▸ 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

Hardness, sodium, and similar day-to-day readings are missing for Cambridge Distribution System because it did not join the provincial monitoring program that produces these cards — so there is no data to show.

  • Parameters involved: Escherichia Coli, Lead, Total coliform.

Incident records
