What they don’t mention is that the water is being polluted by the datacenters. It’s not as simple as “water go into datacenter, water come out of datacenter”

Data centers can inadvertently pollute water through chemical runoff from evaporative cooling systems, including biocides, corrosion inhibitors, and heavy metals that accumulate at scale when facilities discharge up to 5 million gallons daily.
