Data Centers Are Fouling Local Water Systems in Wyoming and Georgia

Two data center water incidents surfaced within six weeks of each other in 2026, in states with nothing else in common. On July 2, 2026, Cheyenne, Wyoming’s Board of Public Utilities (BOPU) publicly identified a Meta contractor as the source of a rare bacterium that contaminated the city’s reclaimed water system for months. On May 20, 2026, Rep. Alexandria Ocasio-Cortez held up jars of brown well water at a congressional hearing, testimony tied to a Meta data center in Morgan County, Georgia that residents say has turned their tap water undrinkable. This extends WaterVerge’s coverage of data centers and water consumption from a resource-competition story into a water-quality one — the same buildout driving up demand is now showing up as documented local contamination events.

Cheyenne: A Contractor’s Wastewater Contaminates the Reuse System

BOPU staff discovered Cupriavidus gilardii — a rare, metal-resistant bacterium found naturally in soil — during a routine wastewater sample study in late February 2026. The discovery forced the city to shut down its wastewater reclamation system shortly after it came online for the season, idling the Dry Creek and Crow Creek reclamation facilities for months of cleaning.

BOPU traced the contamination to Goat Systems LLC, the corporate entity Meta uses to build its roughly 800,000-square-foot data center campus (known during development as “Project Cosmo”) in Cheyenne’s High Plains Business Park. The bacterium entered the system through wastewater generated during a fill-and-flush operation — the process of filling, testing, and draining a data center’s cooling loops before it goes live. BOPU revoked Goat Systems’ discharge privileges for fill-and-flush operations on March 24, 2026, but did not publicly name the company until July 2, after months of resident pressure over an unexplained wastewater shutdown.

Two details matter for how to read the severity of this story. First, the reuse system carries reclaimed water for irrigation and non-potable industrial use, not drinking water — this was not a tap-water contamination event. Second, testing confirmed the reclamation system was fully clean and back online by June 29, 2026. The consequence Meta now faces is structural rather than acute: BOPU has suspended acceptance of industrial wastewater from every data center’s fill-and-flush and closed-loop cooling operations citywide while it develops a permanent policy — a broader response than a single-facility penalty.

Georgia: Congress Gets Involved Over Brown Well Water

The Morgan County story runs on a different mechanism entirely. Meta’s Stanton Springs data center campus, straddling the Newton-Morgan county line east of Atlanta, now accounts for roughly 10% of the area’s total daily water use. Nearby residents — many on private wells rather than municipal service — say their water has turned brown and undrinkable since the facility began operating, with degraded water pressure damaging household appliances. Families told reporters they now rely on bottled and shipped-in water for cooking and drinking.

The dispute reached the U.S. House Energy and Commerce Committee’s Oversight and Investigations Subcommittee on May 20, 2026, when Ocasio-Cortez questioned EPA Assistant Administrator for Water Jessica Kramer while holding up two jars of murky water she said came from the affected area. Kramer directed EPA Region 4 staff to contact Georgia environmental regulators and Morgan County officials to gather more information — though EPA was careful to frame that outreach as fact-finding, not a formal federal investigation. Meta has pushed back, saying it commissioned an independent groundwater study that found no impact from its construction or operations. Separately, Mansfield Mayor Blair Northen has said local water rates are set to rise 33% over the next two years, well above the roughly 2% annual increases residents are used to — a cost local officials link to infrastructure strain from the data center’s water demand.

Two Different Mechanisms, One Common Thread

Cheyenne’s problem was a wastewater discharge failure: a contractor’s cooling-system purge carried a biological contaminant into a municipal reclamation system through a permitted but poorly monitored industrial discharge pathway. Georgia’s problem, as described by residents and officials, points toward groundwater drawdown: heavy pumping for cooling can lower the water table enough to mobilize sediment, iron, and manganese that were previously undisturbed in the aquifer, producing the discoloration and pressure loss residents describe. Meta disputes that its operations are the cause in Georgia, and the EPA’s review is still pending — the mechanism is not yet independently confirmed the way Cheyenne’s bacterial source has been.

What connects the two incidents isn’t the specific contaminant — it’s that both are downstream consequences of the same infrastructure boom. WaterVerge has covered how data center growth is reshaping regional water demand; these incidents show that demand isn’t the only risk. Industrial pretreatment programs and rural water systems were largely built around conventional industrial and agricultural users, not hyperscale cooling infrastructure that can be sited, built, and operating within a couple of years — often faster than the regulatory and monitoring frameworks around it can adapt.

Why This Matters Beyond These Two Sites

Neither incident is isolated in scale. Data center construction is concentrated in specific corridors — Wyoming’s power-and-land economics, Georgia’s Stanton Springs industrial megasite — where a single large facility can represent double-digit percentages of local water demand overnight. Cheyenne’s response, a citywide ban on data center wastewater discharges into its reuse system rather than a Meta-specific penalty, suggests utilities are treating this as a category risk, not a one-off contractor failure. Georgia’s outcome is still open: whether EPA’s fact-finding produces an actual water-quality finding, and whether Meta’s groundwater study or resident complaints prove out, will likely shape how other counties negotiate water terms with data center developers going forward.

What Residents Near Data Center Construction Should Do

If you live near a new or expanding data center, especially on a private well:

Test your well now, before and after construction begins, so you have a baseline to compare against if water quality changes later — see our well water testing guide.
Watch for turbidity, discoloration, or pressure drops and document dates; these are the same symptoms Morgan County residents reported before the congressional hearing brought attention to their case.
If you’re on municipal water, review your utility’s public notices about rate changes tied to large new industrial customers — infrastructure costs from serving a data center are often passed through to residential ratepayers.
Check your Consumer Confidence Report for any changes in iron, manganese, or turbidity levels reported by your utility — see our guide to reading the CCR.
If your water turns visibly brown or cloudy, a whole-house sediment pre-filter ahead of your regular whole-house filtration system can protect fixtures and appliances while you pursue a longer-term fix.

What Comes Next

In Cheyenne, BOPU is developing a permanent policy for data center wastewater discharges into its reuse system; other utilities serving major data center campuses will likely watch that policy closely. In Georgia, EPA Region 4’s fact-finding with state regulators is ongoing, and Meta’s independent groundwater study remains a point of dispute with affected residents. Neither case has produced a final regulatory finding as of this writing, but both have already changed how at least one utility handles industrial water users tied to data center construction.

How WaterVerge Tracks This

WaterVerge monitors SDWIS compliance data and utility service areas for cities and counties experiencing rapid industrial growth, including data center corridors. As EPA’s review in Georgia and Cheyenne’s new discharge policy develop, that information will be reflected in the affected cities’ profiles.
