Data Center Protests Turn Health Concerns Into a Campaign Issue
Doug Herrera stands on the porch of the house his father built in Page, Arizona, looking out at open desert and thinking about the costs of development that may arrive next door. He has already spent years wondering whether his father’s cancer could have been tied to uranium mining pollution. Now a proposed data center has become the new object of fear, a modern industrial project with health consequences that residents say could reach far beyond noise complaints and higher power bills.
“I’m a patriot, but I’m highly against the data center,” Herrera said. The concerns are concrete and local: light pollution, sound pollution, and the possibility that higher temperatures around the facility could alter life in a small town that has long depended on its landscape and its relative quiet.
Page approved the sale of 500 acres for the proposed project, but zoning and other approvals still stand between the land deal and construction. Even before the first server rack is installed, the proposal has already become a political fault line. Petition drives, yard signs, and public opposition have turned the project into a test of how much health risk communities will tolerate in exchange for promised investment.
Air, Noise, and Heat Drive the Public Health Argument
The health debate around data centers is no longer limited to abstract concern about industrial sprawl. These facilities draw enormous amounts of electricity, and during periods of peak demand they rely on backup gas generators. That combination raises the likelihood of air pollution, especially nitrogen oxides and other emissions associated with respiratory disease, cardiovascular stress, and elevated cancer risk. Environmental studies have linked those pollutants to a range of harms, and modeling from the University of California-Riverside estimated that emissions from data centers could cause nearly 1,300 deaths annually by 2030, with a public health burden exceeding $20 billion in 2028.
The pathway is biologically plausible. Diesel and gas combustion do not remain inside the facility boundary; they disperse into surrounding neighborhoods and travel downwind. For communities already living near major highways, industrial sites, or power infrastructure, an additional source of combustion pollution can compound an existing burden. The same facilities also generate significant noise from backup generators and cooling systems, with sound levels that can exceed 90 decibels, a range associated with hearing damage after prolonged exposure.
One sentence captures the fear in places like Page: a server farm can become a neighborhood exposure source before the first shovel breaks ground.
Cooling systems add another layer of concern. Advocacy and environmental groups say some cooling components contain PFAS, the synthetic “forever chemicals” that persist in the body and the environment. Construction runoff, heavy metals, and cooling discharge can also threaten nearby water supplies and rivers. The facilities do not merely consume space; they introduce multiple exposure pathways at once, each with a different route into the body and a different set of downstream risks.
Political Backlash Is Arriving Faster Than the Projects
The growth of hyperscale data centers, built to support artificial intelligence and sprawling over tens of thousands of square feet or more, has collided with local politics in states where the facilities are being concentrated. In Arizona, the proposed Page project sits near Horseshoe Bend, one of the region’s most recognizable destinations, and opposition has spread through a community of roughly 7,000 people. Residents have spoken not only about environmental change but also about the prospect of chronic exposure to industrial noise and heat in a residential area.
The political reaction has become sharp enough to affect campaigns. In Arizona’s 1st Congressional District, candidates are split over new construction. Democratic contender Amish Shah wants a pause; Republican Jay Feely, who won his primary with an endorsement from President Donald Trump, argues that data centers are essential to keeping pace with China. The seat is competitive enough that the issue could help decide control of the House.
A similar dynamic is playing out in Ohio, where more than a dozen local referendums or initiatives related to data center construction are set to appear on ballots. Former Sen. Sherrod Brown has made the issue central to his effort to return to Congress, attacking Republican Sen. Jon Husted over tax incentives and the rapid buildout of facilities in the state. Brown’s ads accuse Husted of being “the face of data centers,” while Husted’s camp insists the companies should pay their own infrastructure costs and that siting decisions belong locally.
The numbers help explain why the issue has become so combustible. Roughly $2.5 billion in state and local tax breaks over the past decade helped bring dozens of data centers to Ohio. In rural communities, where land is cheaper and opposition can begin with a handful of organized residents, those incentives now carry a political price.
Rural Communities Are Absorbing the Burden
Data centers are moving away from urban cores and into open land, where they are harder to miss and easier to oppose. Page is one example, but it is not the only one. The siting pattern has become especially controversial in red states, where counties and townships have often welcomed large employers in the expectation of new tax revenue and jobs. The backlash has been swift enough to unsettle that calculation.
Two in 3 Americans oppose the construction of new data centers, and state-level polling in Arizona and Ohio shows strong resistance as well. In Ohio, an October survey found that 55% of adults opposed data center construction, while about two-thirds held negative views of the facilities’ environmental impact. Gallup polling found Americans more opposed to data centers in their area than to nuclear power plants. Those findings matter because they suggest the dispute is not confined to activists or environmental advocates; it has entered mainstream voter sentiment.
Alison Steele of the Environmental Health Project described the research base as early but rapidly developing. Her warning is blunt: public health evidence often arrives after the permits are signed and the concrete is poured. The pace of construction leaves little room for long observational studies before decisions are locked in.
The industry has pushed back by pointing to existing regulation and claiming that diesel backup use is minimal in established markets such as Virginia. Dan Diorio of the Data Center Coalition said companies are committed to responsible operation. Even so, the political damage is already visible in places where residents see the facilities as industrial neighbors rather than economic abstractions.
Jan Boehme, who lives near the proposed Page site, said she worries most about noise and hearing loss. Her concerns are not theoretical. They are the everyday burdens that come with living beside a facility that must stay cool, stay powered, and stay lit around the clock. In a town where the horizon has long been part of daily life, the next exposure risk may arrive with a transformer hum, a generator’s exhaust, and a wall of light that never turns off.
