What Makes Mount Washington's Water Unique?
Local geology and source profile
Mount Washington, Kentucky, in Bullitt County — a Bullitt County city adjacent to Shepherdsville and Louisville in north-central Kentucky — receives its water from the Bullitt County Water District, drawing from the Salt River (Bullitt County) through the north-central Kentucky distribution.
The moderately hard 133.5 mg/L hardness and TDS of 261.8 mg/L reflect the north-central Kentucky Bullitt County Salt River supply's moderate calcareous character — consistent with other north Kentucky Pennyroyal Plateau communities receiving dissolution from the Mississippian limestone terrain. The Salt River at Bullitt County drains the Pennyroyal Plateau — Mississippian St. Louis Limestone (calcareous — primary hardness contributor), Mississippian Warsaw-Salem Limestone (calcareous — secondary contributor), and Ordovician calcareous formations (calcareous — minor contributor).
At 133.5 mg/L, Mount Washington's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 4.6 ppt warrants a certified drinking water filter — the Bullitt County north-central Kentucky industrial corridor and Louisville metro PFAS legacy sites contribute to Mount Washington's readings.
Geology & Source: Mount Washington in Bullitt County draws from the Bullitt County Water District on the Salt River or Ohio River (Bullitt County, north-central Kentucky) — the Salt River at Bullitt County drains the Pennyroyal Plateau (Mississippian St. Louis Limestone — calcareous) — Kentucky Bullitt County Salt River Mississippian calcareous limestone watershed produces moderately hard water at 133.5 mg/L with TDS 261.8 mg/L.
