What Makes Campbellsville's Water Unique?
Local geology and source profile
Campbellsville, Kentucky, in Taylor County — the Taylor County seat adjacent to Columbia and Greensburg on Green River Lake in south-central Kentucky — receives its water from the Campbellsville Municipal Water Department, drawing from Green River Lake through the south-central Kentucky distribution.
The hard 170.5 mg/L hardness and TDS of 371.4 mg/L reflect the Taylor County Green River supply's hard calcareous character — the Mississippian Ste. Genevieve and Warsaw Limestones are highly calcareous formations in the Kentucky Highland Rim, and the Green River at Campbellsville acquires substantial dissolved mineral content from its extensive limestone drainage (compare Columbia KY: 167/362 in Adair County comparable; Greensburg KY: 173/380 in Green County comparable; Campbellsville consistent hard from the same Taylor County Green River Lake Mississippian calcareous supply). The Green River watershed — Mississippian Ste. Genevieve Limestone (calcareous — primary hardness contributor), Mississippian Warsaw Formation (calcareous — secondary contributor), and Quaternary Green River alluvium (calcareous — TDS contributor).
At 170.5 mg/L with TDS 371, Campbellsville's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 5.5 ppt is moderate — a certified drinking water filter provides added protection. Review the Campbellsville Municipal Water Department's annual report.
Geology & Source: Campbellsville in Taylor County draws from the Campbellsville Water on Green River Lake (Taylor County, south-central Kentucky) — the Green River watershed at Taylor County drains Mississippian Ste. Genevieve Limestone (calcareous) and Mississippian Warsaw Formation (calcareous) — Kentucky Taylor County Green River Lake Mississippian calcareous supply produces hard water at 170.5 mg/L with TDS 371.4 mg/L.
