    Intel and other semiconductor companies have joined together with industrial materials businesses to fight US clampdowns on “forever chemicals,” substances used in myriad products that are slow to break down in the environment.

    The lobbying push from chipmakers broadens the opposition to new rules and bans for the chemicals known as PFAS. The substances have been found in the blood of 97 percent of Americans, according to the US government.

    More than 30 US states this year are considering legislation to address PFAS, according to Safer States, an environmental advocacy group. Bills in California and Maine passed in 2022 and 2021, respectively.

      EPA sets limits on some “forever chemicals” as low as they can go

    On Tuesday, the Environmental Protection Agency announced that it had started the process that will see drinking water regulations place severe limits on the levels of several members of the PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemical family. PFAS are widely used but have been associated with a wide range of health issues; their chemical stability has also earned them the term "forever chemicals." The agency is currently soliciting public feedback on rules that will mean that any detectable levels of two chemicals will be too much.

    PFAS are a large group of chemicals that have uses in a wide range of products, including non-stick cooking pans, fire control foams, and waterproof clothing. They're primarily useful because of their water-repellant, hydrophobic nature. That nature also tends to keep them from taking part in chemical processes that might otherwise degrade them, so contamination problems tend to stick around long after any PFAS use. And that's bad, given that they seem to have a lot of negative effects on health—the EPA lists cancer risks, immune dysfunction, hormone signaling alterations, liver damage, and reproductive issues.

    Back in 2021, the Biden administration announced that it was starting a research and regulatory program focused on PFAS and issued preliminary guidance on acceptable levels last year. Today's announcement is the start of a formal rulemaking process that will see the development of legally binding limits. This process involves the EPA publishing proposed rules to allow the public and interested parties a chance to provide feedback. Once that feedback is addressed, formal rules will be published.
