Katy Water Quality: The Real Numbers
Data from the City of Katy 2024 Consumer Confidence Report. Katy uses 100% groundwater from the Gulf Coast Aquifer — no surface water blending like Houston.
| Contaminant | Katy Level | EPA Limit | Status |
|---|---|---|---|
| Hardness | 150-210 ppm | None (not regulated) | Hard — causes scale |
| Free Chlorine | 1.02 ppm | 4 ppm | 26% of limit |
| TTHMs | 30 ppb | 80 ppb | 38% of limit |
| HAA5 | 14 ppb | 60 ppb | 23% of limit |
| Arsenic | 3.5 ppb | 10 ppb | Below limit |
| Lead | 2.69 ppb | 15 ppb | Below limit |
What This Means
Katy's water is safe to drink — it meets all EPA standards. The main issue isn't safety, it's hardness.
- •Hardness at 150-210 ppm causes scale buildup in pipes, water heaters, and appliances. This is the #1 reason Katy homeowners install softeners.
- •Free chlorine — Katy uses free chlorine (not chloramine like Houston), which dissipates faster and is easier to filter. Levels are low at 26% of the EPA limit.
- •Low disinfection byproducts — TTHMs and HAA5 are well below EPA limits. Groundwater systems like Katy produce fewer byproducts than surface water systems.
