They are used in products like fabric stain protectors and waterproofers, food packaging, lubricants, and firefighting foams. But PFASs are probably most well-known for their use in Teflon to keep food\u00a0from sticking to cookware.<\/p>\n<p class=\"graf--h3 graf--leading graf--title\">&#8220;Drinking water contamination with poly- and perfluoroalkyl substances poses risks to the developmental, immune, metabolic, and endocrine health of consumers,&#8221; the study abstract states. &#8220;We find drinking water supplies for 6 million U.S. residents exceed US EPA\u2019s lifetime health advisory (70 ng\/L) for PFOS and PFOA.&#8221;<\/p>\n<p class=\"graf--h3 graf--leading graf--title\">Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are\u00a0substances that come from PFAS.\u00a0<a href=\"https:\/\/thinkprogress.org\/millions-of-americans-may-be-drinking-toxic-water-harvard-study-finds-5778082bf7aa#.260iu3voq\" target=\"_blank\">This <em>Think Progress<\/em> article<\/a> (which provides a good summary of the research) noted these significant study findings:<\/p>\n<ul>\n<li class=\"graf--h3 graf--leading graf--title\">Being near a manufacturing site makes a public water system 81% more likely to have elevated levels of PFAS pollution.<\/li>\n<li class=\"graf--h3 graf--leading graf--title\">75% of public water systems that exceeded PFAS federally recommended safety levels were found in 13 states: Alabama, Arizona, California, Florida, Georgia, Illinois, Minnesota, Massachusetts, New Jersey, North Carolina, New York, Ohio, and Pennsylvania.<\/li>\n<\/ul>\n<p class=\"graf--h3 graf--leading graf--title\"><a href=\"https:\/\/www.wqa.org\/programs-services\/resources\/news-releases\/id\/96\/wqa-responds-to-new-harvard-study-on-pfoa-and-pfos\" target=\"_blank\">In this issued response to the study<\/a>, Water Quality Association (WQA) Deputy Executive Director Pauli Undesser said: \u201cThis study emphasizes human exposure to unregulated substances with health risks. It is important for consumers to know that public water systems are not required to test and monitor for PFOA and PFOS.&#8221;<\/p>\n<p class=\"graf--h3 graf--leading graf--title\">While public water systems are not required\u00a0by the EPA to monitor or test for these substances at this time, that could change in the future.<\/p>\n<p class=\"graf--h3 graf--leading graf--title\">The Think Progress articles states that, &#8220;In May, the EPA lowered the recommended safety levels of PFOA and PFOS \u200ato no more than 70 parts per trillion.&#8221; The article also notes that, historically, lowering safety levels suggests\u00a0additional EPA regulations could be coming in the next few years.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Research reveals millions of Americans may
