COLDSTREAM (Greater Vernon Water)– WQA was in effect May 19 to 21.
KAMLOOPS Municipal Water System – All water advisories issued for east Kamloops neighbourhoods in the wake of a broken water main have now been rescinded as of May 21st.
The City of Kamloops has attributed the delay in lifting the DNC advisory in the Barnhartvale’s Area to processing time to complete water quality testing; the Area is in close proximity to agricultural and industrial areas and testing in locations under a ‘do not consume’ advisory, due to the possibility of contaminates from these land uses, is more specialized and rigorous, and fewer service providers are equipped to perform this type of analysis, which contributes to longer processing times.

With the water lines turned off over the winter, there is potential for contaminants to accumulate; When the water is turned back on in the spring, the lines are flushed and disinfected to ensure potability of the water supply. The water quality test results can take several days after the water is turned on.
When water lines are depressurized, sedimentation may occur within the lines. Following the restoration of water service, residents should run taps for at least 5 minutes to clear any discoloration, particles or excess chlorine from their water lines.
Waterlines should be flushed again by residents for 5 minutes after the BWA has been lifted in their area.
