Violations:
A summary of the violations found during the inspection are listed below.
| Code | Description / Observation / Corrective Action |
| 313 | Inadequate treatment Observation: Levels of trihalomethanes (THMs) and haloacetic acids (HAAs) in the water exceed the maximum acceptable concentrations given in Health Canada's Guidelines for Canadian Drinking Water Quality. The water supplier has been measuring the levels of THMs and HAAs every three months. Corrective Action: The water supplier will need to continue to measure the levels of THMs and HAAs every three months. As the running annual average of quarterly samples shows that the levels of THMs and HAAs exceed maximum acceptable concentrations, the water supplier will need to continue to make these results publically available, as well as providing users with information on how they can reduce their exposure to THMs and HAAs. In the long-term, the implementation of effective water treatment will ultimately address the elevated THM and HAA levels. The water supplier will need to continue to measure the levels of THMs and HAAs every three months. |
| 313 | Inadequate treatment Observation: Provincial surface water treatment objectives are not being met. The present water treatment cannot achieve 3-log inactivation of Cryptosporidium (although disinfection to inactivate Giardia is being preformed). Also, there is currently only one treatment process (chlorination) and surface water sources require two independent treatment processes. Monitoring data also shows that turbidity sometimes exceeds the objective of one nephelometric turbidity unity (NTU) or less. During the last 12 months (August 2022- August 2023), 2 water quality advisories and 2 boil water notice have been issued because of distribution system integrity failure, inadequate disinfection residual in the distribution system. Operating permit timeline conditions for the mandatory submission of the construction permit application will be revised to January 2028 due to reprioritization of the water system work onto repairs and replacement of the distribution system infrastructure. This permit condition extension is granted under the expectation that the City of Prince Rupert will provide annual updates on the completed and in-process work on the water system. Corrective Action: The water supplier must continue to monitor the source water for Giardia and Cryptosporidium, design and implement effective water treatment that meets provincial surface water treatment objectives, and provide updates on the working done as per the frequencies and timelines specified in the operating permit conditions. |
