Rare Bacteria Contamination Sparks Scrutiny Over Meta's Wyoming Data Center Project

A rare bacterium discovered in a major US city's wastewater system has raised concerns about the construction of Mark Zuckerberg's new data center project. Meta's massive artificial intelligence facility in Wyoming faces intense scrutiny following an unexpected contamination incident that occurred during its development phase. The tech giant is building a sprawling 715,000-square-foot campus in Cheyenne with plans to launch operations next year. However, the company's contractor has come under fire after local officials traced hazardous wastewater containing a specific microorganism directly to the construction site.

This naturally occurring bacterium, scientifically known as Cupriavidus gilardii, usually resides harmlessly in soil and water sources around the world. While it poses little threat to healthy individuals, medical experts warn that it can trigger severe pneumonia, bloodstream infections, and lung issues for people with compromised immune systems. In extremely rare instances, exposure to this pathogen has even led to death among vulnerable populations who lack strong natural defenses against such pathogens.

Cheyenne's Board of Public Utilities identified Goat Systems as the source of the problem after analyzing wastewater discharged from the construction zone. The utility board stated that they first detected the bacteria during routine sampling in late February, though public announcement did not occur until last Thursday. Meta claims its general contractor, Fortis, immediately began removing industrial wastewater off-site to prevent further spread. Independent testing conducted since then has reportedly found no remaining traces of the substance within the affected areas.

City officials emphasized that the contamination never reached the municipal drinking water supply used by residents for daily consumption. Despite this safety assurance, the incident significantly disrupted the city's reclaimed water recycling system and necessitated extensive cleanup efforts lasting several months. As a direct consequence of these findings, Cheyenne has permanently revoked Meta's authorization to discharge wastewater from fill-and-flush operations into its treatment infrastructure. This facility recycles treated water for irrigating local parks and other public green spaces throughout the region.

The planned 715,000-square-foot campus remains scheduled to come online next year despite these regulatory setbacks. Community leaders are now reflecting on the potential long-term risks such industrial projects pose to local environmental health standards. The situation highlights the complex challenges of balancing rapid technological expansion with rigorous safety protocols for public water systems.

A contractor for Meta's new data center project has faced intense criticism after wastewater containing a rare bacterium was linked to the facility. A representative for Meta explained to the Daily Mail that when local authorities detected a substance in the city's reclaimed water supply, Fortis—the construction company responsible—immediately halted all discharges and began removing the fluid from the site.

The tech giant stated that its team engaged an independent environmental expert to conduct fresh tests, which found no traces of the contaminant. Meta emphasized its dedication to acting as a responsible neighbor in Cheyenne and pledged to support ongoing cooperation between Fortis and city officials until the issue is fully resolved. This incident arrives as artificial intelligence data centers across the United States face increasing pressure regarding their heavy consumption of local water and electricity resources.

Data Center Map indicates that nearly 4,500 such facilities operate nationwide, with some individual sites drawing up to 300,000 gallons of water daily—a volume comparable to the usage of 1,000 households. Goat Systems LLC serves as the entity Meta utilizes for building the site, known as Project Cosmo. City officials clarified that the contaminated fluid was released during a standard fill-and-flush procedure intended to prime the cooling system before operations begin.

While authorities confirmed the city's drinking water supply remained untouched, they noted that the municipal reclaimed water system was disrupted, necessitating months of remediation work. The process described involves filling piping with water, flushing out debris, and then directing the used liquid into sewer lines. Although officials identified *Cupriavidus gilardii* in the wastewater, they have not yet determined the specific origin of the bacterium.

The water utilized for this procedure was purchased from Cheyenne's Board of Public Utilities. Despite the discovery occurring earlier in the year, investigators required several months to pinpoint the source of the contamination before announcing their findings last week. The news that Meta's data center was responsible caught local leaders off guard; City Councilman Pete Laybourn described the revelation as "a very, very unpleasant surprise."

Laybourn expressed prior concerns regarding certain agreements struck between the city and the project operators in an interview with Cowboy State Daily. He remarked that while such problems are a reality they must address, they represent the least desirable outcome possible for the community at this time. The Mark Zuckerberg-owned corporation reiterated its commitment to being a good neighbor in Cheyenne.

Medical literature highlights the potential severity of the organism involved. A study published in March 2026 within the International Journal of Infectious Diseases documented 32 human cases of *Cupriavidus* infection globally, noting that ten patients succumbed to severe complications. Researchers pointed out that almost all fatalities involved individuals with pre-existing medical conditions or compromised immune systems. One of the earliest recorded deaths occurred in 2010 involving a 12-year-old American girl who died from sepsis after contracting the bacteria during a family vacation in Europe, according to a report from the National Library of Medicine.
