Water Quality Advisory Issued for Telkwa Community Water System

Starting from 7:00pm on Tuesday, September 28, 2021, the Village of Telkwa water system is under a Water Quality Advisory. Northern Health and the Village of Telkwa recommend that children, pregnant women, the elderly, and persons with weakened immune systems drink bottled water at this time.

All owners of public premises must make patrons aware of this Water Quality Advisory.

It is important that residents practice water conservation for the duration of this advisory. More information on water conservation can be found on our Water Use page.

A Water Quality Advisory is being issued for all users of the Telkwa Community Water System. The Village is conducting planned upgrades to the Water Treatment Plant’s ultraviolet disinfection system. While the system is being upgraded the treatment plant will be non-operational, and the system will be supplied by stored treated water. Once the work is completed, a Water Quality Advisory is required until bacteriological testing confirms that the new ultraviolet disinfection system is operating properly. Upon restarting the Water Treatment Plant, the Village may use the groundwater well to supplement the Water Treatment Plant and help refill the water reservoirs. The water from the groundwater well exceeds the maximum acceptable concentration (MAC) of 0.12 mg/L for manganese as established in Health Canada’s Guidelines for Canadian Drinking Water Quality. Residents may experience a change in the water clarity and taste during this time due to the raised levels of manganese.

Infants and young children are the most sensitive and vulnerable population, as their bodies absorb more manganese and cannot regulate or remove the chemical as readily as adults and older children. As a result, the drinking water must not be used to prepare formula for bottle-fed infants. An alternate source of safe drinking water, such as bottled water, must be used when preparing formula for infants and young children.

Breastfed infants are generally considered at lower risk to manganese exposure as the transfer of manganese to breast milk is limited. Pregnant or breastfeeding women who have concerns may wish to use a safe, alternate source of drinking water or consult with a healthcare professional.

Water exceeding the MAC for manganese can be used for cooking and drinking by non-vulnerable groups and is still considered safe for hand washing, bathing and showering.

More information regarding manganese in drinking water can be found on the HealthLinkBC website:


This advisory remains in effect until another public notice is issued upon request or order of a Drinking Water Officer advising that the advisory has been amended or may be rescinded. The Village is working with Northern Health on this matter.




A Water Quality Advisory is one of three types of public notices commonly used by Drinking Water Officers (Water Quality Advisory, Boil Water Notice, and Do Not Use Water Notice). The decision whether to request or order issuance of one of these notices rests with the discretion of the Drinking Water Officer. A Water Quality Advisory is used in situations in which the public health threat posed by the water system is modest and actions can be taken to reduce the risks through means other than requiring a Boil Water Notice or Do Not Use Water Notice.
