For nearly eight decades, Los Alamos National Laboratory has contaminated waters and soils with myriad hazardous chemicals and radioactive waste. Now, testing by scientists around the mesa-top nuclear weapons lab reveals widespread—and in some instances, extremely high—levels of PFAS, or per- and polyfluoroalkyl substances.
Most of the samples they collected revealed just traces of various members of the PFAS family, including perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). But some water samples ranged from 4,130 parts per trillion to 4,290,000 parts per trillion. Read more…
