Water Quality Improvements

Dramatic water quality improvements in the Twin Cities reach of the Mississippi River resulted in large part from decades of upgrades to the region's wastewater collection and treatment system, operated by Metropolitan Council Environmental Services (MCES). The online brochure "100+ Years of Water Quality Improvements in the Twin Cities" (PDF) presents a chronology of these river improvements.

Printed copies of the brochure are available by calling MCES at 651-602-1005.
