Ohio River http://wfpl.org en Biologists Use New "Bug Index" to Evaluate Ohio River Water Quality http://wfpl.org/post/biologists-use-new-bug-index-evaluate-ohio-river-water-quality <p>For years, biologists have analyzed fish tissue to gauge the water quality in rivers. But in the Ohio River, researchers are now looking at bugs, too.</p><p>Ryan Argo and Jamie Wisenall are standing in the shallows of the Ohio River, just outside Owensboro.
