Texas Jury Acquits Crypto Miner Marathon of Noise Violations Following Local Residents’ Complaints

Texas Jury Acquits Crypto Miner Marathon of Noise Violations Following Local Residents' Complaints

A Texas jury has acquitted Marathon Digital’s site manager, David Fischer, of 12 noise violations linked to the company’s crypto mining operations near Granbury, Texas.

The case centered on allegations that Marathon’s mining site emitted noise levels capable of causing health issues among nearby residents.

According to a report by the Fort Worth Star-Telegram on July 10, Fischer was cleared of all charges after a six-person jury deliberated on claims that Marathon’s operations exceeded permissible noise limits.

Granbury Residents Report Adverse Health Effects


The allegations against Fischer came from complaints from over 40 Granbury residents who reported adverse health effects they attributed to the noise generated by Marathon’s mining activities.

Constable John Shirley of Hood County, who recorded noise levels exceeding 85 decibels on multiple occasions near Marathon’s site, argued that such levels could potentially lead to hearing loss over prolonged exposure, as noted by the United States National Institute on Deafness and Other Communication Disorders.

During the trial, Fischer’s defense team contested the accuracy of Constable Shirley’s measurements, arguing that they were inflated and did not accurately reflect the true impact of Marathon’s operations.

Moreover, they emphasized that any noise violations should be directed at Marathon as a corporate entity, rather than at Fischer individually.

Marathon Digital, a prominent player in the Bitcoin mining sector, utilizes specialized computers to solve complex algorithms necessary for blockchain security.

The process, known for its intensive energy consumption and heat generation, requires substantial cooling mechanisms, which some Granbury residents claimed produced a persistent, low-frequency hum associated with various health issues including heart problems, migraines, and tinnitus.

Looking forward, Marathon has committed to transitioning the majority of its air-cooled containers to immersion cooling systems by the end of the year.

The method involves submerging mining rigs in a cooling fluid to mitigate noise and thermal output, potentially addressing some concerns raised by local residents.

Marathon Digital Diversifies from Bitcoin


Last month, Marathon Digital announced its foray into mining Kaspa (KAS), a token designed to address Bitcoin’s scalability issue, as part of its diversification strategy.

Since September, Marathon Digital has mined approximately $16 million worth of Kaspa tokens, aiming to capitalize on the higher profit margins associated with Kaspa mining machines, which have reached up to 95% in some cases.

Marathon has acquired around 60 petahashes of KS3, KS5, and KS5 Pro ASICs specifically for Kaspa mining, with half of the equipment currently operational and the rest scheduled to be installed in the third quarter.

More recently, Marathon launched a 2-megawatt pilot project in the Satakunta region of Finland, which aims to warm the community using the heat generated from digital asset computing.

Bitcoin miners are seeking ways to augment their revenue following the 2024 Bitcoin halving, which reduced block rewards from 6.25 BTC to 3.125 BTC.

Marathon Digital Holdings has been actively exploring ways to monetize the excess heat generated by its Bitcoin mining facilities and data centers.
