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.

H2Ohio Agency Story Maps

H2Ohio is highly collaborative, including work from ODA, ODNR and Ohio EPA to achieve improved water quality. Wetland projects and water infrastructure projects are being constructed and completed statewide. Agricultural best management practices are being implemented on farmland across the Western Lake Erie Basin. A comprehensive look at H2Ohio efforts across the state can be viewed in one place here on the H2Ohio Story Map.

“I wanted to be involved in H2Ohio. I mean, we participated in conservation practices through the Soil and Water in the past, it was a good fit for us. We’re always trying to learn to do something a little better.”

Denny Vennekotter

H2Ohio Producer

“Governor Mike Dewine, ODNR Director Mary Mertz, and the State Legislature should be commended for their efforts to improve the quality of water for all Ohio residents by investing not only in the creation of a large number of wetlands which can substantively reduce the primary cause of Harmful Algal Blooms, but also for their wisdom to include funding to evaluate the effectiveness of each of the wetlands.”

Dr. W. Robert Midden

“While we know H2Ohio practices work at a field scale, support from Ohio Lake Erie Commission  and HABRI for watershed modeling efforts is critical to determine impacts at larger scales, and the amount of practices needed to reach Lake Erie water quality targets.”

“It’s something that’s hard to relate to if you already have a public water utility. The ones that don’t have a public utility will buy a big flatbed truck or similar truck, put a 500-gallon tank in the back, drive down to the county seat in Caldwell, fill it up however many times a week or a month that they need to, and then they come and dump that tank into a holding tank at their house. Constantly budgeting showers and laundry, and that kind of thing, you know, it’s hard to put a price tag on. It’s life changing when someone goes from we don’t have water to thank you for the water.”
