The water quality advisory has been lifted effective July 5, 2021.
Note – this water quality advisory applies throughout Whistler, with the exception of the Emerald Estates and Cheakamus Crossing neighbourhoods.
Why is a Water Quality Advisory being issued?
Due to the current heat wave 21 Mile Creek, Whistler’s biggest water source has been off-line as heavy snow melt has created turbidity (cloudy water) conditions over the normal shut-off criteria of 1 NTU. With this major water source off-line during the high water demand situation created by the heat wave, Whistler’s water fire storage levels have been compromised. In order to recover adequate reservoir levels the RMOW will be operating the 21 Mile Creek Intake at turbidity levels of up to 2.0 NTU. The water quality is closely monitored on an ongoing basis by the RMOW and the chlorination and UV disinfection systems are fully operational, therefore the risk is low. However, some customers are being advised to take extra precautions until turbidity levels return to below the normal 1.0 NTU criteria.
What does a Water Quality Advisory mean?
A Water Quality Advisory means the risk is low, and only some customers are advised take extra precautions when ingesting the water.
Who should take extra precautions?
Individuals with very weak immune systems are advised to take extra precautions.
What should these customers do?
For these customers, water intended for the following uses should be brought to a full boil:
- washing fruits and vegetables
- making beverages or ice
- brushing teeth
Alternatively, water may be obtained from another source which has been fully treated (e.g. commercially bottled water).
