The MPCA and its many partners collect a wide variety of data on environmental conditions and pollution sources.
Pollutant and runoff maps and data for major watersheds; watershed monitoring and assessment reports.
Air pollution levels in Minnesota have steadily decreased over the past few decades and currently meet federal standards. But even levels that meet or are below these standards can affect people’s…

Volatile organic compounds (VOCs) are a group of chemicals that can vaporize into air. VOCs are in thousands of daily use products, including paint, varnish, wax, and various cleaning, degreasing,…
To ensure that every person in Minnesota has healthy air to breathe, the MPCA studies, monitors, and regulates air pollutants, primarily in three categories: criteria pollutants, air toxics, and greenhouse gases.
The MPCA strives to ensure all people in Minnesota have clean air, regardless of where they live or work.
Air sensors are instruments that measure air quality conditions in near real time.
Air quality dispersion modeling uses a computer model to estimate air pollution concentrations from regulated facilities and other sources of pollution.
From January through March 2025, MPCA air monitoring data showed elevated lead levels that exceeded national ambient air quality standards near the facility. An MPCA inspection of Gopher Resource in spring 2025 confirmed that the source of the elevated lead levels was addressed.
The MPCA's air monitors continually measure pollutants. With this data, the agency can track pollution trends over time and show if outdoor air meets air quality standards and health benchmarks.
Smith Foundry has ceased operations at its East Phillips facility after an investigation and settlement with the U.S. EPA that the MPCA supported.

The MPCA provides educational information about the status of Minnesota’s air, water, land, and climate and can point you toward beneficial actions you can take as students, teachers, and life-long learners interested in Minnesota’s sustainable future.
Minnesota’s air currently meets all federal air quality standards. However, even levels of air pollution below the standards can affect people’s health, including levels currently found in parts of Minnesota.
The MPCA’s role in regulating data centers The MPCA ensures data centers meet strong environmental standards to protect our air, water, and the health of Minnesotans. We monitor and regulate…
From the days when raw sewage flowed into rivers and lakes, Minnesota’s water bodies have come a long way. However, there is still work to be done in the restoration and protection of our waters.
Understanding small-scale differences in air pollution is important for minimizing exposure to harmful air pollutants, particularly for vulnerable communities.
The Minnesota State Implementation Plan (SIP) is focused on the six criteria air pollutants regulated by national ambient air quality standards (NAAQS): ground-level ozone, fine particles, lead, nitrogen dioxide, carbon monoxide, and sulfur dioxide.
