What Makes Cinco Ranch's Water Unique?
Local geology and source profile
Cinco Ranch, Texas, in Fort Bend County — an unincorporated Fort Bend County master-planned community adjacent to Katy and Sugar Land, a major west Houston exurban corridor — receives its municipal water from Fort Bend County Municipal Utility Districts (MUDs) or Katy Water, drawing from the Brazos River (Fort Bend County) and/or the Gulf Coast Aquifer through district wells.
The very hard 276 mg/L hardness and high TDS of 737 mg/L reflect the west Houston corridor's typical Fort Bend County supply character. The Brazos River at Fort Bend County carries drainage from the Edwards Plateau (Cretaceous Edwards Limestone and Austin Chalk — high-calcium marine carbonate) and the calcareous Gulf Coastal Plain (Eocene Wilcox and Yegua Formations). The Gulf Coast Aquifer in Fort Bend County is also calcareous, contributing Chicot-Evangeline aquifer groundwater with very high calcium-sulfate loading.
At 276 mg/L with TDS 737, Cinco Ranch's water is very hard. A water softener is essential. Scale builds rapidly in all appliances, and water heaters have greatly shortened lifespans without softening. The PFAS level of 8.9 ppt warrants a certified reverse osmosis drinking water filter — Ellington Field (Houston — AFFF in the Brazos-Buffalo Bayou watershed), the Fort Bend County suburban development PFAS corridor, and the west Houston industrial PFAS complex contribute to Cinco Ranch's elevated readings.
Geology & Source: Cinco Ranch in Fort Bend County draws from the Fort Bend MUD or Katy Water on the Brazos River system (Fort Bend County) or Gulf Coast Aquifer wells — the Brazos drains the Edwards Plateau (Cretaceous Austin Chalk, Edwards Limestone) and the Gulf Coastal Plain calcareous — Texas Brazos River Edwards Plateau-Gulf Coastal Plain carbonate drainage produces very hard water at 276 mg/L with TDS 737 mg/L in this Fort Bend County Texas community.
