When you hear 500,000 gallons per day; that sounds like a big number, but its really not. Average home in US uses 300+ gal per day; so thats less than a very small town.
Everything I can find on the subject, including by companies that supply the cooling systems, says data center cooling water is treated with biocides, corrosion inhibitors, scale inhibitors, and sometimes antifreeze.What DarkBlack said. In the grand scheme of things, generally water is in a big closed recycle loop. From ground to air to rain, back to ground again. Humans tap into it for use while the big recycle loop continues to operate. We use the same water that rained on the dinosaurs.
Generally water is a pass through for a data center. It's not retained, not contaminated, nor in contact with anything other than the pipes and pumps it runs in to cool systems and processors.
It's returned as outflow, eventually back to the ground, or else vapor for those DC's using swamps or cooling towers, with evaporated water returning to the atmosphere.
