Metal mining effluent quality – Percentage of regulatory data submitted by metal mines within authorized limits, Canada

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Metal mining effluent quality indicator presents the annual percentage of reported test results for all metal mines that are within authorized limits for deleterious substances, pH levels and fish toxicity from 2003 to 2017. The indicator helps Environment and Climate Change Canada evaluate the degree of compliance with the regulations and the effectiveness of pollution prevention and control technologies, practices and programs within the metal mining sector. This indicator summarizes the results achieved since the Metal Mining Effluent Regulations came into effect in June 2002. 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.
