What Makes Robinson's Water Unique?
Local geology and source profile
Robinson, Texas, in McLennan County — a McLennan County city adjacent to Waco and Woodway in the Brazos Valley of central Texas — receives its water from the City of Robinson Water Department or Waco Water system, drawing from Tradinghouse Creek Reservoir or the Brazos River through the central Texas distribution.
The extremely hard 333 mg/L hardness and very high TDS of 950.4 mg/L reflect the McLennan County Brazos supply's extreme calcareous character — the Cretaceous Austin Chalk and Eagle Ford Shale are highly calcareous formations in the Waco area Cretaceous outcrop belt, and the Brazos River at Waco concentrates minerals from its extensive arid-to-semiarid catchment (compare Waco TX: 326/930 in McLennan County comparable; Woodway TX: 337/960 in McLennan County comparable; Robinson consistent extremely hard from the same McLennan County Tradinghouse Creek Cretaceous calcareous supply). The Brazos watershed at McLennan County — Cretaceous Austin Chalk (calcareous — primary hardness contributor), Cretaceous Eagle Ford Shale (slightly calcareous — secondary contributor), and Quaternary Brazos alluvium (calcareous — TDS contributor).
At 333 mg/L with TDS 950, Robinson'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 10.1 ppt is very high — a certified filter with PFAS removal is strongly recommended — the McLennan County Waco area industrial and military (former Connally AFB) legacy contributes to Robinson's very elevated PFAS readings.
Geology & Source: Robinson in McLennan County draws from the City of Robinson Water on Tradinghouse Creek Reservoir (McLennan County, central Texas) — the Brazos watershed at McLennan County drains Cretaceous Austin Chalk (calcareous) and Cretaceous Eagle Ford Shale (slightly calcareous) — Texas McLennan County Tradinghouse Creek Cretaceous calcareous supply produces extremely hard water at 333 mg/L with TDS 950.4 mg/L.
