class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Per- and polyfluoroalkyl substances (PFAS) represent a class of synthetic chemicals that have become one of the most significant environmental contamination challenges of the 21st century. Used extensively in industrial applications since the 1950s, these compounds resist degradation, accumulate in the environment, and pose documented health risks at extremely low concentrations.<\/p>\n<p>The detection of PFAS contamination in drinking water supplies, groundwater, and surface waters has accelerated regulatory action across federal, state, and local jurisdictions. Industries that generate, handle, or discharge water must understand PFAS contamination risks and implement monitoring programs that demonstrate compliance while protecting public health.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_PFAS_Compounds\"><\/span>What Are PFAS Compounds?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Chemical_Characteristics\"><\/span>Chemical Characteristics<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>PFAS compounds share a unique chemical structure featuring a <strong>fluorinated carbon chain<\/strong> attached to various functional groups.
