How this indicator was calculated

Note: The Environmental Performance Index of water quality is calculated using the Canadian Council of Ministers of the Environment's Water Quality Index and is based on different water quality parameters and guidelines than the Canadian Environmental Sustainability Indicators (CESI) national freshwater indicator. Care should be taken when comparing these data to the CESI freshwater indicator because it is challenging to develop assessments of environmental quality at the international level based on comparable and sufficient data collection.
