Door to Door Water Testing

The City of St. Thomas has been made aware that homeowners have been approached and asked to provide water samples for analysis. In some cases, the person asking for the sample has indicated that they are “from the City of St. Thomas”. In most of these cases, the person asking for the sample is not a City of St. Thomas employee, but is representing a private company that sells home water treatment equipment. These companies use a variety of methods to convince homeowners to purchase expensive home water treatment systems.  

The drinking water provided by the City of St. Thomas has been treated to surpass the quality standards set by the province of Ontario, and the results of our rigorous testing are available on our website.  the City of St. Thomas advises that homeowners use discretion if presented with information indicated that their tap water requires additional treatment.  Homeowners should also be cautious of salespersons that pressure them into signing contracts right away, or advises that the price being offered is only available for a limited time.


  • No door-to-door sales people are authorized to make a health-based test on your water.
  • Door-to-door water tests do not tell you about water safety,
  • Chemical trickery may make your water look brown, just because of natural mineral content.
  • If you have concerns about water safety, contact the City of St. Thomas or  The Elgin St. Thomas Public Health Unit.
  • If you believe you may have been misled by a door-to-door salesperson, learn more about your rights under the Consumer Protection Act.

Occasionally, the City of St. Thomas staff wil contact homeowners regarding water quality issues.  In all cases, our staff will have identification to verify that they are City Employees - and on no occasion will City staff attempt to sell any product.

If you have any questions regarding St. Thomas drinking water, feel free to contact us at 519-631-1680 ext. 5121.
