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.

More about your local water
What this means for your home
Lakeside, Show Low, Winslow, Holbrook and tribal communities do not share one water report.
This guide summarizes Arizona Water Company’s Lakeside system. Show Low, Winslow, Holbrook, other suppliers and tribal systems need their own reports. A Lakeside-area address alone does not establish the supplier.
A useful local question
Does this report cover all of Navajo County?
No. The measurements here belong to the named Lakeside system. Check the utility on your bill; use its report or a private-well test if your supplier is different.
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.
