Louisville, KY – Results are in from a chemical study of the Ohio River. The Courier-Journal reports that among the substances found were antidepressants, veterinary hormones, and cocaine. But the researchers say the contaminants are in extremely low concentrations. The $85,000 survey was done by the eight-state Ohio River Valley Water Sanitation Commission. Samples were taken at 22 locations from Pittsburgh to Paducah. Officials say they are not sure that the levels of what they found in the river need to be reduced.
