What Makes Glenn Heights's Water Unique?
Local geology and source profile
Glenn Heights, Texas, in Dallas County — a Dallas County city adjacent to DeSoto and Cedar Hill in the south Dallas-Fort Worth metroplex — receives its water from Dallas Water Utilities or a local Municipal Utility District (MUD), drawing from Lake Ray Hubbard and other Dallas system reservoirs on the Trinity River through the north-central Texas metro distribution.
The hard 181.5 mg/L hardness and TDS of 428.9 mg/L reflect the Dallas County Trinity River supply's hard calcareous character — the Cretaceous Taylor Marl and Austin Chalk are both calcareous formations of the Blackland Prairie region, contributing significant dissolved calcium to the watershed (compare DeSoto TX: 180/425 in Dallas County comparable; Cedar Hill TX: 182/432 in Dallas County comparable; Glenn Heights consistent hard from the same Dallas County Trinity River-Cretaceous calcareous supply). The Trinity watershed at Dallas County — Cretaceous Taylor Marl (calcareous — primary hardness contributor), Cretaceous Austin Chalk (calcareous — secondary contributor), and Quaternary Trinity alluvium (calcareous — TDS contributor).
At 181.5 mg/L with TDS 429, Glenn Heights' water is hard — scale builds in appliances and fixtures over months. Quarterly descaling is appropriate. The PFAS level of 6.9 ppt warrants a certified drinking water filter — the Dallas County north-central Texas industrial and urban corridor contribute to Glenn Heights' elevated PFAS readings.
Geology & Source: Glenn Heights in Dallas County draws from Dallas Water Utilities on Lake Ray Hubbard (Dallas County, north-central Texas) — the Trinity River at Dallas County is underlain by Cretaceous Taylor Marl (calcareous) and Cretaceous Austin Chalk (calcareous) — Texas Dallas County Trinity River Cretaceous calcareous supply produces hard water at 181.5 mg/L with TDS 428.9 mg/L.
