Indeed. I apologize.
PFAS, or perfluorinated compounds, are a broad class of chemicals—upwards of 5,000 chemicals—used in a variety of applications, including in aqueous film-forming foams. They have been found through contamination events in drinking water supplies, thereby finding their way into some drinking water. From a broad perspective, between 2006 and 2015, Health Canada, in collaboration with Environment and Climate Change Canada, has taken action under the Canadian Environmental Protection Act to prohibit many subclasses of that broad class of substances. More recently, it published a report on the state of the PFAS, a comprehensive review of the science of those 5,000 chemicals in which it was proposed that there were risks to both health and the environment.
