What Makes La Homa's Water Unique?
Local geology and source profile
La Homa, Texas, in Hidalgo County — a Hidalgo County unincorporated community adjacent to Mission and McAllen in the lower Rio Grande Valley of south Texas — receives its water from the Hidalgo County Water District or a local utility, drawing from the Rio Grande through the south Texas distribution.
The hard 170.5 mg/L hardness and TDS of 396.9 mg/L reflect the Hidalgo County Rio Grande supply's hard calcareous character — the Rio Grande carries significant dissolved minerals from the Cretaceous Navarro Formation calcareous formations it traverses across the arid Trans-Pecos and Chihuahuan Desert regions (compare Mission TX: 168/390 in Hidalgo County comparable; McAllen TX: 172/402 in Hidalgo County comparable; La Homa consistent hard from the same Hidalgo County Rio Grande Cretaceous calcareous supply). The Rio Grande at Hidalgo County — Cretaceous Navarro Formation (calcareous — primary hardness contributor), Quaternary Rio Grande alluvium (calcareous — secondary contributor), and Holocene valley deposits (calcareous — TDS contributor).
At 170.5 mg/L with TDS 397, La Homa's water is hard — scale builds in appliances and fixtures over months. Quarterly descaling is appropriate. The PFAS level of 6.7 ppt warrants a certified drinking water filter — the Hidalgo County south Texas agricultural and military corridor contributes to La Homa's elevated PFAS readings. Review the water district's annual water quality report for the latest data.
Geology & Source: La Homa in Hidalgo County draws from the Hidalgo County Water on the Rio Grande (Hidalgo County, south Texas) — the Rio Grande at Hidalgo County is underlain by Cretaceous Navarro Formation (calcareous) and Quaternary Rio Grande alluvium (calcareous) — Texas Hidalgo County Rio Grande Cretaceous calcareous supply produces hard water at 170.5 mg/L with TDS 396.9 mg/L.
