A Collaborative Approach to the Issues Facing Ohio’s Water

About H2Ohio

H2Ohio is Governor Mike DeWine’s comprehensive, data-driven water quality plan to reduce harmful algal blooms, improve wastewater infrastructure, and prevent lead contamination.
“As a state, we are committed to helping farmers adopt the practices that can make a real difference. We will invest in creating more wetlands. And, we will help communities improve their water systems and remove decrepit septic systems.”
Mike DeWine

Ohio Governor

The Importance of Partnership

The Ohio Department of Natural Resources, Ohio Department of Agriculture and Ohio Environmental Protection Agency each has a significant role in H2Ohio through the creation of wetlands, the reduction in phosphorus runoff, and access to clean drinking water and quality sewer systems.

“It was an amazing opportunity to partner with ODNR, ODA, and Ohio EPA to celebrate Earth Day and inspire the next generation around H2Ohio. Together, we delivered fun, hands-on experiences to engage kids around water and nature. We are thankful for the leadership of the state to showcase how science can be fun, but also how families and youth can learn and contribute to the world around them.”

Stephen White

Esq. Chief Strategy Officer, COSI

“What continues to be impressive about H2Ohio is the willingness of stakeholders to come together to find success, not only in the program but also in the way we can support producers to manage their land more sustainably for the future. H2Ohio is giving all of us – the environmental groups, the agriculture groups, the decision makers and the landowners – the reason to try something new to make a lasting difference.”

Jessica D’Ambrosio,

“We haven’t been able to drink our water since 2019. (We) purchased bottled water to start, and then when that was starting to become too cumbersome, my husband decided to put a central line filter on our house, we were replacing the filter every week, but we’ve noticed a significant change since the temporary system has been put in.”
