Water quality monitoring
Find water quality data
Data on water quality and quantity throughout the Yukon is available through the Water Data Explorer. The Water Data Explorer allows you to;
- view a map of monitoring locations for water quality and other data;
- visualize these data in plots and maps;
- and download data.
Other direct sources of water quality data include:
Water data networks

Yukon water quality standards
A variety of guidelines and regulatory-imposed standards are available to assess water quality data for protection of aquatic life or suitability of water to drink. Those commonly applied in the Yukon include:
- Yukon Guide for Developing Water Quality Objectives and Effluent Quality Standards for Quartz Mining Projects
- Implementation Plan for the Yukon Guide for Developing Water Quality Objectives and Effluent Quality Standards for Quartz Mining Projects
- Fact Sheet on the Yukon Guide for Developing Water Quality Objectives and Effluent Quality Standards
- Guidelines for developing adaptive management plans in Yukon: Water-related components of quartz mining projects
- Preferred practices for works affecting Yukon waters used to help developers comply with environmental regulations and avoid or mitigate the negative environmental impacts of development activities
- Yukon Contaminated Sites Regulation used to assess risks posed to human and environmental health in groundwater
- Canadian Environmental Quality Guidelines used to assess natural receiving environments
- BC Water Quality Guidelines used to assess natural receiving environments.
- Metal Mining Effluent Regulations: federally regulated standards for water released from a mine
- Federal Environmental Quality Guidelines: referencing health of aquatic life.
- Guidelines for Canadian Drinking Water Quality: Health Canada guidelines to define safe drinking water
- Guidelines for Canadian Recreational Water Quality: public health and safety of recreational waters
Water sampling techniques and protocols
You need to use proper water quality sampling techniques to:
- avoid sample contamination;
- maintain sample integrity through proper preserving; and
- sample from appropriate locations.
Some water sampling guides
- Water Sampling 101: a basic guide to the fundamentals of water quality sampling
- Canadian Council of Ministers of the Environment Protocols Manual: a nationally recognized guide for water quality sampling
- American Society for Testing and Materials Standard Guide: a widely adopted protocol for sampling of groundwater wells
- For sampling groundwater wells specific to the contaminated sites regulations:
