Welcome to the New Resource Library
Hello! Welcome to the new and improved Drinking Water Resource Library.
If you visited here before, you will notice the format for displaying resources has changed. Instead of a catalogue, you can now search for posts on subjects that will have a collection of resources grouped together. You can choose to scroll through and browse our curated collections, or continue to search using the options down the right hand of your screen.
We hope this helps you to find what you’re looking for! If you are searching for something and would like assistance, reach out to us at dwrl@wcwc.ca.

NDMA (N-nitrosodimethylamine)
‘Levels of NDMA in Canadian drinking water are generally very low. There are no industrial or commercial uses for NDMA in Canada. NDMA can be found in both surface water and groundwater sources, but it is found in drinking water primarily from its formation during the treatment process, in particular chloramination.

‘Perfluoroalkylated substances (PFAS) are synthetic chemicals, the most common being perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). PFAS are used in a wide variety of industrial and consumer products such as adhesives, cosmetics, cleaning products, and in specialized chemical applications, such as fire-fighting foams. PFAS are also used in water-, stain-, and oil-repellent coatings for fabrics and paper. (Health Canada, 2019)’

Canadian Standards Association (CSA) Drafts for Review
Standard W211 (Management Standard for Stormwater Systems)
‘This Standard outlines minimum requirements and recommendations for the management of a Stormwater System established by an Operating Authority. It provides a standardized guidance process to manage a Stormwater System to meet regulatory requirements, reflect sound policy decision-making, and demonstrate a high standard of care to minimize legal, environmental, social and economic risks especially given a changing climate and hydrologic conditions. It also provides a documentation protocol to ensure all changes and decisions made in policy and procedures are well documented and identifies steps for Operating Authorities to internally audit their management system. (CSA, 2021)’

Government of Canada Consultation on New Canada Water Agency
“Canadians want a future with cleaner air and cleaner water for their children and grandchildren. Establishing the Canada Water Agency will help to identify, better coordinate, and address various issues relating to freshwater in Canada. It’s an important part of Canada’s plan to build a cleaner, stronger, more resilient economy, with good, secure jobs now and into the future. I encourage all Canadians to take part in these consultations to help shape the Canada Water Agency.”
