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
Quartzsite’s groundwater report is separate from Parker and other La Paz County systems.
This guide uses Quartzsite’s 2024 report, with older fluoride, arsenic and sodium samples labeled separately. Parker, other public systems and private wells need their own reports. A sodium measurement does not tell you the water’s hardness.
A useful local question
Does Quartzsite’s sodium result mean the water is hard?
No. Hardness measures calcium and magnesium, while sodium is a different dissolved mineral. The reviewed report does not publish numeric hardness. Test hardness before sizing a softener; a conventional softener does not remove sodium.
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.
