Meta AI Data Center Linked To Rare Bacteria In City’s Water System

A rare bacteria has been found in a Wyoming city's water supply, and local health officials have traced the contamination to wastewater from a Meta AI data center that is still under construction. The discovery has sparked urgent public health concerns and raised questions about the environmental oversight of Big Tech's massive data center buildouts.

The bacteria, identified as *Mycobacterium chimera*—a pathogen that can cause severe lung infections in immunocompromised individuals—was detected during routine water quality monitoring in the city's municipal system. Investigators from the Wyoming Department of Environmental Quality traced the bacteria's source to sediment-laced wastewater discharged from the construction site of Meta's next-generation AI data center, located just outside city limits. The facility, part of Meta's multi-billion-dollar push to expand its AI computing infrastructure, is being built to house thousands of high-performance GPUs that require immense amounts of water for cooling.

Data centers have long been scrutinized for their water consumption, but this is one of the first documented cases where construction runoff from such a facility has introduced a pathogenic microorganism into a public water supply. *Mycobacterium chimera* is notoriously difficult to eliminate because it forms biofilms and is resistant to standard chlorine disinfection. Health officials have issued a boil-water advisory for affected neighborhoods and are distributing bottled water to vulnerable residents, including those in hospitals and nursing homes.

Meta has stated it is cooperating fully with the investigation and has halted all construction water discharge pending a full review. 'We take this matter extremely seriously and are working to understand how our site could have contributed to this situation,' a Meta spokesperson said. The company has also offered to fund additional water testing and filtration improvements for the city. However, local residents have expressed anger and frustration, with some questioning whether Meta should have conducted more thorough environmental impact assessments before beginning construction.

The incident comes amid a broader debate about the environmental costs of AI infrastructure. According to estimates from the Electric Power Research Institute, data centers could consume up to 9% of total U.S. electricity generation by 2030, with water usage similarly skyrocketing. While large technology companies have pledged to be 'water positive' by 2030, this case illustrates that even construction-phase impacts can have serious consequences. Environmental engineers note that excavation and concrete work often disturb soil containing dormant bacteria, which can then be washed into waterways if proper sediment controls are not in place.

Looking ahead, the city is expected to lift the boil-water advisory once testing confirms the bacteria has been flushed from the system, a process that could take several weeks. Meta faces potential fines and lawsuits, and the incident may prompt state and federal regulators to tighten construction runoff rules for industrial-scale data centers. For the broader AI industry, this is a stark reminder that the race to build ever-larger models has physical-world consequences that extend far beyond carbon emissions.
