Cheyenne, Wyoming, suspends wastewater acceptance from certain data center operations after city officials trace contamination to a project linked to Meta. According to reports, the city identifies a rare bacterium connected to wastewater handling connected with a building contractor working on Meta’s AI data center in the area. As a result, Cheyenne stops accepting some wastewater associated with the data center project while it investigates and addresses the issue. Inc. reports that the facility is not yet open, but enforcement actions start after the bacterial concern is detected and linked to the project. Breitbart similarly reports that the municipal wastewater treatment system experiences contamination and that the city announces a suspension of acceptance from data center operations. Both accounts frame the action as a local response to a specific biological contamination concern rather than a broader claim about the data center’s operational status. The reports do not provide further technical details about how the bacterium was introduced or the duration of the suspension.
