The Town of Sylvan Lake's 2024 treated-water lab certificate shows two zones: 208 mg/L in the Lower Zone and 340 mg/L in the Upper Zone, each from a single sample taken on 15 August 2024. The zone order was read from a garbled certificate, so the labels may be swapped. The values themselves are as printed. Water is hard to very hard, and scale on heating elements is likely.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.

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).
