What Makes Paris's Water Unique?
Local geology and source profile
Paris, Tennessee, in Henry County — the Henry County seat adjacent to Clarksville and McKenzie on the Tennessee River in northwest Tennessee — receives its water from the City of Paris Water Department, drawing from Kentucky Lake (Tennessee River) through the northwest Tennessee distribution.
The hard 170.5 mg/L hardness and TDS of 371.8 mg/L reflect the Henry County supply's hard west Tennessee limestone character — the Mississippian St. Louis Limestone and Devonian Chattanooga Shale are calcareous-slightly calcareous formations in the west Tennessee limestone plateau; the Tennessee River at Kentucky Lake acquires substantial dissolved mineral content from its extensive Tennessee Appalachian and limestone plateau drainage (compare Clarksville TN: 166/361 in Montgomery County comparable; McKenzie TN: 174/382 in Carroll County comparable; Paris consistent hard from the same Henry County Kentucky Lake Tennessee River Mississippian calcareous supply). The Kentucky Lake/Tennessee River — Mississippian St. Louis Limestone (calcareous — primary hardness contributor), Devonian Chattanooga Shale (slightly calcareous — secondary contributor), and Quaternary Tennessee River alluvium (calcareous — TDS contributor).
At 170.5 mg/L with TDS 372, Paris' water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 5.8 ppt warrants a certified drinking water filter. Review the City of Paris' annual water quality report.
