Are you planning on buying or selling a property where products have been manufactured using per- and polyfluoroalkyl substances (PFAS), used a fire fighting foam or have a property where fire fighting foam has been used, or are you responsible for groundwater monitoring and sampling on a site with a release of unrelated contaminants, and have a neighbor that may have used PFAS to any significant degree?
If so, please see the timeline below:
Timeline of PFAS, PFOA and PFOS, regulations and what to expect in 2019!
PFAS (per- and polyfluoroalkyl substances) are long-chained, highly fluorinated, bioaccumulative, synthetic compounds, which are resistant to water, heat, oil, and chemicals. The combination of these unique properties makes PFAS extremely stable compounds which can be utilized in a wide range of manufacturing applications – cookware, clothes, furniture, food-packaging and retardant foam industries to name few.
With the increasing emergence of PFAS in drinking water supplies throughout the country and the discovery of the adverse health effects caused by them, the most widely known PFAS - PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid) have been on the forefront of regulatory stringency since 2016. The timeline of the critical regulatory changes with respect to the compound:
Different states have adopted their own stringent set of advisory levels for PFAS. California’s standards are summarized below:
And looking forward to 2019:
