Good
Graded against Health Canada drinking water guidelines
Edmundston hardness is 252 mg/L — pitcher filters improve taste but will not soften water. Size a metered whole-house softener for scale, and add under-sink carbon for drinking chlorine.
OpenStats pick for Edmundston’s 252 mg/L hardness — metered whole-house softener sized for very hard Canadian tap water
Edmundston: under-sink carbon for drinking water (chlorine 0.9 mg/L) — does not remove hardness minerals
Edmundston’s 0.9 mg/L chlorine — bestselling shower filter on Amazon.ca
Verify 252 mg/L hardness at your tap before buying salt and sizing a softener

Edmundston's drinking water earns Grade B (Good). Hardness is 252 mg/L (very hard), and pH is 7 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 0.7 mg/L against a guideline of ≤ 1.5 mg/L.

Watershed to tap
How Edmundston 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
Edmundston municipal wells / chlorination system
City Public Works: groundwater wells of high quality; treatment limited to chlorine injection for bacteria control plus zinc phosphate for corrosion control. Daily monitoring of reservoirs, wells, and water quality per NB Environment standards.
City aqueduct network with reservoirs; major aqueduct replacement near Iroquois wells (2022). Provincial Clean Water Act monitoring labels the Iroquois/Blanchette system across multiple zones; amalgamated sectors (Saint-Basile, Verret, St. Jacques) appear in provincial sampling.
Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target and very hard water.
Health parameters meet Health Canada limits; turbidity exceeds the typical 1 NTU aesthetic target.
