Fakta om PFAS i dricksvatten - Norrvatten.se

Groundwater that is affected by PFOA or PFOS is often polluted by soil and air contamination. Surface water can be affected when the chemicals used in manufacturing facilities enter directly into a water source. Water supplies can also be contaminated by wastewater from washing pots, pans, utensils and fabrics made using PFOS/PFOA chemicals. 2019-01-08 · PFAS were found in the drinking water of more than 16 million Americans in 33 states [ 1 ], and a recent analysis indicates that PFAS-contaminated drinking water is much more widespread than As a result, Health Canada released guidelines for the maximum acceptable amount of PFOS and PFOA allowed in water. PFOA are acceptable in drinking water up to .0002 milligrams per liter and PFOS are acceptable at a maximum of .0006 per liter. You might assume that PFOA and PFOS would be thoroughly removed during water treatment, but in 2016, a research team found at least six million Americans were drinking water that contained a level of PFAS that exceeded the EPA’s public health recommendations in the United States.
