    MADISON - The federal government on Wednesday released a host of
    new recommended health limits for "forever chemicals," with
    numbers drastically lower than standards Wisconsin passed this

    In its announcement, the Environmental Protection Agency invited
    states and territories to apply for the $1 billion in funding
    made available to address PFAS by the Bipartisan Infrastructure
    package passed earlier this year.

    The new interim standards are 0.004 parts per trillion for PFOA,
    0.02 parts per trillion for PFOS, 10 ppt for GenX chemicals and
    2,000 ppt for PFBS.

    PFOA and PFOS are two of the most well-researched and well-known
    compounds in the PFAS family. GenX chemicals were created
    following the phase-out of PFOS and PFOA.

    By contrast, Wisconsin is set to implement standards for
    drinking water set at 70 parts per trillion for PFOA and PFOS.
    Those limits matched the federal guidance put in place in 2016.

    The new federal recommendations for PFOA and PFOS were created
    based on human studies in populations exposed to the compounds,
    according to a news release from the agency.

    "Human studies have found associations between PFOA and/or PFOS
    exposure and effects on the immune system, the cardiovascular
    system, human development, and cancer," the release said.

    The recommendations for the other two compounds were based on
    animal studies.

    The new recommended standards aren't binding laws, meaning the
    EPA can't enforce them. The standards are meant to provide
    information to state agencies and other public health officials
    about health impacts, analytical methods and treatment
    technologies associated with PFAS contamination, according to a
    release by the agency.

    PFAS or per- and polyfluoroalkyl substances are a family of
    man-made chemicals used for their water- and stain-resistant
    qualities in products like clothing and carpet, nonstick
    cookware, packaging and firefighting foam. The family includes
    5,000 compounds, which are persistent, remaining both in the
    environment and the human body over time.

    The chemicals have been linked to types of kidney and testicular
    cancers, lower birth weights, harm to immune and reproductive
    systems, altered hormone regulation and altered thyroid
    hormones. The chemicals enter the human body largely through
    drinking water.

    The compounds have been found in a number of Wisconsin
    communities over the last several years, including Marinette,
    Peshtigo, Wausau, Eau Claire, Milwaukee, Madison and Mosinee.

    The new federal recommendations leave a wide gap with the
    state's standards for how much contamination is acceptable for
    drinking water in the state.

    Lawmakers Wednesday let the standard of 70 parts per trillion
    for drinking water stand, and the rules could go into effect as
    early as mid-July, with testing of large public water systems
    being required starting as early as November.

    But it remains to be seen if policymakers will go back to the
    drawing board to create new standards that look more like the
    federal recommendations.
