"Louisville is serious about its water quality!" notes an online article titled "5 Cities with the Best Water Quality."
The article was first published on Homes.com and then reprinted on a New York City news website.
"Louisville is known for a lot of great things, and its water quality is one of them," the article says. "Each day, scientists in the city perform 200 water safety tests to ensure that the tap water meets the strict Environmental Protection Agency (EPA) standards. The tap water in Louisville is sourced from the Ohio River. Treatment plants operated by Louisville Water also get water through five riverbank filtration wells. "
