Air Monitoring and Reporting
The Minnesota Pollution Control Agency (MPCA) monitors outdoor air quality throughout Minnesota. There are many reasons to monitor the quality of our outdoor air. Monitoring helps determine major sources of ambient air pollution in Minnesota, addresses ways to reduce pollution levels, and tracks concentrations of ambient air pollution over time. Monitoring data are also used to determine compliance with National Ambient Air Quality Standards (NAAQS) and whether we are protecting the public from the harmful health effects of ambient air pollution.
