Your provider needs its own report.
Continue with your home details for general filtration guidance. We will not use another utility’s numbers as your result.

In drinking water, ppm ≈ mg/L, ppb ≈ µg/L and ppt ≈ ng/L. Calculated hardness in grains per US gallon (gpg) = mg/L as CaCO₃ ÷ 17.118, rounded to one decimal. ND means below the reporting limit, not zero.
MCL is an enforceable contaminant limit; MRDL is a disinfectant limit. A secondary guideline concerns aesthetics. TTHM/HAA5 compliance uses locational running annual averages; read the utility’s notices as well as individual results.
PFAS results are compound-specific. Source monitoring, entry-point samples and tap tests are different. A detected result does not identify every PFAS compound or establish the level at your home. Read the original report for context and current utility notices. EPA PFAS benchmarks and implementation ↗

More about your local water
What this means for your home
Rio Rico and Nogales have separate water suppliers and reports.
This guide summarizes Liberty’s Rio Rico system. Nogales, Patagonia, other systems and private wells need their own results. The 2025 annual report includes arsenic testing from 2022 and PFAS testing from 2023; those dates stay attached to the results.
A useful local question
Does the Rio Rico report apply to Nogales?
Only if the water bill identifies the same Liberty Rio Rico system. City limits and mailing addresses do not identify a water utility; use the supplier’s exact system name.
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.
Different name on your water bill?
The systems covered here publish separate reports. Use the official links to confirm your utility and system. If yours is not listed, choose Other / not sure.
