Summary

A routine water test at a Meta datacenter construction site in Wyoming revealed a rare and potentially hazardous bacterium in 801,000 gallons of wastewater discharged into Cheyenne's sewers. The presence of Cupriavidus gilardii was discovered in April, but officials didn't stop accepting the wastewater from the contractor until July due to concerns about potential exposure to residents through evaporating droplets. Meta disputes the validity of the city's tests and claims independent testing found no evidence of the bacterium. The incident is part of a growing national backlash against datacenters over water pollution issues, with 55 affiliated groups from the Waterkeeper Alliance working on related campaigns across the US.

Story summary

Meta's contractor, Goat Systems, was discharging wastewater from a large under-construction data center in Cheyenne, Wyoming, containing a rare and potentially hazardous bacterium called Cupriavidus gilardii. The discovery was made after officials conducted a routine test on the water, which is not meant for public drinking supply but still raised concerns that residents could be exposed to the bacteria through evaporating droplets of water used for irrigation. Cheyenne officials decided to stop taking wastewater from Goat Systems in July, but the decision is now being appealed by Meta. The data center, a $800 million AI campus covering 960 acres, is operated by Meta behind its contractor Goat Systems.

🔮 Concerned that residents could be exposed to the bacteria if they inhaled evaporating droplets of the water used for irrigation, Cheyenne officials took until July before deciding to stop taking wastewater from Meta’s contractor, Goat Systems – a decision that is now being appealed.
🔮 A new city and state government study will explore if it’s viable to capture station heat and push it deeper underground, then use this trapped heat in the winter to warm up surrounding buildings.
🔮 The Trump administration’s push to expand oil and gas extraction across the US is set to bring drilling near cherished natural and cultural sites, raising alarm among conservationists and prompting questions from the UN’s heritage body. UNESCO said it had received information on the administration’s plan to scrap a drilling-free buffer zone around the Chaco Culture National Historical Park in New Mexico, a world heritage site and one of the most important cultural areas in the US.
🔮 If all of these projects are ultimately built, the US will increase its gas fleet by around two-thirds at a capital cost of more than $647bn, Gem found.

Claims (42 extracted, 3 hedged)

When officials in Wyoming conducted a routine test on the water that was being discharged from a massive under-construction Meta datacenter, it was a shock to find it contained a rare and potentially hazardous bacterium. asserted
it → conduct → bacterium
While the wastewater flushed into sewers in Cheyenne, Wyoming, was never destined for the public drinking supply, the presence of Cupriavidus gilardii bacterium in 801,000 gallons of water ejected by a contractor for the datacenter earlier this year was still unnerving. asserted
presence → flush → datacenter
Concerned that residents could be exposed to the bacteria if they inhaled evaporating droplets of the water used for irrigation, Cheyenne officials took until July before deciding to stop taking wastewater from Meta’s contractor, Goat Systems – a decision that is now being appealed. uncertain

“It was a big surprise,” said Frank Strong, water resources manager at the city’s board of public utilities, about the discovery. asserted

Meta, which is behind the $800m, 960-acre artificial intelligence (AI) datacenter campus, said independent testing by its contractor found no evidence of the bacterium and questioned the validity of the city’s own tests. asserted

it → lade → rivers
In Virginia, authorities have brought enforcement actions against several datacenters for wastewater and wetland permit violations, in West Virginia stormwater runoff from an incomplete datacenter has twice flooded surrounding houses, all while locals and activists have campaigned against the discharge of heated water from an upcoming datacenter into Lake Seneca, in New York. asserted

liquid → use → counties
This water, released to prevent buildup of minerals and scaling in pipes, can contain heavy metals or Pfas, the “forever chemicals” that are linked to an array of health problems when ingested. asserted
that → release → problems
These Pfas can be found in the “closed loop” cooling systems that the datacenter industry lauds for using less water. asserted
industry → find → water
When used as a coolant, water can come back out hotter than when it was taken, which has alarmed critics of a controversial gas-fired facility that is pivoting from powering crypto mining to AI and draws water from Lake Seneca. asserted
