MPCA studies shows 75% of Minnesota lakes meet standards for recreation. Clean Water Fund dollars help answer water quality questions.
The MPCA uses the Environmental Quality Information System (EQuIS) to store water quality data from more than 17,000 Minnesota sampling locations.
Community wastewater treatment facilities and their operators play a critical role in maintaining a health community and preserving and protecting our waters.
Chloride is a problem for wastewater facilities and stormwater permittees.
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.
The Root River starts as a drainage ditch in Mower County, then winds 81 miles from intensely farmed areas through more wooded, rolling terrain, and finally empties into the Mississippi River south of La Crosse, Wisconsin.
Online tool showing Minnesota waters failing to meet one or more water quality standards.
Minnesota industrial stormwater permittees in certain industries to monitor for PFAS in their stormwater runoff or snow.
MPCA keeps its public data easily accessible for convenient use.
MPCA seeks public comment on two draft industrial wastewater permits for U.S. Steel Corp.’s Keetac mining area and tailings basin in Keewatin, Minnesota. These permits will improve protections for wild rice waters and human health.
The MPCA will analyze varying background sulfate levels across Minnesota, which could inform our implementation of the wild rice sulfate water quality standard.
Minnesota has a growing salty water problem that threatens its freshwater fish and other aquatic life. Chloride from both de-icing salt and water softener salt gets into lakes and streams, and…
The MPCA is proposing to amend Minnesota Rules governing animal feedlots.
Intense storms of late spring can wash soil and other pollutants into rivers. Producers can use several techniques to protect their soil and water quality.
The Rainy River - Headwaters Watershed covers nearly 1.9 million acres, starting in northern Cook and Lake Counties and flowing west/northwesterly into St. Louis County and the Canadian border waters.
Excess phosphorus is harming Minnesota waters. Phosphorus comes from both regulated and non-regulated sources. A quarter of Minnesota lakes have high levels of phosphorus, which means that they do…
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.
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
Nitrogen management plans help operators of wastewater treatment facilities understand the inputs of nitrogen to their facilities and evaluate options that can reduce the amount of nitrogen discharged.
