Range across supply zones: 246–320 mg/L.
The Burbank figure comes from State Water Resources Control Board lab results for the Burbank water department, using treatment-plant samples. The median of 27 results from 2021 to 2026 is 300 mg/L as CaCO3 (17.5 gpg), within a range of 246 to 320 mg/L. This is very hard water. Scale builds quickly on heaters and glassware, and a softener is worth considering.
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).
