Health Canada Guidelines for Canadian Drinking Water Quality
Guidelines are established based on current, published scientific research related to health effects, aesthetic effects, and operational considerations. Guidelines (maximum acceptable concentrations or treatment goals) are based on a comprehensive review of the known health effects associated with each contaminant, on exposure levels and on the availability of treatment and analytical technologies. Aesthetic objectives (e.g., for taste or odour) are provided when they play a role in determining whether consumers will consider the water drinkable. Operational guidance values are provided when a substance may interfere with or impair a treatment process or technology (e.g., turbidity interfering with chlorination or UV disinfection) or adversely affect drinking water infrastructure (e.g., corrosion of pipes) (Health Canada, 2022).
Health Canada publishes guidelines and other information on the website Drinking water quality in Canada.

The Walkerton Clean Water Centre (WCWC) is pleased to announce that it will be delivering two virtual courses at the upcoming Assembly of First Nations 4th Annual Water Symposium.
On behalf of the Aboriginal Water and Wastewater Association of Ontario (AWWAO), WCWC will be delivering Managing Drinking Water Systems in First Nations Communities and New Watermain Commissioning. WCWC is proud to work with AWWAO to make this training available to First Nations Chiefs, Councillors, managers and supervisors who have operational responsibility for water systems, and drinking water operators.
The 4th Annual Water Symposium will be held virtually on February 17 and 18, 2021. The theme of the event is “Protecting Water During Uncertain Times”. Access to safe, clean water is more important than ever as the ongoing impacts of the COVID-19 pandemic highlight the uncertainty facing First Nations with respect to water. For more information about the 4th Annual Water Symposium, please visit afn.ca/2021-water-symposium/ or learn more from AWWAO at awwao.org.

Free Small Systems Training from the Government of Canada
‘This site contains water quality training materials that provides basic information that can help a person learn how to operate and maintain a micro-system (water systems serving up to and including 25 people). The training has been developed by Canadian federal departments as part of a multi-barrier approach to providing safe drinking water in areas of federal jurisdiction, including on federal lands, in federal facilities and/or in First Nations communities. This includes Federal government employees working in Canada, as well as Canadian Coast Guard, Canadian Forces personnel, and Canadian diplomatic mission staff working abroad.
The training is provided in two parts: the main training is in a video or e-Learning format with the second part being an accompanying document that can be printed for more in-depth training.’

Pilot Testing Project Helps Address Long-Term Boil Water Advisory
The Walkerton Clean Water Centre (WCWC) recently completed a pilot testing project with Wauzhushk Onigum Nation, helping the community address a long-term boil water advisory that has been in place since 2012.
Wauzhushk Onigum Nation is located on Lake of the Woods in Northwestern Ontario. The lake water has high organics and colour making it a challenging water source for satisfying the requirements of UV disinfection. Before implementing decentralized point-of-entry (POE) systems for a portion of the community, Wauzhushk Onigum Nation worked with WCWC on a pilot testing project. WCWC tested POE technologies for effectiveness in removing turbidity and organics in order to improve UV disinfection. The test results were shared with consultants in the design of the decentralized water systems.
WCWC conducts pilot tests for clients to enhance their understanding of source water characteristics and the performance of treatment processes and alternative treatment options. Bench or pilot scale projects can be undertaken at a client’s location or at the Technology Demonstration Facility in Walkerton.
WCWC has years of pilot testing experience in areas such as natural organic matter, disinfection by-products, iron and manganese treatment, arsenic, and coagulation. Completed pilot testing reports are available on WCWC’s Drinking Water Resource Library, which is a free online portal that assists drinking water professionals in finding information on various topics.
To learn more about WCWC’s pilot testing services, please visit https://wcwc.ca/services/pilot-testing/ or contact us at 866-515-0550.
