Datacenters’ electricity demands have been accused of delaying the US’s transition to clean energy and requiring fossil fuel plants to stay online, while their high level of water consumption has also raised alarm. Now public health advocates fear another environmental problem could be linked to them – Pfas “forever chemical” pollution. … Advocates are particularly concerned over the facilities’ use of Pfas gas. … No testing for Pfas air or water pollution has yet been done, and companies are not required to report the volume of chemicals they use or discharge. But some environmental groups are starting to push for state legislation that would require more reporting.
