Cheyenne's Board of Public Utilities traced a contamination of the city's wastewater reuse system with the bacterium Cupriavidus gilardii to Goat Systems, a company building an 800,000-square-foot data centre campus reported to be Meta's, and permanently revoked its discharge privileges. The reuse system's start for the year was delayed while the bacteria were flushed out; the city paused discharges from data centres. Meta has appealed the violation notice.
