Precise proposition checked
A planned Microsoft Mount Pleasant campus would use 8.4 billion gallons of Racine municipal water annually.
Full post context: Original claim and correction. A comment in a contemporaneous Reddit thread linking to The Guardian's Great Lakes article preserves an earlier passage saying the planned Mount Pleasant, Wisconsin, Microsoft facility was expected to use up to 8.4bn gallons of municipal water each year [C04]. The top-level post links to the article; the copied passage appears in a comment, not the post body. The Guardian's current article explicitly says its 18 December 2025 amendment changed 8.4bn to 8.4m gallons [S05]. Spectrum News 1 had already corrected a similar billion-versus-million error in its own 18 September 2025 report; it attributes the figures to data obtained from the City of Racine [S06]. Public page text was readable through web research, but the local browser showed a network-security block. The slide therefore visibly labels its image as the original publisher's correction notice, not a Reddit screenshot. C04's immutable visual capture remains incomplete.
Scope of this check: Only the earlier billion-versus-million unit scale is contradicted; the current article has been corrected.
What the evidence shows
What the corrected figure means. Spectrum reports 2.8 million gallons per year projected for 2026 and 8.4 million in the future for Microsoft's Racine County data-center development [S06]. These are municipal-demand projections, not measured current consumption. The corrected 8.4-million figure is one-thousandth of 8.4 billion. The Guardian's correction fixes its old figure; this verdict does not apply to the corrected article.
- Current article gives 8.4m and amendment note explicitly says earlier 8.4bn should have said 8.4m.
- Spectrum says City data project 2.8m gallons/year in 2026 and 8.4m in the future; its editor note corrects earlier billion units to millions.
- The Reddit comment's exact timestamp and immutable visual capture remain unconfirmed. The displayed image is the original publisher's correction notice, not a Reddit screenshot. Future municipal projections do not establish current measured consumption or facility safety.

What is true
What the corrected figure means. Spectrum reports 2.8 million gallons per year projected for 2026 and 8.4 million in the future for Microsoft's Racine County data-center development [S06]. These are municipal-demand projections, not measured current consumption. The corrected 8.4-million figure is one-thousandth of 8.4 billion. The Guardian's correction fixes its old figure; this verdict does not apply to the corrected article.
Where the claim fails
Verdict: CONTRADICTED · high confidence, bounded to the archived 8.4-billion claim. The publisher's correction and Spectrum's city-sourced report directly reject the old unit scale. Public questions about the campus's future water supply, cooling design, seasonal demand, and actual metered use remain legitimate.
Limits and uncertainty
The Reddit comment's exact timestamp and immutable visual capture remain unconfirmed. The displayed image is the original publisher's correction notice, not a Reddit screenshot. Future municipal projections do not establish current measured consumption or facility safety.
Assessment after the evidence
The original publisher corrected billion to million. This verdict concerns the earlier unit error, not the corrected article.
How the framing works
An earlier numerical unit error continues to circulate after the original publishers corrected it; this does not establish intent.
How scientists know
The publisher dated its correction, and Spectrum independently reports City of Racine projections with its own correction. The two records establish the old unit error, not actual present-day metered use.
Editorial boundaries
ACC evaluates the claim. It does not infer intent, coordination, funding, deception, or control without direct evidence specific to that attribution.
