Not quantified
No numeric hardness value verified in the reviewed report
No numeric result
Unknown hardness does not mean soft water. Confirm a current value before sizing and setting a softener.
3.15mg/L
Annual average; range 2.83–3.42
MRDL 4 mg/L
81.7µg/L
Highest reported sample; range 21.3–81.7
MCL 80 µg/L
The report marks no violation. A sample maximum is not the compliance average.
24.9µg/L
Highest reported level; range 7.6–24.9
MCL 60 µg/L
0.46mg/L
Highest reported level
MCL 4 mg/L
The report’s printed range is inconsistent, so only its highest-level value is reproduced.

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
Start with the McAllen system if McAllen Public Utility is the supplier on your bill.
Hidalgo County includes multiple independent water systems. McAllen’s results do not describe every address in Edinburg, Mission, Pharr or unincorporated areas. The 2025 report lists a TTHM sample maximum of 81.7 µg/L while marking no violation; a sample maximum and the required compliance average are different statistics.
A useful local question
No. It is the highest reported sample, not a household measurement or a county average. The utility’s report lists no TTHM violation. Use the original report and its averaging method when interpreting that result.
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.
