OpenStats picks for Norfolk — everyday tap water
Norfolk's 115 mg/L supply is relatively soft — filtration is mostly about chlorine taste. A certified pitcher or compact under-sink unit is enough for most homes.

Reading this page
Norfolk's drinking water earns Grade C (Fair). Hardness is 115 mg/L (moderate), and pH is 7.3 against Health Canada's 6.5–8.5 guideline.
Lead at 0.3 μg/L is below the 5 μg/L maximum, and fluoride is 0.7 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.

Supply and treatment
How Norfolk 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: medium
Source waters
- Lake Erie
- Local groundwater systems
Treatment plants
Norfolk County Lake Erie and well-based systems
Single-tier Norfolk County operates multiple drinking-water systems including Lake Erie surface plants (e.g. Port Dover / Simcoe area systems) and groundwater systems in inland communities.
Distribution
County-scale utility with distinct subsystems rather than one plant for the whole municipality.
Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.
One or more parameters exceed a Health Canada drinking water guideline or turbidity target.
