Environmental Scrutiny of U.S. Data Centers Over Wastewater Discharges

Wastewater Contamination Triggers Regulatory Action
Officials in Cheyenne, Wyoming, discovered the bacterium *Cupriavidus gilardii* in 801,000 gallons of wastewater discharged from the under-construction Meta data center. The water, released by contractor Goat Systems, was routed to municipal sewers but not the public drinking supply. City water-resources manager Frank Strong called the finding “a big surprise” and halted the discharge pending further analysis.
In Georgia, the Flint Riverkeeper announced plans to sue QTS’s Fayetteville data center for allegedly dumping “massive amounts of dirt” and “massive concentrations of metals” into the Flint River.
Background & Context
Data centers require large volumes of water for construction, cooling and pipe cleaning. A mid-sized facility can consume about 300,000 gallons per day. After use, water is often returned to the environment under pretreatment permits, but it may contain heavy metals, PFAS and antibiotic-resistant bacteria. The Waterkeeper Alliance reports that 55 of its affiliated groups are active on datacenter water issues, with 80 % of campaigns focused on pollutant leaching.
Key Figures & Groups
- Meta – Owner of the Wyoming AI campus, $800 million, 960-acre project.
- Goat Systems – Contractor responsible for wastewater discharge at the Meta site.
- Harriet Hageman – Republican U.S. Representative from Wyoming.
- Yvonne Taylor – Vice-president of Seneca Lake Guardian.
- Chris Manganiello – Water-policy director, Chattahoochee Riverkeeper (Georgia).
- Waterkeeper Alliance – Network monitoring datacenter impacts.
Timeline
- Earlier this year – Routine water test in Cheyenne detects *C. gilardii* in Meta-related discharge.
- July 2026 – Cheyenne board of public utilities suspends wastewater intake from Goat Systems (decision under appeal).
- September 6 2026 (scheduled) – Oklahoma Corporation Commissioners will hold a special meeting to review electric service agreements for three new Google data centers.
Data & Statistics
- 801,000 gallons of wastewater contained the rare bacterium at the Meta site.
- Mid-size data centers typically use ~300,000 gallons of water per day.
- 55 Waterkeeper Alliance affiliates are engaged in datacenter water issues; 80 % of their campaigns target pollutant leaching.
Official Statements & Responses
- Harriet Hageman (letter to Meta CEO Mark Zuckerberg): “Water is a precious resource in our state, so it is of immense concern to learn the system marketed to reduce a datacenter’s water consumption caused this contamination.”
- OG&E: “OG&E is pleased to support Google and together advance growth in our home state, ensuring our current customers benefit from data center expansion that meets the technology needs of the 21st-century economy at some of the lowest rates in the country.”
Criticism & Opposition
- Yvonne Taylor warned that hot-water discharges can stress trout above 70 °F (21 °C) and fuel harmful algal blooms.
- Chris Manganiello emphasized a “void of information” about wastewater composition, urging greater transparency.
On-the-Ground Reports
Cheyenne officials expressed concern that evaporating droplets from the contaminated water could expose residents. Local activists have linked the incident to broader regional opposition to datacenter water use.
Conflicting Reports & Gaps
Meta’s claim of “no evidence” of the bacterium contrasts with the city’s test results indicating its presence. No independent third-party verification has been disclosed, leaving the true contamination level uncertain.
What’s Next
The September 6, 2026 Oklahoma Commission hearing will examine power-service agreements for Google’s upcoming facilities. In Wyoming, the appeal of the city’s wastewater suspension decision remains pending, and the Flint Riverkeeper’s lawsuit against QTS is expected to proceed through the courts.
