The Department of Environment in partnership with municipal governments monitors source and tap water quality of public water supplies on a regular basis. The collected data is used to ensure compliance with the "Guidelines for Canadian Drinking Water Quality" and to take appropriate measures to address emerging drinking water quality issues. The data is provided to the public on a regular basis through this web page.
The data below is for all sampling carried out up to September 30, 2016.
To see when your community has been sampled please refer to the Sampling Schedule web page.

The detection limit is the lowest concentration of a substance that can be determined with confidence. Prior to March 31, 2004 analytical results less than the detection limit were reported as half of the detection limit. After March 31, 2004 analytical results less than the detection limit are simply reported as Less Than Detection Limit (LTD) which is considered to be zero for all practical purposes. If you wish to know the detection limit of a particular parameter, please click on the link below to see a list of the various labs, associated parameters and detection limits that have been used during this sampling program. The Department is working to develop better tools to deal with less than detection limit data for statistical analysis and public reporting.
