Key Biden-era regulations designed to protect the nations drinking water from the most dangerous cancer-causing per-and polyfluoroalkyl substances, or PFAS, were removed by the Trump administration Monday.
Manufactured since the 1940s to make products nonstick, stain-resistant and water-repellent, PFAS chemicals have been linked to cancer, obesity, thyroid disease, high cholesterol, decreased fertility, liver damage, hormone disruption and damage to the immune system, according to the US Environmental Protection Agency. Because PFAS can last for many decades in the environment, they are often referred to as forever chemicals.
Claiming the Biden administration failed to follow the law by cutting regulatory corners, the EPA will rescind and restart regulations on four PFAS, US Environmental Protection Agency EPA Administration Lee Zeldin said in a press briefing.
Those chemicals include perfluorononanoate (PFNA), perfluorohexanesulfonic acid (PFHxS) and hexafluoropropylene oxide dimer acid (HFPO-DA), the last one often referred to as a GenX chemical. All are considered dangerous to public health. In addition, the administration eliminated restrictions on mixtures of PFNA, PFHxS, GenX and a fourth chemical, perfluorohexanesulfonic acid (PFHxS). Mixtures of PFAS are even more dangerous to health, experts say.

This is the most common way of cooling in data centers, says Norbert Conrad, deputy director of the High Performance Computing Center in Stuttgart, Germany. It's similar to how a fridge is cooled, just much bigger. You use a compressor and gases to cool air or water for the computers.
These gases can escape into the air, where they accelerate climate change. Some PFAS gases used in cooling of data centers have global warming potential that is thousands of times higher than CO2's.
PFAS chemicals can also be used in a different form of cooling, using immersion. Computers are submerged in a chemical fluid to which the heat transfers. PFAS fluids for applications like this can leak or seep into water sources, where they find their way to drinking water or are used in agriculture.
