They all contain carbon-fluorine bonds, which are one of the strongest chemical bonds in organic chemistry. They are also not easily degradable and remain in the environment, thus widely considered as \u201cforever chemicals\u201d. PFAS accumulate in animal and human tissue and are toxic at low levels of bioaccumulation, can cause problems to the endocrine nervous system and several other health problems.<\/p>\n<p>Clean, safe drinking water is fundamental to life, communities, and people. The US EPA (Environmental Protection Agency) has taken an extraordinary step, a first in 26 years, proposing legal drinking water limits for contaminants in drinking water.\u00a0Municipal utilities will be required to remove six of the most studied and toxic PFAS compounds from drinking water.<\/p>\n<p><strong>National Primary Drinking Water Regulation (NPDWR)<\/strong><\/p>\n<p>EPA expects that in years the final rule will prevent PFAS exposure in drinking water for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious PFAS-attributable illnesses.<\/p>\n<p>The new EPA regulations set Maximum Contaminant Levels (MCLs) for PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid) at 4 parts per trillion (ppt); PFNA (perfluorononanoic acid), PFHxS (perfluorohexanesulfonic acid), and GenX (hexafluoroproplene oxide) at 10 ppt; and a hazard index for mixtures of PFNA, PFHxS, GenX and PFBS.<\/p>\n<p>Water Systems in the US are required to start testing for these six compounds within three years, report the results in the annual Water Quality Report, and notify customers of any violations.\u00a0 Systems have five years to comply with the new MCLs by either installing appropriate treatment or finding alternative PFAS-free water supplies.<\/p>\n<p>To successfully adhere to the new PFAS regulations, EPA has identified the following as best-of-breed technologies:<\/p>\n<ul>\n<li>Granular activated carbon (GAC)<\/li>\n<li>Anion Exchange (AIX)<\/li>\n<li>Nanofiltration (NF)<\/li>\n<li>Reverse Osmosis (RO)<\/li>\n<\/ul>\n<h2><\/h2>\n<p>&nbsp;<\/p>\n<h2><strong>PFAS Regulations in Europe <\/strong><\/h2>\n<p>In Europe, PFOS &amp; PFOA were phased out and are now restricted under the EU POP (Persistent Organic Pollutants) regulations making manufacture, import and export largely prohibited. In late 2020 the EU Quality of Water Directive was amended to minimize PFOS &amp; PFOA levels in drinking water. According to the directive, each member state must enforce the regulation by 2026.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/ide-tech.com\/wp-content\/uploads\/2023\/01\/light-blue-wave.svg\" \/><\/p>\n<h2>PFAS Removal Technologies<\/h2>\n<p>PFAS are found in rivers, lakes, and reservoirs all over the world.
