What the numbers refer to
Over-limit tests
Regulatory flags when a monitored result was above an Ontario standard. A count alone does not say how long a result lasted or that every tap was affected.
2 over-limit tests in recent records.
- 8,222 recent test results processed.
- Parameters involved: Total coliform.
Incident records
Incident records are required system filings — not a count of taps affected, and not automatically a drinking-water emergency.
- 5 incident records in public records — not a count of taps affected.
Other public-record context
