Your local water, explained
Understand the hardness result for your water supply.
League City's 2026 publication reports 2025 data, including a hard 124 mg/L value at supplier entry point EP002. Use that as source-specific evidence, not a measurement for every home on the city's mixed supply.
Your water → your home → your system
Your water
The report follows your water provider—not your ZIP code or county boundary.
Only the listed water system is summarized here. Choose “Other / not sure” if your bill shows a different supplier.
Confirm the provider on your bill, or choose “Other / not sure” to continue without a matched report.

Municipal utility results; supplier EP002 hardness is separately labelled. Galveston County is not one water system.

Do not label citywide tap hardness. Report has multiple supplies/groundwater wells. Verify home's current blend.

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 ↗

More about your local water
The report distinguishes municipal contaminant results from supplying entry points. It also reports lead as a 90th-percentile statistic with one individual sample above the action level; a low system percentile does not establish the result at your faucet.
A useful local question
No. The report includes 124 mg/L as calcium carbonate for the SEWPP entry point EP002. It is hard on the USGS scale. Confirm your home's current supply and hardness before setting a softener.
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.
