Levels of one ‘forever chemical’ are increasing in groundwater, study finds

Credit: Unsplash/CC0 Public Domain Rain and water in ponds and lakes slowly seeps into the soil, moving through minute cracks to refill underground aquifers. Per- and polyfluoroalkyl substances (PFAS), often described as forever chemicals, can tag along into groundwater that’s later removed for drinking. Researchers analyzed water from over 100 wells in Denmark for one … Read more
