What Makes Fort Campbell North's Water Unique?
Local geology and source profile
Fort Campbell North, Kentucky, in Christian County — the Fort Campbell military installation community adjacent to Hopkinsville and Clarksville TN on the Kentucky-Tennessee border — receives its water from the Fort Campbell Water System, drawing from the Cumberland River or Barkley Lake (Christian County) through the Fort Campbell distribution.
The very hard 214.5 mg/L hardness and TDS of 522.3 mg/L reflect the southwest Kentucky Christian County Cumberland River Nashville Basin supply's very hard calcareous character — reflecting the Ordovician Ridley Limestone and Nashville Dome calcareous dissolution that defines the Tennessee-Kentucky border zone water hardness. The Cumberland River at Christian County — Ordovician Ridley Limestone (highly calcareous — primary hardness contributor from the Nashville Basin carbonates), Mississippian Fort Payne Chert (slightly calcareous — secondary contributor), and Ordovician Lebanon Limestone (calcareous — tertiary contributor).
At 214.5 mg/L with TDS 522, Fort Campbell North's water is very hard. A water softener is strongly recommended to prevent rapid scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 6.5 ppt warrants a certified drinking water filter — Fort Campbell itself (Christian County — AFFF, on-post military AFFF use) is the primary contributor to the elevated PFAS readings.
Geology & Source: Fort Campbell North in Christian County draws from the Fort Campbell Water System on the Cumberland River or Barkley Lake (Christian County, southwest Kentucky) — the Cumberland River at Christian County drains the Nashville Basin (Ordovician Ridley Limestone — highly calcareous) and Mississippian Fort Payne Chert — Kentucky Christian County Cumberland River Nashville Basin Ordovician calcareous watershed produces very hard water at 214.5 mg/L with TDS 522.3 mg/L.
