headline: Advocates raise alarm over Pfas pollution from datacenters amid AI boom
dek: 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. Big tech companies like Google, Microsoft and Amazon often need datacenters to store servers and networking equipment that process the world’s digital traffic, and the artificial intelligence boom is driving demand for more facilities. Advocates are particularly concerned over the facilities’ use of Pfas gas, or f-gas, which can be potent greenhouse gases, and may mean datacenters’ climate impact is worse than previously thought. Other f-gases turn into a type of dangerous compound that is rapidly accumulating across the globe. 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. Advocates’ concern increased in mid-September when the Environmental Protection Agency announced it would fast-track review of new Pfas and other chemicals used by datacenters. The datacenter industry has said the Pfas it uses causes minimal pollution, but advocates disagree. “We know there are Pfas in these centers and all of that has to go somewhere,” said Jonathan Kalmuss-Katz, an attorney with the Earthjustice non-profit, which is monitoring Pfas use in datacenters. “This issue has been dangerously understudied as we have been building out datacenters, and there’s not adequate information on what the long term impacts will be.” Pfas are a class of about 16,000 chemicals most frequently used to make products water-, stain- and grease-resistant. The compounds have been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease and a range of other serious health problems. They are dubbed “forever chemicals” because they do not naturally break down in the environment. Environmental advocates say the datacenters increase Pfas pollution directly and indirectly. The chemicals are needed in the centers’ operations – such as its cooling equipment – which almost certainly leads to some on-site pollution. Meanwhile, Pfas used in the equipment housed in the centers must be disposed of, which is difficult because the chemicals cannot be fully destroyed. Meanwhile, a large quantity of Pfas are used to produce the semiconductors housed in datacenters, which will increase pollution around supporting manufacturing plants. The revelations come as the US seeks an edge over China as the industry leader in AI, and there has been little political interest in reining in the centers’ pollution. “The US and China are racing to see who can destroy the environment most quickly,” said Lenny Siegel, a member of Chips Communities United, a group working with industry and administration officials to try to implement environmental safeguards. “If we had a sensible approach to these things then someone would have to present some answers before they develop and use these systems.” Two kinds of cooling systems are used to prevent the semiconductors and other electronic equipment stored in datacenters from overheating. Water cooling systems require huge volumes of water, and chemicals like nitrates, disinfectants, azoles and other
