How to read this
Rottnest Island doesn't have its own published sampling point. The supplies shown here are the closest monitored locations by distance — a useful proxy, but not a guarantee of the exact source feeding your street, since much of Perth draws on the blended Integrated Water Supply Scheme. For the authoritative picture, check with Water Corporation.
Readings come from the Water Corporation of WA Drinking Water Quality Annual Report 2023-2024, ranked within each supply's region. Suburb locations: GeoNames (CC BY 4.0).
