Health Canada published the revised lead drinking water guideline in 2019. The document included recommendations for sampling protocols to assess lead exposure such as random daytime and fixed stagnation time sampling. The selection of a sampling protocol will depend on the objective of the sampling (e.g. typical exposure) and building type (e.g., single-family dwellings, large buildings, schools) and factors such as plumbing configuration and water use/consumption patterns. Indigenous Services Canada conducted a sampling survey in Alberta Region to determine community lead levels in schools and daycares ahead of the guideline changes, to identify potential sources of lead, and to evaluate compliance with the updated guideline.

Title: Cyanobacteria and Drinking Water in Canada, Key issues for Public Health

The NCCEH has undertaken an evidence review of Cyanobacteria and Drinking Water: Occurrence, risks, management and knowledge gaps for public health. This presentation will provide the highlights of the report.

Title: Challenges and a Pilot Study on Cyanobacteria and Small Drinking Water Systems

There is a growing concern regarding cyanobacteria in surface waters and the risks of cyanobacteria entering our drinking water treatment systems. This webinar will discuss the challenges and knowledge gaps for…

This presentation was delivered at the 78th CIPHI Ontario Annual Education Conference. It provides an overview of how climate change impacts public health and how public health workers can act at a local level to address climate change challenges.

This presentation, delivered at the Canadian Water Quality Association's (CWQA) Annual General Meeting, discusses opportunities for Public Health and the Drinking Water Treatment Industry to partner in reducing lead exposure.

Canadian Institute of Public Health Inspectors (CIPHI) 82nd Annual National Educational Conference

In January 2016 a US federal state of emergency was declared in Flint Michigan due to elevated lead concentration in the city’s drinking water. This presentation gives an overview of the Flint lead crisis and how regulation was insufficient to protect public health given human error and omission. Comparisons will be made to the Canadian regulatory system and a discussion of the role of lead monitoring in drinking water and blood lead surveillance in Canada will be presented. Effective mitigation strategies for lead in drinking water and implications for public health inspector practice in Canada will be discussed.

Climate change is anticipated to have myriad potential impacts on human health, some of which may be difficult to predict. However, the effects of climate change on ground and surface water, and the concomitant risk to human health through disruptions to drinking water, have been the subject of intensive research, particularly for communities with high quality source water supplies that originate in forested watersheds. Observed and modelled impacts include changes to the quantity of water available, as well as changes in water quality. Of particular concern are the anticipated increases in frequency of sudden shifts between high- vs. low-flow conditions, as well as rapidly changing and increasingly variable water quality, which may pose a severe challenge for drinking water treatment, particularly in small water systems.

This presentation will give a brief overview of…

Update on the NCCPH Small Drinking Water Systems Project

Canadian Institute of Public Health Inspectors (CIPHI) 81st Annual National Educational Conference

National and International agencies establish drinking water guidelines based on objectives which combine health protection, aesthetics, and the efficacy of metal removal. Recent examples of requests by BC agencies to BCCDC around selenium, arsenic, manganese and lead in water illustrate the need to appreciate the objectives and evidence supporting the guideline. Here we review how aggregate exposure is compared to effects on health (or other endpoint), how acceptable population all-source intake is set, and review how water consumption is apportioned within overall acceptable exposure. Lesson: read the fine print.
