Thank you very much. I'm very pleased to have the opportunity to meet you.
I would like to talk to you about perfluoroalkylated and polyfluoroalkyl substances, or PFAS, also known as “forever chemicals”. It's a family of over 10,000 molecules that are synthesized in labs by chemists. So if PFAS are found in nature, it must be because humans intervened and put them there.
PFAS are everywhere in our day‑to‑day lives, such as in Teflon, non‑stick pans, water‑resistant sportswear, stain‑resistant treatments, Scotchgard products, firefighting foams, disposable cutlery, and so on. When paper or cardboard is water‑resistant or grease‑resistant and it looks a bit magical, it's because it contains PFASs. They are also found in a number of cosmetics. So there are a lot of them, and as a result, we are somewhat unable to do without them. There's a challenge with battery manufacturing for electric cars, though, and that may be a valid use. However, we could certainly do without them when it comes to making cosmetics or paper cups, or wrapping hamburgers.
The widespread use of PFAS has resulted in water contamination across Canada as a result of poor or virtually no industry regulation. To get an idea of the role the industry played in this large‑scale contamination, I would invite you to watch the film Dark Waters, a kind of documentary disguised as a Hollywood movie, or the other way around; I'll let you be the judge. In this case, the industry led us to believe that there were two PFAS that were harmless: perfluorooctanoic acid, or PFOA, and perfluorooctane sulfonate, or PFOS. We ended up signing a $13 billion U.S. agreement to help treat drinking water contaminated by these two PFAS alone, and that's just in the United States. There's no equivalent in Canada.
We enjoy doing research in my lab. We've collected approximately 500 samples of drinking water, or tap water, from all over Quebec, and there are only two in which we haven't been able to detect PFAS. You could say that no sample was free of PFAS, because if we improved our methods, we'd probably be able to find it in those two samples as well. I repeat that, in its normal state, water can't contain PFAS, since they are only synthetic substances.
Through this research project, we were able to identify municipalities where people were consuming water in which the concentration of these substances exceeded acceptable standards or standards that are beginning to be accepted. Is it normal that one of my students, working on a research project out of scientific interest, should have identified water pollution problems in La Baie, Val-d'Or and Sainte-Cécile-de-Milton? Depending on the case, the source of contamination may be a military base, a landfill site, an industrial site, or the use of foams containing PFAS in fire drills that were carried out improperly.
When it comes to PFAS in drinking water, Health Canada made recommendations in February 2023 that I thought were reasonable. They were a bit bolder than what had been established before, but they were still reasonable, given the difficulties and costs involved. However, a year later, those recommendations have still not been adopted. There have been comments, but we're still waiting.
Addressing PFAS and emerging contaminants of interest, such as plastics, requires better upstream control. When nothing is done, these substances end up in our rivers, lakes, drinking water, food and air. They are all over the place.
These are difficult challenges. When I try to inform the stakeholders I work with in government, I get confused, because there are too many departments, agencies and groups. Each has its own territory, prerogatives, powers and mandate. This makes it very difficult to inform people or move things forward, especially as it involves provincial, federal and municipal authorities. In all of this, I deplore the lack of communication, which makes things more difficult.
Furthermore, since these substances are everywhere, our waste water contains a lot of them. Waste water treatment plants retain a portion of PFAS in biosolids—
