The Regional District of Kitimat Stikine says its taking a precautionary approach after bacteria was discovered in the Thornhill Community Water System.
District officials issued a boil water notice Tuesday night for all communities connected to the system after total coliform bacteria was revealed in test results.
Works and Services Manager Roger Tooms says total coliform bacteria is not likely to cause illness, but their presence indicates that a water supply may be vulnerable to more harmful microorganisms.
Toombs says says water supply and civil engineering consultants are examining the cause of the bacteria while district staff disinfect water storage facilities and flush the distribution system.
The Thornhill Water Supply comes from two deep groundwater wells which are tested frequently. Tooms says those tests have revealed no indication of total coliform in the wells.
The regional district is asking businesses and residents to be patient and use caution while consuming Thornhill water for the time being.
