Water system Vaughan Distribution System
Worth a closer look
Recent public records include a few items that deserve attention.
Worth knowing day to day
Hardness, sodium, and similar day-to-day readings are missing for Vaughan Distribution System because it did not join the provincial monitoring program that produces these cards — so there is no data to show.

What's behind these numbers
Years covered: 2024-25, 2023-24, 2022-23, 2021-22.
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.
116 over-limit tests in recent records.
- 16,008 recent test results processed.
- Parameters involved: Escherichia Coli, Lead, Total coliform.
Incident records
Incident records are required system filings — not a count of taps affected, and not automatically a drinking-water emergency.
- 146 incident records in public records — not a count of taps affected.
Conviction matches
Matching is by name only. Read the detailed record before treating this as a conclusion about this system.
- Matched conviction records: 1.
- Conviction matches use exact name matching only; an absence here means no matched conviction record in the recent local summary data, not a proven absence of any conviction.
