According to <a href=\"https:\/\/www.datacentermap.com\/usa\/\" data-link-name=\"in body link\">Data Center Map<\/a>, the US has almost 4,500 datacenters, some consuming up to <a href=\"https:\/\/www.npr.org\/2022\/08\/30\/1119938708\/data-centers-backbone-of-the-digital-economy-face-water-scarcity-and-climate-ris\" data-link-name=\"in body link\">300,000 gallons of water<\/a> each day, equivalent to the demands of about 1,000 households.<\/p>\n<p class=\"dcr-1s160rg\">The Cheyenne contamination was discovered in February during routine testing of wastewater discharged into public sewers from the cooling system of the datacenter campus in the High Plains Business Park, the Tribune Eagle reported.<\/p>\n<p class=\"dcr-1s160rg\">Officials identified Goat Systems LLC, a Delaware-based contractor on the 800,000 sq ft facility known as Project Cosmo, as being responsible. The city permanently revoked Meta\u2019s authority to discharge waste into Cheyenne\u2019s water treatment facilities, where it is recycled and used for irrigation in parks and other public spaces.<\/p>\n<p class=\"dcr-1s160rg\">The city also adopted a new policy prohibiting wastewater discharges from datacenters using closed loop cooling systems and fill and flush systems, which involve circulating purified water to remove construction debris, flux residue, and pipe scale, Frank Strong, BOPU\u2019s engineering and water resource division manager, told the newspaper.<\/p>\n<p class=\"dcr-1s160rg\"><em>Cupriavidus gilardii<\/em> is a naturally occurring bacterium found in soil, regarded by health experts as an \u201copportunistic pathogen\u201d harmful only to people with existing serious health conditions or weakened immune systems.<\/p>\n<p class=\"dcr-1s160rg\">A <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1201971226000780\" data-link-name=\"in body link\">March 2026<\/a> study published in the International Journal of Infectious Diseases found a patient who died of septic shock after contracting an infection from <em>Cupriavidus gilardii<\/em> during a cord blood transplantation procedure.<\/p>\n<p class=\"dcr-1s160rg\">The report said known cases of human infection were rare, with only seven reported to date. Among them was a 12-year-old American girl who died of sepsis after contracting an infection during a European vacation, according to a <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC2832434\/\" data-link-name=\"in body link\">2010 report<\/a> in the National Library of Medicine.<\/p>\n<p class=\"dcr-1s160rg\">Strong said it was not known when the bacterium entered the water, only that it was present during routine fecal bacteria testing on the discharged water.<\/p>\n<p class=\"dcr-1s160rg\">\u201cThe concern we have with our reuse system is we put it into aerosol, where we spray it onto the grass, and that increases the potential for health issues,\u201d he said. The city\u2019s irrigation program had resumed now that the datacenter\u2019s wastewater was no longer being discharged, he said.<\/p>\n<p class=\"dcr-1s160rg\">In a statement sent to the Guardian, a Meta spokesperson said the company took action immediately when it became aware of problems with Project Cosmo.<\/p>\n<p class=\"dcr-1s160rg\">\u201cWhen the board shared that it found a substance in the city\u2019s wastewater &#8211; not public drinking water &#8211; Fortis immediately stopped discharging industrial wastewater and began hauling it offsite,\u201d it said.<\/p>\n<p class=\"dcr-1s160rg\">\u201cFortis also began its own water testing with an independent environmental specialist, which has found no trace of the substance.<\/p>\n<p class=\"dcr-1s160rg\">\u201cMeta is committed to being a good neighbor in Cheyenne, including through the protection of local water resources, and will continue encouraging collaboration between Fortis and the board until this situation is resolved.\u201d<\/p>\n<p class=\"dcr-1s160rg\">Erin Lamb, BOPU\u2019s administrative and public affairs coordinator, said in an email that the city will host a press conference \u201cin the next week or so\u201d, and will not address media questions in the meantime.<\/p>\n<p class=\"dcr-1s160rg\">Public opposition to the Project Cosmo mega datacenter was already growing before the bacteria incident.<\/p>\n<p class=\"dcr-1s160rg\">The Cowboy State Daily <a href=\"https:\/\/cowboystatedaily.com\/2026\/05\/23\/opposition-and-pushback-on-data-centers-spreads-beyond-cheyenne-across-wyoming\/\" data-link-name=\"in body link\">reported in May<\/a> on pushback to projects in Cheyenne and elsewhere in Wyoming, including environmental questions about the safety and integrity of so-called closed loop cooling systems used by Meta and their tech company rivals pushing the <a href=\"https:\/\/www.theguardian.com\/technology\/artificialintelligenceai\" data-link-name=\"in body link\">artificial intelligence<\/a> revolution.<\/p>\n<p class=\"dcr-1s160rg\">The new regulations adopted by Cheyenne, Strong told the Tribune Eagle, requires companies using closed loop cooling systems to build and implement separate collection systems that direct water from cooling equipment or associated floor drains into storage tanks and offsite disposal, rather than flushing it into the city\u2019s sanitary sewer.<\/p>\n<p class=\"dcr-1s160rg\"><\/p>\n<\/div>\n<\/div>\n<div data-print-layout=\"hide\" class=\"dcr-swayiu\"><span class=\"dcr-1xhbmzr\">Explore more on these topics<\/span><\/p>\n<div class=\"dcr-2c03t5\">\n<ul class=\"dcr-p7nd18\">\n<li class=\"dcr-r721ee\"><a href=\"\/us-news\/datacenters--us-\" class=\"dcr-856iwi\">Datacenters<\/a><\/li>\n<li class=\"dcr-r721ee\"><a href=\"\/technology\/meta\" class=\"dcr-856iwi\">Meta<\/a><\/li>\n<li class=\"dcr-r721ee\"><a href=\"\/environment\/water\" class=\"dcr-856iwi\">Water<\/a><\/li>\n<li class=\"dcr-r721ee\"><a href=\"\/environment\/pollution\" class=\"dcr-856iwi\">Pollution<\/a><\/li>\n<li class=\"dcr-r721ee\"><a href=\"\/technology\/artificialintelligenceai\" class=\"dcr-856iwi\">AI (artificial intelligence)<\/a><\/li>\n<li class=\"dcr-r721ee\"><a href=\"\/us-news\/wyoming\" class=\"dcr-856iwi\">Wyoming<\/a><\/li>\n<li class=\"dcr-r721ee\"><a href=\"\/tone\/news\" class=\"dcr-856iwi\">news<\/a><\/li>\n<\/ul>\n<\/div>\n<div class=\"dcr-313bdz\"><a href=\"mailto:?subject=Wyoming%20tightens%20wastewater%20rules%20after%20Meta%20datacenter%20contractor%20flushed%20contaminated%20water&amp;body=https:\/\/www.theguardian.com\/us-news\/2026\/jul\/08\/meta-datacenter-ai-wyoming-water?CMP=share_btn_url\" class=\"dcr-ncybeu\">Share<\/a><\/p>\n<div class=\"dcr-19bkree\"><a data-link-name=\"meta-syndication-article\" href=\"https:\/\/syndication.theguardian.com\/?url=https%3A%2F%2Fwww.theguardian.com%2Fus-news%2F2026%2Fjul%2F08%2Fmeta-datacenter-ai-wyoming-water&amp;type=article&amp;internalpagecode=us-news\/2026\/jul\/08\/meta-datacenter-ai-wyoming-water\" target=\"_blank\" rel=\"noreferrer\" title=\"Reuse this content\" class=\"dcr-1c41onw\">Reuse this content<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div data-gu-name=\"right-column\" class=\"dcr-1kq7f60\"><span class=\"dcr-1ryr20k\"><\/span><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The Cheyenne board of public utilities in Wyoming.
