Draft State of Per-and Polyfluoroalkyl (PFAS) and Risk Management Scope for Per- and polyfluoroalkyl substances by ECCC and HC – Supporting

The State of the PFAS report and the Risk Management Scope document were released for public comments during a time when Bill S-5 (Strengthening Environmental Protection for a Healthier Canada Act) received Royal Assent on June 13, 2023. The updated CEPA includes substantial changes to the listing of toxic substances under Schedule 1 of CEPA. The findings of the State of PFAS concluding PFAS as a class meet more than one criterion under section 64 are expected to be relevant due to the changes in CEPA. A listing of PFAS as a class under CEPA should be made in Part 1 of Schedule 1 of CEPA. Based on the body of evidence collected in the State of the PFAS report demonstrating the ecological toxicity and associated impacts of PFAS as a class to health, it is critical that PFAS as a class be given the full scope of regulatory measures, particularly with a focus on prohibition, that is permitted under CEPA.

Per- and polyfluoroalkyl substances under Annex 3 of the Great Lakes Water Quality Agreement – Joint

On behalf of the 23 undersigned organizations, we are writing concerning work on per- and polyfluoroalkyl substances (PFAS) under Annex 3 of the Great Lakes Water Quality Agreement. We urge the U.S. and Canadian Governments to work together in developing a joint binational strategy to address these chemicals in the Great Lakes region.

As you know, under Annex 3 of the Great Lakes Water Quality Agreement (GLWQA), the Canadian and U.S. Governments (the Parties) have designated two individual PFAS and their isomers (perfluorooctanoic acid, or PFOA, and perfluorooctane sulfonic acid, or PFOS) and one category (long-chain perfluoroalkyl carboxylic acids, or LC-PFCAs) as chemicals of mutual concern (CMCs).

Time to clean the swimming pool but where to drain the water?

MEDIA RELEASE:  For Immediate Release – 14 May 2020

Time to clean the swimming pool but where to drain the water?

It’s that time of year when you are likely thinking about getting the pool or hot tub ready for the summer season.  It’s a good idea to prepare by first checking with your local town or city to find out what you should do with the water when you drain the pool.  “Beware, that releasing pool or hot tub water containing chlorine or salt directly into the street or a storm drain could bring a very heavy fineThat’s because those chemicals would then flow untreated into a local stream, river or lake and could result in a fish die-off or be very harmful to aquatic life”, said Linda Heron, Chair of the Ontario Rivers Alliance (ORA).

NGO Comments on Draft Binational Screening Criteria for Nominated Chemicals of Mutual Concern – ORA Support

The government recommendation asks whether the current concentrations of the chemical “exceed” the benchmarks or guidelines. This implies that we are okay until the benchmarks or guidelines are exceeded. This is not true. Health impacts don’t suddenly start to occur when you cross that narrow threshold of meeting the threshold and move into exceeding. We are already in trouble once we are near or have met the benchmarks or guidelines.
