You might already know that Cincinnati consistently ranks high on lists of cities with the cleanest, most healthy tap water in the U.S. But do you know where Cincinnati’s water comes from and how it’s sourced? If not, keep reading. We’ve got the scoop on Cincinnati’s water supply, how it’s filtered, and how it flows from the Ohio River to your home’s faucets. 

Two water plants, one big job 

First, it’s important to know that the Greater Cincinnati Water Works (GCWW) gets the city’s water from two sources. The Miller Treatment Plant, located in the California area of Cincinnati, is responsible for supplying customers with 88% of drinking water from the Ohio River. 

Additionally, the Bolton Treatment Plant has an aquifer that’s between 150 and 200 feet deep and two miles wide. Known as the Great Miami Aquifer, it contains 12 wells that treat ground water. 

How does Cincinnati keep its waters safe? 

A lot goes into making sure that the city’s water is safe for use. It starts by closely monitoring and testing the water from the Ohio River. In fact, the team at GCWW tests water even before it reaches the plants. 

The GCWW also employs an early warning organic detection system that features 13 monitoring stations along the Ohio River. The system alerts treatment plants downstream about spills so they can take measures to protect the waters once the spill reaches the area. Interesting fact: This system is the first of its type in the U.S.

Isn’t the Ohio River dirty?

On one hand, yes. In fact, the Ohio Environmental Protection Agency (OEPA) has designated the Ohio River as one of many in the country that is highly susceptible to contamination. Since it is a large body of water that is open to the environment it’s easy for pollution to gather and spread downriver. 

On the other hand, thanks to significant measures taken by the OEPA and GCWW, by the time the water gets to homes, it isn’t just safe – it’s some of the healthiest and cleanest water in the country. 

Another thing to keep in mind: the GCWW is one of only a few treatment plants in the nation that has included granular activated carbon (GAC), recognized as the best available technology for removing the common chemicals found in the Ohio River.

So, the next time you pour a glass of Cincinnati tap water, you can relax knowing that a lot went into making it incredibly safe and clean. Still concerned about your home’s water?
