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)
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.
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.
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.
