Brooklyn Center Water Hardness & Quality Report (2026)

Brooklyn Center, Minnesota, in Hennepin County — a major north Minneapolis inner suburban community (Brooklyn Center is a significant first-ring north Minneapolis suburb — an older 1950s–1970s post-WWII suburban community that has undergone dramatic demographic change since the 1990s, transitioning from a predominantly white working-class suburb to one of the most ethnically diverse communities in Minnesota), a diverse Hennepin County community with a significant African-American (particularly Somali-American and Liberian-American), Hmong-American, Latino-American, and East African immigrant population (Brooklyn Center is one of the most ethnically diverse communities in the Twin Cities metro), made nationally prominent following the April 2021 fatal police shooting of Daunte Wright during a traffic stop (a moment that brought national attention to police reform issues during the Derek Chauvin trial), adjacent to Brooklyn Park and Crystal in the north Hennepin County corridor — draws its municipal water supply from the Prairie du Chien–Jordan aquifer via the City of Brooklyn Center Water Division. Water hardness in Brooklyn Center measures 180.5 mg/L — classified as hard.

Brooklyn Center's hard supply reflects the north Hennepin County Twin Cities bedrock aquifer's calcareous dolomite character. The Prairie du Chien–Jordan aquifer draws from the Ordovician Prairie du Chien Dolomite and Cambrian Jordan Sandstone (calcareous). City of Brooklyn Center applies limited softening, producing the hard 180.5 mg/L.

At 180.5 mg/L, Brooklyn Center residents face regular hard water challenges. Monthly descaling and water softeners are recommended. City of Brooklyn Center Water Division consistently delivers water meeting all Minnesota PCA and EPA Safe Drinking Water Act requirements.
