What Makes Fort Leonard Wood's Water Unique?
Local geology and source profile
Fort Leonard Wood, Missouri, in Pulaski County — the US Army Engineer School installation in Pulaski County adjacent to Waynesville and St. Robert in south-central Missouri — receives its water from the installation's water system, drawing from the Gasconade River (Pulaski County) through the south-central Missouri water treatment system.
The very hard 202.5 mg/L hardness and TDS of 445.5 mg/L reflect the south-central Missouri Gasconade River Ozark Plateau dolomite supply's intense character — consistent with other Ozark Plateau communities (Rolla: ~200 mg/L; Lebanon: ~210 mg/L). The Gasconade River at Pulaski County drains the Ozark Plateau — Ordovician Gasconade Dolomite (dolomite — primary hardness contributor, namesake formation for the river), Cambrian Roubidoux Formation (calcareous sandstone and dolomite — secondary contributor), and Ordovician Jefferson City Dolomite (dolomite). The Ordovician dolomite-dominant Ozark Plateau produces the very hard south-central Missouri supply.
At 202.5 mg/L with TDS 446, Fort Leonard Wood's water is very hard. A water softener is strongly recommended. Scale builds rapidly on all surfaces, appliance lifespans are significantly shortened, and water heaters require annual descaling without softening. The PFAS level of 6.3 ppt warrants a certified drinking water filter — AFFF use on-installation at Fort Leonard Wood and the south-central Missouri military training corridor contribute to these readings.
Geology & Source: Fort Leonard Wood in Pulaski County draws from the Fort Leonard Wood water system on the Gasconade River (Pulaski County, south-central Missouri) — the Gasconade drains the Ozark Plateau (Ordovician Gasconade Dolomite, Cambrian Roubidoux Formation — calcareous-dolomitic) — Missouri Pulaski County Gasconade River Ozark Plateau dolomite watershed produces very hard water at 202.5 mg/L with TDS 445.5 mg/L.
