Galveston County Water Quality Report
League City data is a starting point—not a county average.
This hub covers League City's municipal report. Its hardness figure is specifically a supplier entry-point measurement; it should not be presented as a test of every League City or Galveston County home.
90th percentile below action level; one individual site exceeded · Action level 15 µg/LA system sampling percentile is not a measurement of your faucet.
Cannot assess high or lowThis does not establish whether PFAS are present or absent. Check compound-specific testing before choosing treatment.
ppm ≈ mg/L; ppb ≈ µg/L; ppt ≈ ng/L in drinking water. Hardness in gpg = mg/L as CaCO₃ ÷ 17.1. ND means not detected at the method’s reporting limit—not zero.
MCL is a maximum contaminant level. MRDL is a disinfectant limit. Lead/copper action levels use system sampling percentiles and are not a safe-tap threshold. TTHM/HAA5 compliance uses locational annual averages.
PFOA/PFOS comparisons use EPA’s 4 ppt values. Historical detections are not a present compliance finding; EPA assesses compliance using running annual averages. Rule implementation is being reviewed. EPA PFAS benchmarks and implementation ↗

What this means for your home
League City's report includes purchased surface water and groundwater supplies. Other Galveston County cities and districts have separate reports. Confirm the retail provider and current incoming hardness before selecting softener settings.
Can the 124 mg/L hardness value be used for all of Galveston County?
No. It is the 2025 measurement for League City's SEWPP supplier entry point EP002. It is classified as hard, but the home's actual supply blend and hardness should be confirmed.
Sources and methodology
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.
