OpenStats picks for Kenora — moderate hardness

Kenora at 138 mg/L is hard enough for kettle scale but often below whole-house softener urgency. Carbon filtration for taste plus hardness strips before you overspend.

Research confidence: high

Source waters

  • Lake of the Woods

Treatment plants

  • Kenora Water Treatment Plant (7th Street South)

    Conventional filtration: alum coagulation, upflow pulsator clarification, dual-media anthracite/sand, fluoridation, NaOH pH, chloramination. Rated ~25 ML/d.

Distribution

SCADA-monitored plant supplies city distribution and water-haulage customers.

Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.

Health parameters meet Health Canada limits; turbidity exceeds the typical 1 NTU aesthetic target.
