OpenStats picks for Abbotsford — moderate hardness

Abbotsford 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.

Supply and treatment

How Abbotsford draws, treats, and distributes drinking water, from municipal and utility publications. Chemistry grades above come from separate parameter records; this section does not invent plant lab figures.

Source type

Mixed surface and groundwater

Research confidence: high

Source waters

  • Norrish Creek (Dickson Lake)
  • Cannell Lake
  • Abbotsford-Sumas Aquifer

Treatment plants

  • Norrish Creek Water Treatment Plant

    Primary regional plant; slow sand and/or ultrafiltration, then chlorination with ammonia addition downstream at Bell Road to form chloramine.

  • Cannell Lake Water Treatment Plant

    UV and chlorine disinfection for Cannell Lake water; ammonia at Cannons Pit; supplements high-elevation Mission areas and backs up Norrish supply.

Distribution

Abbotsford Mission Water & Sewer Commission operates regional sources, treatment, transmission, and two regional reservoirs; Abbotsford and Mission each run their own distribution networks. Groundwater wells in the Abbotsford-Sumas Aquifer augment surface supply.

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.
