Fredericton’s softer 108 mg/L supply is usually about taste, not scale. A compact Elite pitcher is enough for most apartments; add a home test kit if you live in pre-1980 housing and want lead peace of mind at the tap.

Watershed to tap
How Fredericton 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.
Groundwater
Research confidence: high
Fredericton Water Treatment Plant 1
One of two plants treating wellfield groundwater; chlorine for manganese oxidation/disinfection, lime for pH/corrosion control, then filtration.
Fredericton Water Treatment Plant 2
Second plant on the same South Fredericton Aquifer well system.
About 10–11 production wells in Wilmot Park / Queen Square feed two treatment plants, then ~400+ km of watermains, booster stations, and reservoirs serving most households and businesses in the city. Wellfield Protected Area Designation Order (Clean Water Act) regulates land use in Zones A–C around the wells.
All monitored parameters meet Health Canada guidelines.
All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
