The EPA should not rescind its PFAS health guidelines. These guidelines exist to protect the health of Americans from a class of chemicals that have become one of the most widespread environmental contaminants in our nation. Weakening these protections would put countless families at greater risk. PFAS, often called "forever chemicals," persist in our bodies and the environment for years. Scientific research has linked PFAS exposure to increased risks of certain cancers, immune system suppression, developmental problems in children, thyroid disease, elevated cholesterol, and other serious health concerns. Because these chemicals accumulate over time, even low levels of exposure can be significant. For my family, this issue is deeply personal. My son has an extraordinarily high level of PFAS in his blood—reported to be among the highest documented in a child in the United States. As a parent, I have witnessed the fear and uncertainty that come with knowing your child has been exposed to chemicals that can remain in the body for years. No family should have to wonder whether the water they drink or the environment they live in has permanently affected their child's health. Rescinding or weakening the EPA's PFAS health guidelines sends the wrong message. These guidelines are not merely recommendations—they provide essential information that helps communities, water systems, health officials, and policymakers identify dangerous contamination and take action to protect public health. Removing or weakening them could delay cleanups, reduce accountability, and leave families with fewer protections against ongoing exposure. Every American deserves access to clean, safe drinking water and honest, science-based public health guidance. Children, pregnant women, veterans, and communities located near industrial facilities or military bases are especially vulnerable to PFAS contamination. They deserve stronger protections, not weaker ones. I urge the EPA to uphold and strengthen its PFAS health guidelines rather than rescind them. Public health decisions should be guided by the best available science and by the experiences of families living with the consequences of PFAS contamination. The cost of inaction will be measured not only in dollars, but in lives, health, and the trust Americans place in the institutions responsible for protecting them. With great duty Zac
