▸ How to read these numbers

Over-limit tests. That is a regulatory flag in the public record. A count alone does not say how long a result lasted, whether it was retested, or that every tap in the building was affected. Open the detailed records for timing and context.
Incident records. Ontario systems must file these reports for many operational signals (sampling flags, instrument notices, follow-ups, and similar). A report is not the same as an “accident,” and a high count does not by itself mean people at this building had a water emergency. Open the detailed records for what was filed.

Worth knowing day to day

Plant averages from the provincial monitoring program (not this year’s report and not your kitchen tap). When enough samples exist from 2019 onward, we prefer that recent window and compare it to the longer record.
