40 Years After First Earth Day, Ohio River is Much Cleaner »
“Biologists with the eight-state Ohio River Valley Water Sanitation Commission, which sets water quality standards for the Ohio River, say a return of a viable fishery is among the strongest evidence of improvement. Forty years ago, about all that lived in the Ohio were tough, pollution-tolerant carp and catfish, said Peter Tennant, deputy director of the commission. But surveys dating to the 1950s show steady improvement in the number and variety of fish, as well as their overall health, said Erich Emery, biological programs manager for the commission. Fish that have come back include paddlefish, smallmouth bass and logperch.”
