What is “Data Center Alley”?

A data center is a building full of computers that runs the internet — websites, cloud storage, AI. They are ordinary-looking physical buildings on real land, and they need two things in large quantities: electricity, and water for cooling.

Data Center Alley is the nickname for the area around Ashburn in Loudoun County, northern Virginia — home to one of the densest concentrations of data centers in the world. This sample is a residential neighborhood there: Brambleton, where the report below finds the nearest data center about a third of a mile away and 249 facilities inside the scan radius.

Why this matters to a landowner anywhere: when this industry clusters near land, it changes two things you can’t see from the surface — demand for nearby land, and competition for local water. The industrial water-demand scan in this report makes both visible for any parcel. Most parcels show a quiet result; this one shows what it looks like when the industry has truly moved into the neighborhood.

01What's Below

This parcel falls inside 2 federal survey zones that USGS has flagged for battery metals, semiconductor minerals, and infrastructure metals.

A survey zone is a signal worth understanding, not a guarantee of minerals — the cards below show exactly what was recorded and where.

Bedrock context · Macrostrat

diabase

Age: JurassicRock type: diabase

Diabase is a dark gray to greenish-gray igneous rock that cooled from magma below the surface. It's commonly crushed for use as road base, railroad ballast, and concrete aggregate — a common target for local quarrying where it's exposed.

Water salinity · USGS WQP

Higher chloride and dissolved-solids levels can affect taste, plumbing, and irrigation use — and these readings can shift over time as nearby withdrawal increases, whether from new wells, irrigation, or industrial and data-center demand. Above “fresh” is worth comparing against your own well or utility's test results.

Salinity readings are from nearby USGS monitoring wells and reflect aquifer conditions, not the chemistry of your specific tap or well.

⚠ Same aquifer as your parcel

Data centers can use large volumes of water directly for cooling — it depends on the facility's cooling system — and the electricity that powers them often needs cooling water too, back at the power plant. Either draw can pull from the same aquifer your well or local utility relies on.

Coverage may be incomplete — some private, unmarked, or recently-built facilities may not appear.

News-sourced records are aggregated from public reporting (citations linked per record). GeoLocity does not independently verify project status or operator claims. Coverage of announced or recently-broken-ground facilities depends on public news availability.

County industrial water use · USGS 2015

Loudoun County, VA

0.02 B gal/yr industrial (2015)

49 gal/person/year industrial per capita

USGS classification: “industrial” is SIC-code-based and primarily reflects manufacturing. Data center cooling is not explicitly categorized and may not be isolated in this figure. Most recent USGS dataset: 2015.

Future iterations may add: cooling-method classification per facility, permitted-but-not-yet-built data centers via state environmental permit databases, and per-facility water-withdrawal volumes where operators voluntarily disclose.

Most are routine regulatory registrations — not evidence of contamination

Notable: 1 federal Superfund (NPL) site — the one category worth a closer look.

In assessment / redevelopment: 2 Brownfields sites — land being assessed or redeveloped.

Routine registrations: 76 registered facilities (toxic-release reporters and hazardous-waste handlers) — common in any developed area.

To confirm conditions for a specific parcel, a Phase I Environmental Site Assessment by a licensed environmental professional is the standard tool.

Mineral-rights status defaults to 'unverified' — GeoLocity does not pull deed history. The state-default block below summarizes the state's framework for mineral-rights ownership when available. Confirm specific ownership with a licensed title professional.

Informational screening only — not legal advice. Confirm ownership with a licensed title professional before relying on any rights-status finding.
