What Makes Mount Pleasant's Water Unique?
Local geology and source profile
Mount Pleasant, Wisconsin, in Racine County — a major southeast Wisconsin Racine suburban and industrial community (Mount Pleasant is a significant Racine County village — a southeast Wisconsin suburb adjacent to Racine proper; Mount Pleasant has become one of the most economically significant communities in Wisconsin in recent years due to the Foxconn Technology Group factory development (in 2018, Foxconn announced a massive $10 billion manufacturing campus in Mount Pleasant — the project, backed by significant Wisconsin state and local tax incentives, was one of the largest economic development deals in Wisconsin history at the time; the Foxconn project had a complex history — originally announced as a facility to employ 13,000 workers producing LCD screens, the project was repeatedly scaled back; by 2024, Foxconn had built some facilities and employed a fraction of the originally promised workforce, and the project's outcome was widely considered a cautionary tale about large industrial incentive packages)); Mount Pleasant is adjacent to SC Johnson's international headquarters in Racine (one of the most iconic corporate campuses in the United States — designed by Frank Lloyd Wright and a National Historic Landmark), a diverse Racine County community — draws its municipal water supply via the Mount Pleasant Utilities. Water hardness in Mount Pleasant measures 134 mg/L — classified as moderately hard.
Mount Pleasant's moderate hardness reflects the southeast Wisconsin Racine County Silurian carbonate aquifer's calcareous character. The Silurian Niagaran Dolomite aquifer at Mount Pleasant draws from calcareous carbonate with effective treatment, producing the moderately hard 134 mg/L.
At 134 mg/L, Mount Pleasant residents encounter moderate scale accumulation. Monthly cleaning is recommended. Mount Pleasant Utilities consistently delivers water meeting all Wisconsin DNR and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Silurian Niagaran Dolomite aquifer via the Mount Pleasant Utilities — the Racine County southeast Wisconsin Racine suburban Mount Pleasant corridor (Silurian calcareous Niagaran Dolomite — the calcareous southeast Wisconsin Racine County Silurian carbonate aquifer; effective treatment); moderately hard supply at 134 mg/L in Racine County.
