LICKING COUNTY, Ohio - February 28th, 2026 - Ohio is rapidly becoming a hotspot for big tech investment, with major players like Meta (Facebook), Google, and Amazon Web Services (AWS) announcing plans for large-scale data centers across the state. While proponents tout the economic benefits - job creation, increased tax revenue, and technological advancement - a growing chorus of concern is rising regarding the potential environmental impact, specifically the strain these facilities will place on Ohio's vital water resources. Bernie Moreno, a prominent political figure in the state, is leading that charge, urging a cautious and comprehensive evaluation of these projects before irreversible damage is done.

Over the past year, announcements have flooded in detailing the construction of multiple data centers in Licking, Ashville, Pickaway, Hilliard, and New Albany. These aren't small operations; they are sprawling complexes designed to power the digital world, demanding enormous amounts of electricity and, crucially, water. The water isn't used for processing data directly, but for a critical cooling process. Data centers generate significant heat, and keeping servers operational requires a constant supply of water to dissipate that heat, preventing system failures.

Moreno argues that the sheer scale of water consumption by these data centers presents a significant risk to Ohio's agricultural sector and the health of its rivers and ecosystems. "We need to take a look at what the long-term impacts are," he stated recently. "We're talking about a tremendous amount of water usage. That impacts our ability to support agriculture, it impacts our ability to support our communities. You can't just trade a clean river for a data center."

The Water Challenge: Beyond Consumption

The issue isn't simply the volume of water drawn from rivers and aquifers. It's also how that water is used and returned. Data centers typically employ either a 'once-through' cooling system or a recirculating system. Once-through systems draw water, use it for cooling, and then discharge it back into the source, often at a significantly higher temperature. This thermal pollution can disrupt aquatic ecosystems, harming fish and other wildlife. Recirculating systems, while generally considered more environmentally friendly, still lose water through evaporation and require periodic 'makeup' water to compensate for losses.

Ohio already faces increasing pressure on its water resources due to climate change, agricultural demands, and population growth. Experts predict that periods of drought will become more frequent and severe, exacerbating the competition for water. Adding multiple, massive data centers into this equation significantly amplifies the risk of water shortages and ecological damage. A recent study by the Ohio Environmental Protection Agency (OEPA) - published late last year - indicated that several key river basins are already approaching sustainable water limits during peak demand periods.

Economic Benefits vs. Environmental Costs

The data center boom is undeniably bringing economic benefits to Ohio. These projects promise thousands of jobs, both during construction and in ongoing operations. They also represent substantial investments in the state's infrastructure and tax base. However, Moreno believes a purely economic calculation is shortsighted. "We can do this responsibly, but we have to make sure that we're not making decisions that hurt our long-term future for short-term gains," he emphasizes. He suggests a more nuanced approach, prioritizing sustainable development and incorporating rigorous environmental impact assessments into the approval process.

What Solutions Are Being Explored?

Several potential solutions are being discussed. These include:

• Water Use Restrictions & Regulations: Implementing stricter regulations on water usage for data centers, requiring them to adopt the most water-efficient cooling technologies.
• Water Recycling and Reuse: Incentivizing data centers to invest in advanced water recycling systems that minimize water consumption.
• Alternative Cooling Methods: Exploring alternative cooling technologies, such as air cooling or liquid immersion cooling, which reduce or eliminate the need for water.
• Sustainable Water Management Plans: Developing comprehensive water management plans that consider the cumulative impact of all water users, including data centers, agriculture, and communities.
• Renewable Energy Integration: Pairing data centers with renewable energy sources to reduce their carbon footprint and lessen overall environmental impact.

The OEPA is currently reviewing existing water permitting processes to ensure they adequately address the unique challenges posed by large-scale data centers. State legislators are also considering bills that would provide financial incentives for data centers that adopt sustainable water management practices.

The debate over Ohio's data center boom highlights a broader challenge facing communities across the country: how to balance the desire for economic growth with the need to protect our environment. Finding a solution that ensures both prosperity and sustainability will require careful planning, collaboration, and a commitment to responsible development.
