OpenStats picks for Terrace — lead-aware filtration
Plant averages for Terrace do not guarantee your tap is lead-free. Use NSF/ANSI 53-certified filters (Elite cartridges or Frizzlife under-sink) and a home test kit in pre-1975 housing.

Reading this page
Terrace's drinking water earns Grade B (Good). Hardness is 108 mg/L (moderate), and pH is 8.1 against Health Canada's 6.5–8.5 guideline.
Lead at 0.4 μg/L is below the 5 μg/L maximum, and fluoride is 0.6 mg/L against a guideline of ≤ 1.5 mg/L.
How to use this page: read the headline metric and provincial comparison first, then supply and treatment notes, then the source footer for the underlying dataset.
Watershed to tap
Supply and treatment
How Terrace 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
Groundwater
Research confidence: high
Source waters
- Frank Street Aquifer (three wells — primary)
- Deep Creek (emergency backup)
- Skeena River (emergency backup)
Treatment plants
Frank Street pumping station / chlorination (and fluoridation)
Confined-aquifer wells provide essentially 100% of normal supply; chlorine and fluoride analyzers at Frank Street.
Distribution
Wilson Street reservoirs and Halliwell Reservoir (Terrace Mountain) serve city and some RDKS areas north of town.
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.
