What Makes Elkhart's Water Unique?
Local geology and source profile
Elkhart, Indiana, the Elkhart County seat on the St. Joseph River — the 'RV Capital of the World' (Elkhart County produces over 80% of all recreational vehicles manufactured in the United States), a major northern Indiana manufacturing and healthcare hub, home of Elkhart General Hospital — draws its municipal water supply from the St. Joseph River Valley alluvial aquifer and the Elkhart County calcareous glacial outwash via the City of Elkhart Water and Sewer Division. Water hardness in Elkhart measures 278.5 mg/L — classified as very hard.
Elkhart's very hard supply reflects the Elkhart County calcareous glacial terrain. The St. Joseph River Valley aquifer and glacial outwash in Elkhart County are composed of: Wisconsin Age Valparaiso Moraine calcareous outwash (deposited by the Laurentide Ice Sheet advancing from the Lake Michigan Lobe — calcareous-rich from the Michigan–Ontario Devonian–Silurian dolomite and limestone terrain transported south); the Silurian Niagara Dolomite subcropping in northern Indiana (calcareous Silurian dolomite of the Michigan Basin margin — contributing dissolved calcium and magnesium to the river alluvium); and the Ordovician Maquoketa Shale calcareous carbonate. The concentrated calcareous Wisconsin Age outwash and Silurian dolomite subcrop produce the very hard 278.5 mg/L at Elkhart.
At 278.5 mg/L, Elkhart residents face significant hard water challenges. Scale deposits form rapidly on all fixtures and tile — monthly descaling with citric acid solution is essential maintenance. City of Elkhart Water and Sewer Division consistently delivers water meeting all Indiana IDEM and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the St. Joseph River Valley alluvial aquifer and the Elkhart County calcareous glacial outwash via the City of Elkhart Water and Sewer Division — the Elkhart County Indiana Wisconsin Age calcareous glacial outwash (the Teays Valley buried valley sub-basin and the St. Joseph River alluvial recharge); very hard supply at 278.5 mg/L in Elkhart County.
