Water Quality Reports

The Ohio Environmental Protection Agency – Division of Surface Water performed a water quality study covering over 55 miles of the upper Mahoning River and selected tributaries in 2006. From June to October of that year, the division conducted ambient biological, water column chemical and sediment sampling, as well as fish sampling. This was all part of the five year basin approach for monitoring and assessment under the National Pollution Discharge Elimination System (NPDES) permit and to facilitate a Total Maximum Daily Load (TMDL) for the watershed.
