Monitoring PFAS in water sources
Non-targeted adsorbable organically bound fluorine (AOF) analysis by CIC Per- and polyfluorinated alkyl substances (PFASs) are thousands of organic molecules in which all the hydrogen atoms on at least one carbon are replaced by fluorine [1]. PFASs are widely used in different industries, e.g., as surfactants for film-forming foams or as impregnating agents for packaging [2]. Due to ...

Adsorbable organic fluorine (AOF) – a sum parameter for non-targeted screening of per- and polyfluorinated alkyl substances (PFASs) in waters
The prevalence of per- and polyfluorinated alkyl substances (PFASs) and other perfluorinated compounds (PFCs) that persist and accumulate in the environment (as well as in our own bodies) is becoming an increasing concern to international health authorities. These chemicals are a class of stable compounds known as «forever chemicals» and are comprised of nearly 10,000 different ...

Guidance on PFAS Remediation
As of June 15, the EPA released new guidance about PFAS, with four drinking water health advisories as well as the first $1 billion round of grant funding “to address PFAS and other emerging contaminants in drinking water.” In addition to these new guidelines, the EPA will propose new PFAS regulations this fall. PFAS, or per- and polyfluoroalkyl substances, are a group of ...

Changing Biosolid Technology to Safely Remove PFAS Chemicals
Per and Polyfluoroalkyl substances (PFAS) are ubiquitous. Known as “forever chemicals,” the man-made carbon-fluorine bond is one of the strongest bonds found in nature. PFAS is fast to build up in humans, animals and the environment and very difficult to break down. These substances were developed in the 1940s and 50s and applied to products that range from cookware to dental ...
