The type of PFAS remediation technology selected is often a reflection of the PFAS contamination levels and the PFAS signature (i.e. the combination of short- and long-chain PFAS substances present) in conjunction with the site-specific water chemistry and cross contaminants present in the liquid stream.
7 December 2018 The Michigan PFAS Science Advisory Panel releases Scientific Evidence and Recommendations for Managing PFAS Contamination in Michigan, which outlines evidence-based recommendations for the state as well as recommendations for areas of future research or monitoring to address gaps in information. It includes a recommendation that ...
The risks of PFAS, sometimes known as "forever chemicals," have long been known. But it's more complicated than it sounds.
Perfluorobutanesulfonic acid (PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid. [1]
PFAS tests that claim to offer results within minutes or at home should be avoided, according to Canter and Professor Mark D. Krahling, an analytical chemist at the University of Southern Indiana ...
Studies have shown that the chemicals have been linked to reproductive and developmental problems as well as cancerous tumors.
PFDA is a member of the group of polyfluoroalkyl substances (PFAS), more specific is it also a perfluoroalkyl acid (PFAA). PFAS, like PFDA, are man-made and are not naturally occurring in nature. Over the last decades they have been used in consumer products and industrial applications.
In short, the rule sets limits on several common types of PFAS. The EPA says there is enough evidence to limit PFOA and PFOS at the lowest level they can be reliably detected. For some other types, the limit is 10 parts per trillion, and there are also limits on certain PFAS combinations. Water providers will have three years to test for PFAS.
