She spent decades fighting over contaminated water. Now Erin Brockovich is asking a new question: where is all the water for AI going to come from?

Brockovich recently launched a crowdsourced national map that tracks AI data centers across the United States, logging facilities that are operational, under construction, or rumored. Thousands of reports have poured in from communities in nearly every state.

When those locations were laid over federal drought data, a troubling pattern showed up. A significant share of the data centers under construction right now sit in regions already struggling with drought, especially across the South and Southwest.

The timing could not be worse. More than 60 percent of the country is currently experiencing drought conditions, and water demand is climbing at the same time AI infrastructure is exploding. A single large data center can consume millions of gallons of water every day, most of it for cooling the racks of chips that never stop running.

One estimate from researchers at UC Riverside puts it in everyday terms. Generating a single 100 word AI response can use roughly one bottle of water once cooling and electricity are counted.

Residents near some of these sites are reporting the same fear over and over: that the aquifers they depend on could be drained before anyone asked their permission. Brockovich says the most common complaint is not even the water. It is transparency. Projects announced after permits are already secured, developers who never return calls, officials who signed NDAs before neighbors knew anything was being considered.

Tech companies argue newer cooling systems can cut water use dramatically, but those systems usually demand more electricity instead. Every solution trades one scarce resource for another.

Would you be okay with an AI data center being built in your town, or would you fight it?
