Headline: “Forever Chemicals” Found in Quebec Compost: Should you Worry About Your Garden?
Intro:
Free compost offered by municipalities in Quebec’s MRC des Sources region is raising concerns after testing revealed the presence of PFAS, the so-called “forever chemicals.” While the levels detected may fall within soon-to-be-enforced regulations, the discovery has prompted at least one town to seek alternative solutions, sparking debate about the safety and long-term impact of using this compost in our gardens.Are these freebies worth the potential risk?
The Citizen’s Discovery:
Hildegund Janzing, a resident of Ham-Sud, took matters into her own hands after noticing excessive plastic in the municipal compost. “People don’t know,which I find inconceivable,and they put this in their garden every year,” she exclaimed. Her concerns led her to collect compost samples from distribution sites in Ham-Sud, Danville, and Saint-Adrien in the spring of 2024.
Janzing sent the samples to a lab run by Sébastien Sauvé, an environmental chemistry professor at the University of Montreal. The results confirmed her suspicions: PFAS were present in every sample. These chemicals,used in countless everyday products for their water-repellent properties,are known for their potential health risks.
What are PFAS?
PFAS (per- and polyfluoroalkyl substances) are a group of man-made chemicals that don’t break down easily in the habitat or the human body. This is why they are often called “forever chemicals.” They’ve been linked to a variety of health problems, including certain cancers, immune system issues, and developmental problems in children.
The Science: Low Levels, Lingering Concerns
Professor Sauvé analyzed the test results and found that the overall concentrations of PFAS were “relatively low.” Though, he was surprised by the high proportion of PFOA and PFOS, two particularly toxic PFAS compounds that have been banned for years. He suspects these could be leaching from older, recycled products. One sample contained 3.9 micrograms per kilogram (µg/kg) of PFOA and 3.4 µg/kg of PFOS.
“When I compare it to sewage sludge across Quebec,it’s still relatively low,” Sauvé stated. “I don’t have any argument here to say that there’s something problematic. The only thing that worries me is that the [concentrations] of PFOA and PFOS are higher than what we would expect.”
Expert Advice: Caution is Key
While the levels may not be alarming, Sauvé advises caution. He recommends avoiding spreading large amounts of this compost near wells, as PFAS can migrate into groundwater. “if it’s a citizen who’s going to pick up a bin of compost to put on their lawn, there’s no problem, but I would avoid the vegetable garden as a precaution.”
The Numbers Game: Norms vs. Reality
The highest concentration of the 11 PFAS monitored by Quebec was 26.10 µg/kg, well below the province’s standard of 120 µg/kg. Though, sauvé’s lab tested for 79 different PFAS, finding a maximum concentration of 60.7 µg/kg. A proposed standard from the Bureau de normalisation du Québec suggests a limit of just 5 µg/kg for the most toxic PFAS, including PFOA and PFOS, in biosolids. This proposal is currently under review.
Industry Perspective: “Normal” to Find PFAS
Kevin Morin,Director General of the Conseil des entreprises en technologies environnementales du Québec,representing organic waste management companies,wasn’t surprised by the findings. he believes the PFAS likely originate from food packaging or materials incorrectly placed in the brown bins. Studies have shown that PFAS can migrate from containers and packaging into food.
“It’s quite normal to find a certain concentration of PFAS in compost,” Morin said.
Sauvé echoed this sentiment, explaining that cardboard, pizza boxes, and disposable cutlery treated with PFAS could end up in municipal compost.
Conflicting views on Regulations
Morin believes the new environmental standards will ensure that heavily contaminated material isn’t distributed to the public, calling them “very strict standards that the industry has been waiting for for a long time.”
Though, Sauvé considers the standards too “lax,” stating that the ministry didn’t adequately incorporate feedback from experts during the standard revision process. “So I don’t blindly trust the ministry’s threshold.”
Biogénie, one of the companies that supplied the compost, stated that their compost meets all current and upcoming standards, which they claim are “among the strictest in the world.”
What Should You do?
The discovery of PFAS in municipal compost raises critically important questions about the safety of our waste management practices and the potential impact on our health and environment. While the levels detected may be within regulatory limits, the presence of these “forever chemicals” warrants caution.
Here are some steps you can take:
Consider alternatives: Explore other composting options, such as home composting or purchasing certified organic compost.
Limit exposure: If you use municipal compost, avoid using it in vegetable gardens, especially near wells.
Stay informed: Follow developments in PFAS research and regulations.
Contact your municipality: Express your concerns and ask about their plans to address PFAS contamination.
Conclusion:
The presence of PFAS in municipal compost is a reminder that even seemingly eco-pleasant practices can have unintended consequences. By staying informed and taking precautions, we can minimize our exposure to these “forever chemicals” and protect our health and environment. The debate over acceptable levels and the source of contamination is ongoing, but one thing is clear: awareness is the first step towards finding a solution.

Headline: Exclusive Interview: Is Your Quebec Compost Safe? PFAS Expert Weighs In
Intro: Recent findings of PFAS “forever chemicals” in municipal compost in Quebec have sparked concerns among gardeners and environmental advocates alike. Time.news Editor, Sarah Miller, sat down with Dr. Evelyn Reed, a leading autonomous environmental toxicologist, to discuss teh implications of these findings, understand the risks, and learn what consumers can do to protect themselves.
Q&A:
Sarah Miller (Time.news): Dr. reed, thank you for joining us to discuss the recent news about PFAS found in Quebec municipal compost. For our readers who may not be familiar, can you briefly explain what PFAS are and why they’re raising alarm?
Dr. Evelyn Reed: Certainly, Sarah. PFAS, or per- and polyfluoroalkyl substances, are a large group of man-made chemicals used in numerous industries and consumer products for their water and stain-resistant properties. The concern stems from their persistence in the environment and the human body – hence the nickname “forever chemicals.” They don’t break down easily, and studies have linked them to a range of health issues, including certain cancers, immune system dysfunction, and developmental problems.
Sarah Miller (Time.news): The article highlights that PFAS were discovered in municipal compost in the MRC des Sources region. What does this mean for residents in that area,and more broadly,for people using municipal compost in Quebec?
Dr. Evelyn Reed: It’s a complex issue. the reported PFAS concentrations seem to fall within current regulatory limits, but the presence of these chemicals, especially legacy PFAS like PFOA and PFOS, is concerning. The key question is long-term exposure. While a single request might not pose a important threat, repeated use over years could lead to a build-up of PFAS in the soil and perhaps impact groundwater quality, particularly near wells.
sarah Miller (Time.news): The expert quoted in the article,Professor Sauvé,recommends caution and suggests avoiding using the compost in vegetable gardens,especially near wells. Do you agree with this advice?
Dr. Evelyn Reed: Absolutely.It’s always best to err on the side of caution when dealing with potentially harmful chemicals. Avoiding the use of this compost in vegetable gardens, especially those relying on well water, is a smart move. The risk of PFAS leaching into groundwater is real, and the potential for uptake by plants grown for consumption cannot be ignored.
Sarah Miller (Time.news): The article notes some conflicting views regarding existing and proposed regulations. Some believe the current standards are sufficient, while others, like Professor Sauvé, consider them “lax.” What’s your perspective on the adequacy of current PFAS regulations in Quebec concerning compost?
Dr.Evelyn Reed: Regulations are constantly evolving as we learn more about the health impacts of PFAS. It’s critical to consider the sum of available data and to lean toward protecting public health. While Quebec’s standards may align with others right now, the scientific community is increasingly advocating for stricter limits, especially for the most toxic PFAS like PFOA and PFOS. I am concerned that the views of experts weren’t incorporated.
Sarah Miller (Time.news): The source of PFAS in compost seems to be a significant point of discussion.The director of the Conseil des entreprises en technologies environnementales du Québec suggests that the PFAS likely originates from food packaging or other materials incorrectly placed in brown bins. What can be done to mitigate this source of contamination?
Dr. Evelyn Reed: Source control is essential. This means raising public awareness about what should and should not go into compost bins. Food packaging treated with PFAS, like pizza boxes and some disposable cutlery, are prime culprits. Stricter regulations on the use of PFAS in packaging would also help. Moreover, municipalities need to invest in advanced composting methods that can potentially break down or remove PFAS.
Sarah Miller (Time.news): What practical alternatives to municipal compost would you recommend for gardeners concerned about PFAS contamination, keeping in mind this article will mainly be read in Quebec?
dr. Evelyn Reed: Home composting is an excellent option, as you have complete control over what goes into your compost. Be sure to avoid adding anything that could be a source of PFAS,like coated paper products. Purchasing certified organic compost is another safe alternative. These products are typically tested for contaminants, including PFAS, and must meet stringent standards. Or even explore peat moss as a viable top soil alternative.
Sarah Miller (time.news): What are the key takeaways you want our readers to remember regarding the discovered PFAS in municipal compost?
Dr. Evelyn Reed: Be informed and proactive. Understand the potential risks associated with PFAS exposure. Take precautionary measures, such as avoiding the use of potentially contaminated compost in vegetable gardens, especially near wells. Stay informed about PFAS regulations and developments in your area. contact your local municipality with your questions and concerns so that they can provide you concrete,helpful and direct answers.
Sarah Miller (Time.news): dr. Reed, thank you for your valuable insights and advice.
Dr. Evelyn Reed: My pleasure, Sarah.
