What Makes Fort Cavazos's Water Unique?
Local geology and source profile
Fort Cavazos, Texas (formerly Fort Hood), in Coryell County — a major central Texas US Army military installation (Fort Cavazos is one of the largest US Army installations in the world — the primary home of III Armored Corps and the 1st Cavalry Division; renamed from Fort Hood to Fort Cavazos in 2023 to honor Medal of Honor recipient Richard E. Cavazos, the first Hispanic four-star general in US Army history; Fort Cavazos is the largest active-duty armored post in the US military and a critical national defense installation in central Texas), a diverse military community with a population of active-duty soldiers, family members, veterans, and Department of Defense civilian employees representing every state and ethnic background in the United States, adjacent to Killeen and Copperas Cove in the Bell–Coryell County Central Texas corridor, and home of III Armored Corps (the Army's deployable corps headquartered at Fort Cavazos) — draws its municipal water supply from the Stillhouse Hollow Reservoir via the Fort Cavazos Water Department. Water hardness at Fort Cavazos measures 206 mg/L — classified as hard.
Fort Cavazos's hard supply reflects the central Texas Coryell–Bell County Edwards Plateau limestone karst's calcareous character. The Lampasas River watershed (Stillhouse Hollow Reservoir) drains the Cretaceous Edwards and Glen Rose Formations (calcareous limestone karst). Fort Cavazos applies limited softening, producing the hard 206 mg/L.
At 206 mg/L, Fort Cavazos residents face regular hard water challenges. Monthly descaling and water softeners are recommended. Fort Cavazos Water Department consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Stillhouse Hollow Reservoir (Lampasas River watershed) via the Fort Cavazos Water Department (US Army Garrison) — the Bell and Coryell Counties central Texas Fort Cavazos military corridor (Cretaceous calcareous Edwards Limestone and Cretaceous calcareous Glen Rose Formation — the extremely calcareous central Texas Edwards Plateau–Fort Hood limestone karst; limited softening); hard supply at 206 mg/L in Coryell County.
