterway, likely a tributary of the Ouachita River or the Arkansas River basin. The plant's inland location, over 50 kilometers from the coast, means its discharge affects freshwater ecosystems rather than marine environments. The surrounding area is predominantly rural, with agriculture and forestry as primary land uses, influencing the local watershed's water quality.

The plant's discharge enters a local stream that flows into the Ouachita River, part of the Mississippi River basin, ultimately reaching the Gulf of Mexico. The watershed supports diverse aquatic life, including fish and macroinvertebrates, and is important for regional water supply and recreation. The rural setting means the plant's nutrient and pollutant loads can affect downstream water quality, particularly in sensitive areas like the Mississippi River Delta.
