What Makes Lawrenceburg's Water Unique?
Local geology and source profile
Lawrenceburg, Kentucky, in Anderson County — the Anderson County seat adjacent to Frankfort and Versailles on the Kentucky River in north-central Kentucky — receives its water from the Lawrenceburg Water and Sewer Commission, drawing from the Kentucky River through the north-central Kentucky distribution.
The very hard 214 mg/L hardness and TDS of 520.2 mg/L reflect the Anderson County Kentucky River supply's very hard calcareous character — the Ordovician Lexington Limestone and Mississippian Ste. Genevieve Limestone are highly calcareous formations in the Kentucky Bluegrass region and Highland Rim, and the Kentucky River acquires substantial dissolved mineral content from its extensive limestone drainage (compare Frankfort KY: 210/511 in Franklin County comparable; Versailles KY: 217/529 in Woodford County comparable; Lawrenceburg consistent very hard from the same Anderson County Kentucky River Ordovician calcareous supply). The Kentucky River watershed — Ordovician Lexington Limestone (highly calcareous — primary hardness contributor), Mississippian Ste. Genevieve Limestone (calcareous — secondary contributor), and Quaternary Kentucky River alluvium (calcareous — TDS contributor).
At 214 mg/L with TDS 520, Lawrenceburg's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 6.5 ppt warrants a certified drinking water filter. Review the Lawrenceburg Water and Sewer Commission's annual report.
