Deep dive for households

Edmundston drinking water starts as groundwater from wells. The named sources on the utility record are Iroquois / Blanchette wellfield (near Rivière Iroquois / chemin Olivier-Boucher), Additional designated watersheds serving Edmundston (Blanchette Brook, Iroquois River, Trois-Milles Brook, and related Madawaska/Verret tributaries). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Edmundston municipal wells / chlorination system before it enters city pipes. 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.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. 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.

One detail that makes Edmundston water feel local: The Iroquois/Blanchette agricultural watershed was the focus of a multi-agency source-protection pilot because it feeds Edmundston’s wells,and the city still needs only chlorine plus corrosion control, not a full filtration plant. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
