How can it be non-detect if I smell petroleum hydrocarbons?

The human sense of smell detects the presence of petroleum hydrocarbons at a much lower concentrations than the human sense of taste and well before any technology capable of testing for petroleum hydrocarbons and well before any significant levels that would cause impacts to health. This means that the human sense of smell can detect the presence of petroleum hydrocarbons at a much lower concentration than what Health Canada deems as acceptable in the Canadian Guidelines for Drinking Water Quality. 

Since October 23rd, 2021, all samples undertaken by the City for petroleum hydrocarbons have returned resutls at or below detection levels of concentration. As such, the drinking water from the Water Treatment Plant continues to meet or be better than the Canadian Guidelines for Drinking Water Quality and territorial requirements.

However, if there are concerns or if you take the necessary flushing measures and still smell fuel, please call the hotline and report it.
