Another fantastic WaterFest! This year marked our 26th water festival at Miami University’s Hamilton campus. Over those years, approximately 26,000 fourth graders have explored the science of water through a day of hands-on learning and fun!

At The Conservatory today, students attending WaterFest 2026 learned about the importance of bogs for water absorption and filtration. Students also saw unique carnivorous plant species in our indoor collection and outdoor bogs.

Thank you to:
-the Ohio EPA for materials from our OEEF grant
-Our student volunteers, Henlie Krause, Jessica Anand, and Cierra Brooks, and manager, Chelsea Obrebski, for their help with this event

We want to give a shout out to all the incredible volunteers that helped with the Clean Sweep of the Great Miami River last month! It's outstanding citizens like you who keep our community beautiful, and help keep our source water clean & protected! 👏🏾

Source water protection is a shared responsibility. Protecting drinking water takes utilities, local governments, landowners, community organizations and Southwest Ohio residents working together.

This week is Source Water Protection Week. Here in Butler County, our drinking water begins at the Great Miami Buried Valley Aquifer (GMBVA). Protecting that water before it reaches the treatment plant is an important part of providing high-quality drinking water to our community.

Do you know where your drinking water comes from?

For millions of people in Southwest Ohio, the answer is right beneath our feet. The Great Miami Buried Valley Aquifer is a natural underground formation that stores and supplies fresh groundwater throughout our region.

To begin Source Water Protection Week, join Kathryn Robinson and environmental scientist Tim McLelland as they explore how aquifers work, how groundwater can become contaminated, and how monitoring and prevention help protect our drinking water.

Knowing where our water comes from is the first step toward protecting it.

Join us on September 19th for the annual Clean Sweep of the Great Miami River Watershed! 🚣‍♀
💦The Clean Sweep is an annual volunteer event focused on removing trash and restoring the health of the Great Miami River. This river cleanup is about much more than picking up trash. It’s a day for communities to demonstrate their desire for clean water and healthy rivers. It’s an opportunity to learn about our river, and it’s a time to come together with your families, your neighbors, your community, and your friends to accomplish something vital and worthy on behalf of our Great Miami River.

Two minutes. That's it.

We know everyone's busy (and attention spans aren't getting any longer 😄), so we packed some practical wise water use tips into a quick, easy-to-watch video.
