Ohio River Multistate TMDL

The Ohio River is the largest tributary, by volume, to the Mississippi River and much of it is impaired due to high bacteria counts that affect the recreational uses of the river. The River supplies drinking water and provides recreational uses for over 5 million citizens. The Ohio River watershed covers 204,000 square miles from Pittsburgh, Pennsylvania to Cairo, Illinois, where it enters the Mississippi River. The Ohio is 981 miles long and borders Illinois, Indiana, Ohio, Kentucky, Pennsylvania, and West Virginia, and drains several more states. map of the Ohio River Watershed Bacteria Impairments

Total Maximum Daily Load (TMDL) calculations are being developed for the Ohio River to determine how much the inputs of bacteria must be reduced to return the River to health. To do this, the TMDL will examine the sources of bacteria to the River. The Ohio River receives pollutant discharges from numerous stormwater outfalls, industrial point sources, combined sewers (during heavy rains), and agricultural runoff. Water quality standards for bacteria require that all waters be protected for total body contact recreation. The U.S. Environmental Protection Agency (EPA) delegates authority to the States to regulate pollution under the Federal Clean Water Act, but because the bacteria is found in multijurisdictional locations that cross state boundaries, the EPA is providing coordination and support for the TMDL.
