Is there any reason the water can’t be safely consumed later? It’s not toxic or nuclear is it? The cooling water didn’t just up and disappear did it?

Edit addendum: I’d like to thank everyone that’s participated in this question thread, sorry if I missed any good relevant links in the comments.
To be clear, I still loathe the whole AI datacenter era, it really is heavily wasteful of resources, notably energy, but I wanted to better understand the water usage situation.


There will undoubtedly be some level of contamination.
No more than any normal level of evaporated water in the area. Its literally just water evaporating from heat.
