Health Canada has published a consultation technical document with the intent to provide regulatory authorities and decision-makers with an objective for per- and polyfluoroalkyl substances in Canadian drinking water supplies.
The document recommends an objective of 30 ng/L is proposed for the sum of total per- and polyfluoroalkyl substances (PFAS) detected in drinking water. For the purposes of this proposed objective, a result of non-detect is considered to have a value of zero. It is recommended that treatment plants strive to maintain PFAS concentrations in drinking water as low as reasonably achievable (ALARA).
The consultation document is available at:
Health Canada will be hosting a webinar on the consultation document in English on March 1, 2023 and in French on March 7, 2023. You can register at:

CWWA’s Drinking Water Quality Committee will be reviewing the consultation document and submitting comments if necessary. The committee also produced a fact sheet on PFAS/PFOS available from our website at https://cwwa.ca/resources/#CWWA_Reports
The committee is also reviewing draft guidelines on antimony in drinking water.
