London water quality test results - municipal bylaws
In London, Ontario, homeowners can access official municipal drinking-water reports and guidance for private well testing to check water quality for household use. This guide explains where the city publishes drinking-water test results, how private well owners can get tests and results, and which municipal or public-health offices handle complaints and enforcement.
Where municipal drinking-water test results are published
The City of London publishes consolidated drinking-water quality information and annual reports for its municipal systems; these reports summarise regulatory sampling and compliance testing for treated drinking water.[1]
- Annual drinking-water reports and system summaries are the first place to look for municipal test data.

Private well testing and where to find results
Private well owners in London and Middlesex County arrange testing through the Middlesex-London Health Unit or accredited private laboratories; the health unit describes sample submission, test types, and how to interpret results.[2]
- Request a well-water test kit or instructions from the Middlesex-London Health Unit or use an accredited lab for additional parameters.
- Test results are returned by the testing laboratory or public-health unit and include concentrations, guideline comparisons and recommendations.
