Nearly all Americans have some type of PFAS, commonly known as “forever chemicals,” in their blood. The chemicals, which are linked to numerous health issues, were first regulated in drinking water at the federal level two years ago (though some limits have been rolled back).
But, back in 2018, New Jersey became the first state to adopt its own <a href="https://www.sciencefriday.com/segments/new-jersey-pfas-levels-drinking-water-regulations?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">drinking water standards for PFAS</a>. Now, researchers at Rutgers University have crunched the data to see how well it worked. They found that levels of the regulated chemicals dropped by as much as 55%. 
Host Ira Flatow talks with the lead author of the study, cancer epidemiologist Hari Iyer about the significance of his findings and his plans to study the possible link between PFAS and prostate cancer.
