Water Quality Report
Annual Water Report Water is a highly regulated resource, and the City of Rosemount is dedicated to providing safe and clean drinking water to all of our residents. We work closely with the Minnesota Department of Health to ensure that our water supply continues to meet all Safe Drinking Water Act standards. The City issues an annual Water Quality Report to keep you informed and aware.

Manganese Water Press Release - July 2, 2020
Resources for Residents with Private Wells In addition to the city water system, many rural households in Rosemount rely on private wells for their water supply. Existing manganese data from private water wells in Rosemount indicate 39% of well water samples exceed the drinking water guidance of 100 micrograms per liter. Water softeners or reverse osmosis treatment systems can effectively reduce the manganese.
Later this summer, to help rural residents and the City better understand manganese and other potential contaminants, Dakota County will be sending water test kits to all Rosemount households that use private wells. Homeowners who receive these test kits should collect one sample from their outside untreated water spigots and one inside from the primary drinking water tap. The residents can mail the water samples to the laboratory for analysis of manganese, nitrate, chloride, arsenic and lead, free of charge. When the results are available, Dakota County staff will send each participant their individual results.
