MPCA established a network of long-term biological monitoring stations that represent a variety of stream types in their most natural condition.

Permitted waste facilities, waste projects, and waste haulers in Minnesota must submit regular reports to the MPCA.

The MPCA has actively been developing methods and building capacity to improve our ability to monitor and assess wetlands to protect and restore them.

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 monitors and assesses lakes around the state to determine if they meet water quality standards.

The MPCA monitors water quality in rivers and streams is several different ways around the state.

A training and certification program for evaluating aquatic life in Minnesota’s rivers and streams.

For more than 50 years, volunteers have gathered critically important water clarity data on Minnesota lakes and streams.

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.

As part of the PFAS pollution prevention law called Amara’s Law, manufacturers are required to report intentionally added PFAS in products sold in Minnesota and pay a fee. The Minnesota Pollution Control Agency has extended the reporting due date to Sept. 15, 2026.

The Watershed Pollutant Load Monitoring Network (WPLMN) is a partnership that collects data on water quality and flow in Minnesota.

Air quality dispersion modeling uses a computer model to estimate air pollution concentrations from regulated facilities and other sources of pollution.

Local governments with SSTS programs submit information to the MPCA each year on SSTS permitting and compliance trends for the previous calendar year. The information helps the agency with long-range planning efforts.

The health of Minnesota's large rivers is a reflection of how well we are protecting overall water quality.

Pollutant and runoff maps and data for major watersheds; watershed monitoring and assessment reports.

The MPCA is planning new rules governing air quality. The main purpose is to adopt new rules to implement and govern regulation of facilities that emit air toxics.

Air sensors are instruments that measure air quality conditions in near real time.

New rules establish a program for the MPCA to collect information about products containing intentionally added PFAS and establish fees to be paid upon submission of required reporting.

The amount of hazardous waste you generate will dictate your waste generator status.
