What Makes Greenwood's Water Unique?
Local geology and source profile
Greenwood, Indiana, in Johnson County south of Indianapolis — a major Indianapolis south suburban community that doubled in population in the 2000s–2010s, home of the Greenwood Park Mall and a major corporate distribution and retail corridor along US 31 — draws its municipal water supply from the White River Valley alluvial aquifer via the City of Greenwood Water Department, pumping from Johnson County calcareous glacial outwash wells. Water hardness in Greenwood measures 209 mg/L — classified as very hard.
Greenwood's very hard supply reflects the Johnson County calcareous glacial terrain. The White River Valley alluvial aquifer in south Indianapolis–Greenwood area is recharged by: the Johnson County Wisconsin Age glacial till and outwash (Tipton Till Plain calcareous till — transported from the calcareous Great Lakes limestone terrain by the Laurentide Ice Sheet, among the most calcareous glacial deposits in Indiana); the Silurian and Devonian dolomite subcropping under Johnson County (the Wabash Valley dolomite of the East-Central Indiana Arch — soluble dolomite supplying additional dissolved calcium and magnesium); and the White River alluvial calcareous sand and gravel aquifer recharge. The Johnson County calcareous terrain produces the very hard 209 mg/L supply at Greenwood.
At 209 mg/L, Greenwood 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 Greenwood Water Department consistently delivers water meeting all Indiana IDEM and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the White River Valley alluvial aquifer via the City of Greenwood Water Department — the Johnson County Indianapolis south suburban calcareous glacial outwash of the White River Valley; hard supply at 209 mg/L — reflecting the Johnson County calcareous Wisconsin Age glacial outwash recharge in the south Indianapolis suburban corridor.
