What Makes Crown Point's Water Unique?
Local geology and source profile
Crown Point, Indiana, the Lake County seat — a major northwest Indiana Chicago suburban city (Crown Point is the Lake County seat and one of the most historically significant northwest Indiana cities; Crown Point is known as the 'Honeymoon Capital of the Midwest' — for decades in the early 20th century, Crown Point was a popular destination for quick marriages because Indiana's marriage laws were less restrictive than in many surrounding states and Crown Point required no waiting period; John Dillinger (one of the most notorious Depression-era bank robbers) escaped from the Lake County Jail in Crown Point in 1934 using a fake wooden gun — one of the most famous jail escapes in American history), home of the historic Old Lake County Courthouse (one of the most beautiful Romanesque Revival courthouse buildings in Indiana — listed on the National Register of Historic Places), a diverse Lake County community with a significant Hispanic-American and working-class suburban population — draws its municipal water supply from the Silurian Dolomite aquifer via the City of Crown Point Water Division. Water hardness in Crown Point measures 245 mg/L — classified as very hard.
Crown Point's very hard supply reflects the Lake County northwest Indiana Silurian dolomite aquifer's highly calcareous character. The Niagaran Dolomite aquifer at Crown Point draws from the Silurian Niagaran Dolomite (highly calcareous). Very limited softening produces the very hard 245 mg/L.
At 245 mg/L, Crown Point residents face significant hard water challenges. Regular water softeners and descaling are strongly recommended. City of Crown Point Water Division consistently delivers water meeting all Indiana DEM and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Silurian Dolomite aquifer (Niagaran Dolomite) via the City of Crown Point Water Division — the Lake County northwest Indiana Chicago suburban Crown Point corridor (Silurian calcareous Niagaran Dolomite — the extremely calcareous northwest Indiana Lake County Chicago Silurian dolomite bedrock aquifer; very limited softening); very hard supply at 245 mg/L in Lake County.
