On October 18, 2024, the Canadian Food Inspection Agency (CFIA) will begin enforcing an interim standard for per- and polyfluoroalkyl substances (PFAS) in biosolids imported or sold in Canada as fertilizers.
Biosolids are the solid phase of municipal wastewater treatment, often re-used and applied to land as a source of nutrients and organic matter.
The new standard is designed to mitigate the potential risks to human health and the environment associated with land application of heavily contaminated biosolids sold as commercial fertilizer.
Enforcement of the interim standard at import and domestic levels will begin October 18, 2024. This allows four months from the publication of the CFIA’s notice for importers and domestic producers of commercial biosolids to arrange for a laboratory to perform the testing and have the certificate of analysis and attestation prepared in advance of the October enforcement start-date.
