Emerging contaminants such as Per- and Polyfluoroalkyl Substances (PFAS), and their impact on human health have quickly become a national issue. PFAS are a class of man-made chemicals used in a wide range of products including water repellent fabrics, non-stick cookware, food packaging, and fire suppression foam. Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonate (PFOS), both PFAS, have quickly gained notoriety due to their detection above the USEPA Health Advisory Level in public and private drinking water supplies across the country. Despite PFOS and PFOA having been phased out in recent years, the chemicals continue to persist in the environment. According to the Agency for Toxic Substances and Disease Registry (ATSDR), health studies have shown certain PFAS may increase cancer risks, affect the immune system, increase cholesterol levels, interfere with hormone levels, and affect pregnancy.
Our NELAP accredited laboratory uses a 537 modified method for any sample matrix: water, air, soil, tissue and sediment. Where we can, we are using isotopically labeled internal standards or isotope dilution technology to obtain the most accurate and precise results possible. Utilizing isotope dilution improves accuracy and allows low detection limit capabilities that exceed industry standard.
As the scientific and regulatory communities continue to better understand PFAS and the regulations, testing methodology, and treatment options evolve, we are committed to being on the leading edge of investigation, research and testing methodology.
