PFAS\u2014those &ldquo;forever chemicals&rdquo; you&rsquo;ve been hearing about\u2014wasn&rsquo;t on the engineering checklist. And that&rsquo;s exactly why they&rsquo;re contaminating drinking water supplies across the country.<\/p>\n<h2 id=\"what-are-pfas-and-why-should-you-care\"><span class=\"ez-toc-section\" id=\"What_Are_PFAS_and_Why_Should_You_Care\"><\/span>What Are PFAS and Why Should You Care?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>PFAS (per- and polyfluoroalkyl substances) are a family of over <strong>12,000 synthetic compounds<\/strong> used in everything from non-stick cookware to firefighting foam. Their carbon-fluorine bonds\u2014the strongest in organic chemistry\u2014make them virtually indestructible. Once they enter your body or your water supply, they stay forever.<\/p>\n<p><strong>The contamination scale is staggering:<\/strong><br \/>\n&#8211; <strong>2,800+<\/strong> military installations affected by PFAS from firefighting foam<br \/>\n&#8211; <strong>400+<\/strong> major airports with PFAS-contaminated groundwater<br \/>\n&#8211; <strong>200 million<\/strong> Americans drink water containing detectable PFAS levels<\/p>\n<p><strong>Health impacts<\/strong> include cancer, thyroid disease, fertility problems, and immune system disruption.

PFAS are dissolved compounds\u2014they don&rsquo;t coagulate.<\/p>\n<p><strong>Sand filtration<\/strong>: Filter pores measured in fractions of a millimeter can&rsquo;t capture molecules. PFAS molecules are <strong>nanometers<\/strong> in size\u2014thousands of times smaller.<\/p>\n<p><strong>Chlorination<\/strong>: Chlorine kills bacteria and oxidizes iron and manganese. PFAS resist all oxidation. You could chlorinate PFAS-contaminated water indefinitely with zero destruction.<\/p>\n<p><strong>Biological treatment<\/strong>: Activated sludge removes organic matter through microbial metabolism. PFAS are chemically inert\u2014microorganisms can&rsquo;t metabolize them.<\/p>\n<p><strong>The uncomfortable truth<\/strong>: Your drinking water treatment plant has no technology onboard to remove PFAS.
