Polyfluorinated Alkyl Substances (PFAS) are ubiquitous man-made chemicals that are extremely stable under environmental conditions. PFAS have many uses, including in industrial polymers, stain repellants in textiles, aqueous film forming foams (AFFF) for fire suppression, and food packaging. Due to their prevalence, PFAS impacted sites could range from water sources near airports to groundwater wells near municipal solid waste landfills. The most well-known of the PFAS are perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). PFAS are persistent in the environment and tend to bioaccumulate in the food chain.
The U.S.EPA and the California State Water Resources Control Board (Water Board) have both established risk-based notification limits for PFOS and PFOA: 70 ng/L for both from the U.S.EPA, and 13 and 14 ng/L respectively from the CA Water Board. The CA Water Board has issued investigative orders for PFAS monitoring in groundwater wells that either had previous PFAS detections, or are close to airports or municipal solid waste landfills-with the potential of selecting over 1,000 wells.
Weck Laboratories has gained CA ELAP certification to perform EPA method 537.1, the most complete certifiable drinking water method available with 18 target compounds. We have been performing PFAS testing for over 10 years, and our advanced analytical services group has seven triple-quadrupole mass spectrometers, with a combined several decades of experience. Additionally, we have the capability of analyzing 14 additional targets, for a total of 32 PFAS compounds.
