In a recent PFAS fireside chat, Dr. John Washington from the US EPA discussed the findings of a recent study published in Science that detected a novel group of per- and polyfluoroalkyl substances (PFAS)—called chloroperfluoropolyether carboxylates (ClPFPECAs)—in soil...
With the risk of per- and polyfluoroalkyl substances (PFAS) contamination and accumulation in humans and wildlife on the rise, it is important to continuously improve and demonstrate capabilities for accurate and precise low-level quantification in research and...
US Environmental Protection Agency (EPA) and Department of Defense (DoD) methods for testing per- and polyfluoroalkyl substances (PFAS) in drinking water require using solid phase extraction (SPE). SPE has been used extensively in environmental contaminant analysis...
Read time: 2 minutes Short-chain per- and polyfluoroalkyl substances (PFAS) are increasing in the Canadian Arctic environment, with the most rapid increases occurring post-2000, according to a recent study in Geophysical Research Letters (April 2020). For example,...
Read time: 2 minutes According to a recent study from Harvard University, the US EPA, and NIEHS, traditional targeted analysis techniques poorly characterize the PFAS composition of contemporary PFAS-based firefighting foams, know as aqueous film-forming foams...
