Louisville needs to keep moving forward when it comes to new innovations in water storage and treatment. That’s according to a University of Kentucky researcher who says water is likely to become a commodity - like oil – in the future.Louisville doesn’t struggle with drought as many Kentucky cities do because it’s located on the Ohio River. But Dr. Lindell Ormsby with the Kentucky Water Resources Research Institute predicts it won’t always be that way."When we look into this century, it’s probably going to be water that becomes the big issue relative to negotiating, trying to get water, potential wars over water, water’s going to be the big issue I think in this century, where energy has been in the prevailing century," says Ormsby.Water supplies and related issues were the topic of today’s State of Affairs program on WFPL.
