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 40,006 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.

Open a system page for timing, parameters, and official detail before drawing conclusions.
