What Makes Pecan Grove's Water Unique?
Local geology and source profile
Pecan Grove, Texas, in Fort Bend County — an unincorporated Fort Bend County community adjacent to Richmond and Sugar Land in the southwest Houston metro — receives its municipal water from the Fort Bend Subsurface Water Authority or Gulf Coast Water Authority, drawing from the Brazos River and local Gulf Coast wells (Fort Bend County, southwest Houston).
The extremely hard 362 mg/L hardness and very high TDS of 1,067.6 mg/L reflect the southwest Houston Gulf Coast supply's intense calcareous and evaporitic character — consistent with neighboring Katy (363 mg/L, TDS 1071) on the same Fort Bend-Harris County Gulf Coast system. The Fort Bend supply includes the Gulf Coast Aquifer (Pleistocene Beaumont Formation — calcareous clay, heavily mineralized) and the Brazos River (draining Permian Wichita Group evaporitic redbeds — gypsum and halite TDS contributor from the Permian Basin upland). The combined Gulf Coast aquifer and Brazos Permian loading produces the extreme Fort Bend hardness and TDS.
At 362 mg/L with TDS 1,068, Pecan Grove's water is extremely hard. A water softener is absolutely essential. Scale forms immediately on all surfaces, appliance lifespans are critically shortened, and water heaters fail within 2 years without treatment. The PFAS level of 10.7 ppt warrants a certified reverse osmosis drinking water filter — Ellington Field (Harris County — AFFF) and the southwest Houston industrial corridor contribute to Pecan Grove's elevated readings.
Geology & Source: Pecan Grove in Fort Bend County draws from the Fort Bend Subsurface Water Authority on the Brazos River and Gulf Coast wells (Fort Bend County, southwest Houston metro) — the Brazos drains Permian evaporitic redbeds (Wichita, Artesia calcareous) with Pleistocene Beaumont Formation aquifer — Texas Fort Bend County Brazos River-Gulf Coast Permian calcareous supply produces extremely hard water at 362 mg/L with TDS 1067.6 mg/L in this Fort Bend County Texas community.
