Range across supply zones: 428–445 mg/L.
Burnsville's 2024 drinking water report puts hardness at 25 to 26 gpg, which is 428 to 445 mg/L (about 436.6 mg/L at the midpoint). That is very hard water, so scale in water heaters, on glass and around fixtures is likely, and a softener is worth considering. The report prints a range rather than a single average, so the page shows the midpoint.
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).
