Data & methodology
Data source: Water Corporation of WA Drinking Water Quality Annual Report 2023-2024.
Regional ranking: Each measured parameter is ranked against every other locality in the Perth Region using the typical (mean) reading. Lower readings rank better, except pH where the score is distance from neutral (7).
ADWG safety check: Every reading is independently checked against the NHMRC Australian Drinking Water Guidelines; any value above the limit is flagged regardless of how it compares to neighbours.
