The Guardian- About 20m acres of cropland in the United States may be contaminated from PFAS-tainted sewage sludge that has been used as fertilizer, a new report estimates.
PFAS, or per- and polyfluoroalkyl substances, are a class of about 9,000 compounds used to make products heat-, water- or stain-resistant. Known as “forever chemicals” because they don’t naturally break down, they have been linked to cancer, thyroid disruption, liver problems, birth defects, immunosuppression and more.
Dozens of industries use PFAS in thousands of consumer products, and often discharge the chemicals into the nation’s sewer system.
