MARA’s Bitcoin Mining Became a Nightmare for this Texas Town

A 4-year-long dispute between residents of rural Hood County and a nearby Bitcoin mining operation has exposed the social costs of Texas’ crypto boom. Homeowners turned against one of the state’s largest digital-asset miners.

At the center of the conflict is a large Bitcoin mine operated by MARA Holdings near Granbury in unincorporated Hood County.

Bitcoin Mining Becomes a Constant Mental Torture

Neighbors say a constant, low-frequency hum from the facility’s cooling systems has turned daily life into what they describe as a never-ending ordeal. MARA (formerly Marathon Digital) says it operates legally, brings investment and jobs, and has taken steps to reduce noise.

The mine began operating in 2022 next to a natural-gas power plant outside Granbury. Residents soon reported round-the-clock noise, likening it to “standing on a runway” or “the edge of Niagara Falls.” Complaints intensified through 2023 as the site expanded.

A Resident’s Comment on the Hood County Bitcoin Mining Situation

“This is a sound that blasts me every day when I walk out of my back door,” one resident said in a recent Al Jazeera report. Others described sleepless nights, headaches, and stress. “The community is sick,” another resident said. “More than just noise, it’s a physical bombardment. It’s torturous.”

Texas Crypto Boom Meets Local Limits

Texas has become the largest Bitcoin mining hub in the United States, hosting close to 30% of national mining power by 2023, drawn by cheap land, low taxes, and a deregulated power market.

That growth has collided with a key legal reality. Counties in Texas generally cannot pass enforceable noise ordinances. Only cities can.

Hood County officials attempted to use state “unreasonable noise” statutes in 2024, issuing citations tied to high decibel thresholds.

However, the effort faltered in court, showing how narrow those laws are compared with typical municipal noise limits.

Lawsuits and Sound Studies

Residents organized and filed a private nuisance lawsuit in state court, arguing that the mine’s noise and vibration substantially interfere with their use of their homes.

The case remains active, with disputes over access to operational data and measurements.

Separately, Hood County commissioned an independent sound study in late 2024. The report documented elevated sound levels near the site and emphasized that the legal threshold used in criminal law is far more permissive than city noise standards elsewhere.

The study also noted limits in access and coordination, which prevented a full assessment under all operating conditions.

MARA says it has invested heavily to mitigate impacts. The company built a large acoustic barrier wall, replaced some cooling fans with quieter models, and began transitioning parts of the site to liquid immersion cooling.

In a statement cited by Al Jazeera, MARA said it has invested more than $320 million locally, supports dozens of jobs, generates tax revenue, and “remain[s] committed to being good neighbors.”

For residents, those steps have not gone far enough.

“This was our forever home,” one homeowner said. “I can’t sell my property. I’m being taxed at a higher rate now than my property is worth.”

A Failed Bid for Cityhood

In 2025, residents pursued a last-ditch strategy. They wanted to incorporate their community as a city, which would have allowed them to enact local noise laws.

The effort drew national attention and legal pushback from MARA, but a judge allowed the vote to proceed. Voters ultimately rejected incorporation, ending the bid to gain municipal authority.

“That was the plan,” an organizer told Al Jazeera. “But it has just fallen down because they lost that battle.”

With incorporation off the table, residents say they will continue to fight through the courts.
