What Makes Azle's Water Unique?
Local geology and source profile
Azle, Texas, in Tarrant County — a Tarrant County city adjacent to Weatherford and Saginaw on Eagle Mountain Lake in the northwest Dallas-Fort Worth metroplex — receives its water from the City of Azle Water Department or the Parker County utility, drawing from Eagle Mountain Lake and supplemental Parker County well supplies through the north-central Texas distribution.
The extremely hard 367.5 mg/L hardness and very high TDS of 1090 mg/L reflect the Tarrant/Parker County supply's extreme calcareous character — the Permian Cisco Formation and Pennsylvanian Palo Pinto Formation of the Brazos watershed are both highly calcareous carbonate formations, and the arid west Texas-border character of Parker County concentrates minerals through evaporation in surface reservoirs (compare Weatherford TX: 362/1074 in Parker County comparable; Saginaw TX: 365/1085 in Tarrant County comparable; Azle consistent extremely hard from the same Tarrant-Parker County Permian calcareous supply). The Trinity-Brazos watershed — Permian Cisco Formation (highly calcareous — primary hardness contributor), Pennsylvanian Palo Pinto Formation (calcareous — secondary contributor), and Quaternary West Texas alluvium (calcareous — TDS contributor).
At 367.5 mg/L with TDS 1090, Azle's water is extremely hard — a whole-house water softener is essential. A reverse osmosis system is strongly recommended for drinking. The PFAS level of 10.8 ppt is very high — a certified filter with PFAS removal is strongly recommended — the Tarrant County DFW metro industrial and military (NRRF Fort Worth legacy) corridor contributes to Azle's very elevated PFAS readings.
Geology & Source: Azle in Tarrant County draws from the City of Azle Water on Eagle Mountain Lake (Tarrant County, north-central Texas) — the Trinity watershed at Tarrant County is underlain by Permian Cisco Formation (highly calcareous) and Pennsylvanian Palo Pinto Formation (calcareous) — Texas Tarrant County Eagle Mountain Lake Permian supply produces extremely hard water at 367.5 mg/L with TDS 1090 mg/L.
