This figure is over 3 years old; hardness may have changed.
The Town of Queen Creek's report is the 2023 consumer confidence report, but the hardness in it was sampled in 2021, so the data is stale. It lists an average of 206 mg/L (12.0 gpg), with a range of 110 to 260 mg/L (6.4 to 15.2 gpg). That is very hard water on average, and scale on heaters and fixtures is likely. A newer report may change the figure.
USGS classes: soft 0–60, moderately hard 61–120, hard 121–180, very hard >180 mg/L.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
