Kyle Water Quality Report
Very hard water, with naturally occurring fluoride.
Kyle's 2025 report lists hardness of 275–295 mg/L as calcium carbonate. We suggest filtration plus softening for homes seeking scale control; dedicated fluoride treatment is a separate configuration if that is your goal.

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
Kyle's report distinguishes City-system results from purchased-water supplier data. Its own highest listed TTHM annual compliance value is 67 ppb; a different supplier's result should not be substituted. The City says it does not add fluoride.
A useful local question
Does Kyle add fluoride to its water?
The City says it does not. The 2025 City-system result of 1.83 ppm reflects naturally occurring fluoride and is below the reported 4 ppm primary limit. A standard filter and dedicated fluoride treatment serve different purposes.
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.
