Stratford Water Hardness & Quality Report (2026)

Stratford's drinking water is managed by the Town of Stratford, drawing from a local PEI groundwater aquifer — Stratford is the largest town in Queens County PEI, directly across the Hillsborough River from Charlottetown, connected by the Hillsborough Bridge, a rapidly growing suburban community of Prince Edward Island's capital region on the East Royalty-Stratford corridor, one of the fastest-growing municipalities in the Atlantic provinces driven by Charlottetown's rising population and the affordable land values east of the Hillsborough River, home to the Stratford Town Hall and the large new residential developments of the East Royalty-Keppoch corridor. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 188.5 mg/L (11.0 gpg) — classified as very hard by Health Canada, at the harder end of the PEI groundwater range.

Stratford draws from the PEI Carboniferous sandstone aquifer — Prince Edward Island is underlain by the Permian–Carboniferous Charlottetown Formation red sandstone and Pictou Group sandstone/mudstone, a highly permeable aquifer system saturated with dissolved minerals from the calcareous cement and the carbonate-rich groundwater system. At 188.5 mg/L, Stratford's groundwater is harder than the general PEI reference (120 mg/L from reference data), reflecting the specific Charlottetown-area Hillsborough River catchment groundwater zone with its deeper Carboniferous aquifer mineral concentrations and high TDS (644.7 mg/L).

At 188.5 mg/L, Stratford homeowners face significant scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks benefit from periodic inspection.
