Long-term drinking water advisories affecting First Nations water systems – Progress on the 78 long-term drinking water advisories affecting First Nations as of April 2016, Canada

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Long-term drinking water advisories affecting First Nations water systems indicator provides a snap shot of the Government of Canada's progress towards eliminating the 78 long-term drinking water advisories affecting First Nations water systems financially supported by Indigenous Services Canada. It is used to assess progress towards the 2016–2019 Federal Sustainable Development Strategy target of lifting all long-term drinking water advisories on federally funded public water systems on reserves by March 2021. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.
