Drinking Water Quality Data

The collected data is used to ensure compliance with the “Guidelines for Drinking Water Quality in Newfoundland and Labrador” 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.
