The Watershed Pollutant Load Monitoring Network (WPLMN) is a partnership that collects data on water quality and flow in Minnesota.
The MPCA studies, monitors, and regulates numerous water pollutants to protect human health and the environment. At the state level, three agencies share the monitoring and control of pollutants:the…
Water quality trades that have been arranged in Minnesota illustrate many opportunities to enhance pollution reduction efforts while offering flexibility and cost savings to regulated municipalities and industries.
Every two years, MPCA creates a list of impaired waters in the state that do not meet water quality standards.
Standard operating procedures (SOPs) reflect how agency staff and contracted partners complete agency-funded field activities.
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.
Water softeners produce much of the chloride that pollutes Minnesota’s waters. An MPCA grant aims to reduce that pollution with water softener replacement rebate programs.
Status of total maximum daily load (TMDL) projects in Minnesota.
Excess nitrate remains a long-term challenge to manage. In our lakes, rivers, and streams, it is toxic to fish and other aquatic life. In drinking water, it can pose a risk to human health,…

The Minnesota Nutrient Reduction Strategy (NRS) compiles the latest science, research, and data and recommends the most effective strategies to reduce nutrients in our waters from both point and nonpoint sources.
Industrial Stormwater Steps to Compliance - Step 3: Facilities requiring permit coverage must assess for pollutants at the facility
Governor Walz appointed Katrina Kessler as MPCA commissioner effective November 1. Kessler has been serving as an assistant commissioner.
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…
The MPCA will analyze varying background sulfate levels across Minnesota, which could inform our implementation of the wild rice sulfate water quality standard.
State will begin engagement next month on an updated framework set to be released in 2025
The MPCA added three bodies of water to the impaired waters list for PFAS contamination. Which are they? How did they get polluted? And how much PFAS does it take to contaminate a body of water?
Improving water quality in Lake George has required treating phosphorus in the water and filtering pollutants out of urban stormwater.
Across the state, water softeners contribute significantly to chloride pollution. Here’s how to make sure your water softener isn’t sending excess salt into the environment
Cleaner water is taking hold across Minnesota this Earth Day as farmers and communities scale up solutions that protect rivers, strengthen soil, and build resilience from headwaters to downstream lakes.
