The MPCA uses the Environmental Quality Information System (EQuIS) to store water quality data from more than 17,000 Minnesota sampling locations.
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.
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.
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.
Guidance for submitting data to MPCA Remediation Division programs: Superfund, Site Assessment, Petroleum Remediation, Brownfields, RCRA Remediation, Closed Landfill, and Integrated Remediation.
Ready-to-run meteorological data suitable for AERMOD.
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.
Volunteer water monitors collect valuable data used by agencies and organizations across the state to protect and manage Minnesota’s waters.
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…
To reduce the pollution that causes climate change, Minnesota has set goals to cut our collective greenhouse gas (GHG) emissions and track progress.
Surface water assessment grants (SWAG) provide local organizations and citizen volunteers with funds to complete the monitoring needed to meet assessment requirements on Minnesota lakes and streams. Assessment is usually the first step in protecting or restoring surface waters.
Contaminated land creates significant problems for our health, environment, and economy in Minnesota. By cleaning up problem areas and protecting against future contamination, we can make land safe…
Environmental information and permits that affect businesses that paint, coat, or strip surfaces.
The MPCA works with city and county governments, watershed districts, consultants, and others on monitoring, protecting, and restoring water quality. This is a repository of guidance and technical resources for agency partners.
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.
The MPCA monitors and assesses lakes around the state to determine if they meet water quality standards.
The MPCA will analyze varying background sulfate levels across Minnesota, which could inform our implementation of the wild rice sulfate water quality standard.
Under the federal Clean Water Act, states must designate beneficial uses for all waters and develop water quality standards to protect each use.
