What Makes Rendon's Water Unique?
Local geology and source profile
Rendon, Texas, in Tarrant County — a Tarrant County unincorporated community adjacent to Burleson and Forest Hill in north-central Texas — receives its water from the Tarrant Regional Water District, drawing from the Trinity River or Eagle Mountain Lake (Tarrant County) through the Fort Worth metro distribution.
The hard 199 mg/L hardness and TDS of 481.5 mg/L reflect the north-central Texas Tarrant County Trinity River supply's hard calcareous character — softer than Forest Hill TX (270.5/717) in the same Tarrant County because Rendon is in a different distribution zone with more diluted Trinity River blend (compare Forest Hill TX: 270.5/717; Rendon significantly softer from the south Tarrant County blended supply). 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 199 mg/L with TDS 482, Rendon's water is hard. A water softener is recommended to prevent scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 7.3 ppt warrants a certified drinking water filter — the Tarrant County Fort Worth industrial corridor contribute to Rendon's elevated PFAS readings.
Geology & Source: Rendon in Tarrant County draws from the Tarrant Regional Water District 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 hard water at 199 mg/L with TDS 481.5 mg/L.
