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…
The MPCA and its many partners collect a wide variety of data on environmental conditions and pollution sources.
The MPCA has developed guidance on a number of topics to assist real estate developers, environmental engineers, remediation consultants, and others in addressing brownfields and contaminated sites.…
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.
Pollutant and runoff maps and data for major watersheds; watershed monitoring and assessment reports.
The MPCA strives to ensure all people in Minnesota have clean air, regardless of where they live or work.
Understanding small-scale differences in air pollution is important for minimizing exposure to harmful air pollutants, particularly for vulnerable communities.
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.
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.
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.
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.
Guidance for submitting data to MPCA Remediation Division programs: Superfund, Site Assessment, Petroleum Remediation, Brownfields, RCRA Remediation, Closed Landfill, and Integrated Remediation.
The Regional Haze Rule requires states to improve visibility in our nation's national parks and wildernesses (Class I areas) and restore them to natural visibility conditions by 2064.
Ready-to-run meteorological data suitable for AERMOD.
The MPCA's regulatory, cleanup, and monitoring programs create and maintain spatial data that serve our environmental protection work and can be shared with partners and researchers.
Minnesota is a national leader in ensuring healthy air quality. The Clean Air Act requires states to take significant responsibility for preventing and controlling air pollution. States must pass…
MPCA’s community air monitoring pilot grant program will provide $4.85 million to build more networks of community air sensors in the Twin Cities metro area.
The MPCA uses the Environmental Quality Information System (EQuIS) to store water quality data from more than 17,000 Minnesota sampling locations.
When people think of sources of air pollution, they typically think about buildings with big smokestacks like power plants and factories. Only about a quarter of the air pollution in Minnesota comes…
