Groundwater
Research confidence: medium
Summerside municipal well field and treatment
City groundwater wells with disinfection and corrosion control typical of PEI municipal systems; no surface reservoir plant.
City distribution across Summerside’s urban footprint.
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.
