OpenStats picks for Trail — moderate hardness

Trail at 120 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 Trail 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

  • Columbia River
  • Bear Creek well

Treatment plants

  • Trail direct filtration water treatment plant

    Direct filtration plant for Columbia River supply, backed by a deep high-producing Bear Creek well.

Distribution

~82.6 km pipe, 8 reservoirs, 5 booster stations, ~3,413 connections. Distinct from Teck's industrial groundwater remediation plant.

All monitored parameters meet Health Canada guidelines.

All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
