Cheyenne suspends Meta wastewater after bacterial contamination

▪

Read, Watch or Listen

Cheyenne, Wyoming officials have linked a rare bacterial contamination in the city’s water reclamation system to construction activities at Meta Platforms’ under-construction artificial intelligence data center, known as Project Cosmo. The bacterium, Cupriavidus gilardii, was first detected during routine wastewater sampling in late February 2026 by the Cheyenne Board of Public Utilities and later confirmed by state laboratories. Although generally harmless to healthy people, it can endanger immunocompromised individuals. In response, city authorities have permanently suspended certain industrial wastewater discharge privileges for Meta, launched a multi‑month cleanup of the system, and prompted a formal congressional inquiry directed to CEO Mark Zuckerberg in July 2026.
