Ohio

Human Impact

The Ohio River basin is one of the most populated and industrialized regions of the United States. Oil and steel account for most of the cargoes moved on the river. The principal river ports are Cincinnati, Louisville, and Pittsburgh. Eight states (Ill., Ind., Ky., N.Y., Ohio, Pa., Va., and W.Va.) affected by the river's industrial pollution ratified (1948) the Ohio River Valley Sanitation Compact. Some results of their cleanup efforts have become discernible, and the river now supports marinas and recreational facilities.
