The Clean Water Act established the framework for creating water quality standards and continues to help us protect Minnesota's prized lakes and rivers.

The MPCA provides financial and technical assistance to local government and other water resource managers to address nonpoint-source water pollution.

The MPCA amended Minnesota Rules relating to the grant application process for the solid waste management capital assistance program.

The MPCA is currently recruiting volunteers to measure water clarity in numerous lakes and streams across the state and then report the data back to the agency.

Community wastewater treatment facilities and their operators play a critical role in maintaining a health community and preserving and protecting our waters.

The MPCA will establish a pilot program providing financial assistance to eligible applicants for the purchase of landscaping and snow-removal equipment powered exclusively by electricity.

Every two years, MPCA creates a list of impaired waters in the state that do not meet water quality standards.

Planned amendments to Minn. Rules ch. 7050 affect the Class 1 beneficial use, which protects waters (both surface and groundwater) used as a source for domestic consumption.

Removing of an old dam and restoring a creek's curves are improving habitat and water quality in the Pomme de Terre River Watershed.
