Your local water, explained
Texas water quality reports
Start with your county, then choose your city and the water provider on your bill. Compare real utility results before choosing a whole-home filter or softener.
Three county hubs. Six city reports. Each utility keeps its own numbers.

Coverage starts with the utilities listed below. Other providers need their own reports.
Harris County
Harris County has many water suppliers. Begin with the provider on your bill: this first report covers Houston Water’s Main System, while other Houston systems and municipal utility districts need their own reports.
Browse reports → TexasDallas County
Dallas County water quality depends on the supplier. Compare Dallas, Irving, Garland and Grand Prairie reports here; the cities can share source water while reporting different results in their own distribution systems.
Browse reports → TexasBexar County
For a Bexar County home served by SAWS Main System, the utility’s typical hardness range makes softening worth planning for. Other utilities and private wells need their own results.

Houston
A hard average does not describe every Houston tap.
Browse reports → CitySan Antonio
Filtration for taste and odor. Softening for mineral scale.
Browse reports → CityDallas
Current contaminant results. Clearly dated hardness guidance.
Browse reports → CityIrving
Use Irving’s local results, not a neighboring city’s average.
Browse reports → CityGarland
A measured hardness range, with a practical scale-control plan.
Browse reports → CityGrand Prairie
A city-specific report across county boundaries.
Browse reports →More Texas areas can be added as their utility reports are verified. A county or city name alone does not confirm your water supply.
What this means for your home
Utility data is a starting point. It is not a test of your tap or a live advisory.
We keep each utility’s results separate, show the reported sample year, and distinguish averages, maxima and tap-sampling percentiles. Hardness classifications use USGS ranges. Missing data stays unknown.
Your water → your home → your system
Turn your report into a plan for your home.
Choose the system size, keep useful existing equipment, and review your filtration goals.
