What the source record says
Two distinct complexes: Madison County Mega Site (outside Canton) and Costas Property (west of Tougaloo College near County Line Rd, Ridgeland). Amazon's total Mississippi statewide commitment expanded to $25B including subsequent Warren County ($3B) and Hinds County ($1B) announcements. Coordinates are approximate Canton-area centroid. Veolia water partnership claim removed: About Amazon source names Arable (not Veolia) as water replenishment partner; recycled wastewater target of 83M gallons/year by 2027 is confirmed. NARROWED TO CANTON 2026-09-10 (maintainer adjudication): this record previously combined two campuses. Madison County's own tax administration treats them as separate — it 'has entered into two fee-in-lieu-of-taxes agreements with the tech giant for its data center campuses in Canton and Ridgeland' (Mississippi Free Press, 2026-08-19) — and Magnolia Tribune (2024-07-24) gives the physical split: the Madison County Mega Site is '927 acres ... located off Highway 22 and Nissan Parkway in Canton', while the Costas Property is 'an additional 786 acres in Ridgeland'. The Ridgeland campus is therefore now tracked separately as aws-costas-ridgeland-ms, and landAcres here was reduced from the combined 1,700 to Canton's 927 so the two records do not double-count acreage. ⚠️ capacityMw, investmentUsd and jobs on this record remain PROGRAM-LEVEL figures from the original Project Atlas announcement covering BOTH Madison County campuses; they are deliberately left in place here rather than split, because no source apportions them per campus. Do NOT sum them with aws-costas-ridgeland-ms, which carries no capacity, investment or jobs figures for exactly this reason. location.precision was also corrected from 'exact' to 'approximate': this record's own notes already stated the coordinate is a Canton-area centroid, so the 'exact' claim was wrong. CORRECTION: this record aggregates two campuses that Madison County's own tax/incentive administration treats as legally and financially separate -- the Madison County Mega Site (927 acres, off Highway 22 and Nissan Parkway, Canton) and the Costas Property (786 acres, Highland Colony Parkway / West County Line Road, Ridgeland) -- confirmed by a 2026-08-19 Mississippi Free Press report on Madison County's denial of AWS's Canton tax-valuation appeal: the county 'has entered into two fee-in-lieu-of-taxes agreements with the tech giant for its data center campuses in Canton and Ridgeland.' Recommend re-scoping this record to the Canton (Madison County Mega Site) campus alone -- its location.lat/lon (32.6121, -90.039) and 'exact' precision already read as Canton-specific, closer to Canton than to Ridgeland -- and using the companion new-facility record aws-costas-ridgeland-ms (786 acres, Highland Colony Pkwy/West County Line Rd intersection) for Ridgeland. Do NOT attempt to apportion this record's combined capacityMw (1000 MW planned), investmentUsd ($10B), or jobs (7,000/1,000) by site -- no source fetched in this run or last wave's states a per-site breakdown of those figures; apportioning by acreage share (54%/46%) would be a fabricated estimate. Note also that Ridgeland is itself within Madison County, so the aggregate's 'Madison County' framing is not geographically wrong, only combined.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

The row was narrowed to the Canton Mega Site (927 acres) on 2026-09-10; the Ridgeland Costas Property is tracked separately as aws-costas-ridgeland-ms.
