Georgetown Water Quality Report
Hard or very hard, depending on the supplying plant.
Georgetown publishes different historical hardness bands for its plant systems: 176–178 or 309–320 mg/L. These support a softener recommendation for scale control, with the supply and current home hardness confirmed first.

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
What this means for your home
The utility's May 2026 guidance distinguishes Lake Georgetown/Southlake from Park/Southside plant data. Do not turn the two bands into one invented citywide average. Annual report results are historical measurements, not a live advisory status.
A useful local question
Why can two Georgetown homes need different softener settings?
They may receive different source blends. The utility publishes hard-water and very-hard-water plant bands. Confirm the provider, supplying plant where available, and current incoming hardness for sizing and programming.
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.
