What Makes Greensburg's Water Unique?
Local geology and source profile
Greensburg, Indiana, in Decatur County — a Decatur County city adjacent to Rushville and Batesville in southeast Indiana — receives its water from the City of Greensburg Water Department, drawing from the Flat Rock River through the southeast Indiana distribution.
The hard 208.5 mg/L hardness and TDS of 451.1 mg/L reflect the Decatur County Flat Rock River supply's hard calcareous character — the Mississippian Salem Limestone and Silurian Niagaran Dolomite are both highly calcareous formations throughout southeast Indiana that define the region's hard water profile (compare Rushville IN: 205/444 in Rush County comparable; Batesville IN: 211/458 in Ripley County comparable; Greensburg consistent hard from the same Decatur County Flat Rock River Mississippian-Silurian calcareous supply). The Flat Rock watershed at Decatur County — Mississippian Salem Limestone (calcareous — primary hardness contributor), Silurian Niagaran Dolomite (highly dolomitic — secondary contributor), and Quaternary glacial drift (calcareous — TDS contributor).
At 208.5 mg/L with TDS 451, Greensburg's water is hard — scale builds notably in water heaters and appliances. Quarterly descaling is appropriate. The PFAS level of 6.5 ppt warrants a certified drinking water filter. Review the City of Greensburg's annual water quality report for the latest contaminant monitoring data.
Geology & Source: Greensburg in Decatur County draws from the Greensburg Water on the Flat Rock River (Decatur County, southeast Indiana) — the Flat Rock watershed at Decatur County drains Mississippian Salem Limestone (calcareous) and Silurian Niagaran Dolomite (highly dolomitic) — Indiana Decatur County Flat Rock River Mississippian-Silurian calcareous supply produces hard water at 208.5 mg/L with TDS 451.1 mg/L.
