What Makes Forest Hill's Water Unique?
Local geology and source profile
Forest Hill, Texas, in Tarrant County — a Tarrant County city adjacent to Fort Worth and Everman in north-central Texas — receives its water from the Fort Worth Water system, drawing from the Trinity River or Eagle Mountain Lake (Tarrant County) through the Fort Worth metro distribution.
The extremely hard 270.5 mg/L hardness and TDS of 717.2 mg/L reflect the north-central Texas Tarrant County Trinity River supply's extreme calcareous character — the Cretaceous Comanche Peak Limestone and Pennsylvanian Strawn Formation produce extremely hard water in the Fort Worth metro, compounded by the semi-arid Texas evaporative concentration (compare Borger TX: 271.5/721 on the Canadian River Permian; Forest Hill comparable hardness from the Trinity River Cretaceous limestone). The Trinity River at Tarrant County — Cretaceous Comanche Peak Limestone (calcareous — primary hardness contributor), Pennsylvanian Strawn Formation (calcareous — secondary contributor), and Quaternary Trinity River alluvium (calcareous — TDS contributor).
At 270.5 mg/L with TDS 717, Forest Hill's water is extremely hard. A water softener is essential to prevent severe scale damage. A reverse osmosis system is required for drinking water. The PFAS level of 8.8 ppt warrants a certified drinking water filter — the Tarrant County Fort Worth industrial and military corridor contribute to Forest Hill's elevated PFAS readings.
Geology & Source: Forest Hill in Tarrant County draws from the Fort Worth Water on the Trinity River or Eagle Mountain Lake (Tarrant County, north-central Texas) — the Trinity River at Tarrant County drains the West Texas Rolling Plains (Cretaceous Comanche Peak Limestone — calcareous) and Pennsylvanian Strawn Formation (calcareous) — Texas Tarrant County Trinity River Cretaceous-Pennsylvanian calcareous supply produces extremely hard water at 270.5 mg/L with TDS 717.2 mg/L.
