How to read these numbers
Town-water counts above are for municipal residential systems only — not every school or private system in the area.
They cover over the last 4 years of provincial open data we process (fiscal years: 2024-25, 2023-24, 2022-23, 2021-22).
Over-limit tests are flagged results among 31,571 municipal test results in that window — not a share of homes.
An incident record is a required system filing, not the same as an accident and not a count of taps affected.
