Fairfield Water Hardness & Quality Report (2026)

Fairfield Island's drinking water is managed by the City of Abbotsford or the District of Mission, drawing from a local Cascade foothills mountain reservoir — Fairfield Island is a low-lying island neighbourhood in the Fraser River floodplain between Abbotsford and Mission at the north bank of the Fraser River, a rural residential community of acreage properties, hobby farms, and the Fairfield Island Park, historically part of the Fraser Valley agricultural landscape on the fertile alluvial island deposits between the south Mission and north Abbotsford floodplain, a community prone to seasonal flooding in the lower Fraser River valley. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 22.5 mg/L (1.3 gpg) — classified as soft by Health Canada, with TDS of only 36.1 mg/L — reflecting a high-mountain Cascade foothills watershed with essentially zero carbonate content.

Fairfield Island draws from a local Cascade foothills mountain reservoir — potentially the Norrish Creek, Mission Creek, or a similar upper Fraser Valley coastal mountain watershed in the Cascade Range-Coast Mountains transition above the Mission-Abbotsford floodplain. These high-mountain headwater sources drain Jurassic and Cretaceous plutonic granodiorite with essentially zero carbonate content, producing extraordinarily soft water (TDS 36.1 mg/L, hardness 22.5 mg/L) — among the softest water in the Fraser Valley, despite being in an area considerably harder than the Metro Vancouver core supply.

With 22.5 mg/L, Fairfield Island homes are essentially scale-free — occasional kettle cleaning every three months is adequate. Hot water tanks have an outstanding operational lifespan. Health Canada lead and copper precautionary guidance applies, as the ultra-soft water increases corrosive potential for metallic plumbing. The City of Abbotsford/District of Mission provides water quality information at abbotsford.ca and mission.ca.
