Added to the tracker this week, adopted or introduced earlier. These are not this week’s activity.

• Warren County, Ohio, Six-month hyperscale data center moratorium: Pause on hyperscale data centers pending a water impact study. Adopted, Reported Sep 30, 2026. Source
• Palm Springs, California, Data center moratorium extension: Pause on data centers extended to two years. Extended, Sep 30, 2026. Source

The standing position

• 9 states have a published statewide or regional measured aggregate and draw a bar: AZ, CA, NE, NV, OH, OR, TX, VA, WY.
• 22 states have published figures at facility or instrument level only, with no state total.
• 19 states have no measured data center water volume published by anyone.

That ratio is the tracker’s central finding. The disclosure bills it follows exist because this figure is, almost everywhere, not collected.
