All residents and businesses in Happy Valley-Goose Bay who use Spring Gulch Water are under a boil-water advisory.
The town issued the urgent warning Saturday evening.
The statement, which appeared on the town’s website and Facebook page states: 5 Wing Goose Bay advises that heavy thunderstorms in the Lake Melville area caused flooding which in turn caused excess surface water from the sandy soil around Spring Gulch to flow into the water supply.
Residents are advised to bring water that you might ingest to a rigorous rolling boil for one minute.
For example, boil water used for drinking, brushing teeth, making juice from concentrate and powders and cooking.
Water to be used for washing fruits and vegetables, making infant formula and cereals, and making tea, coffee and other hot drinks should also be boiled.
The boil-water advisory will remain in effect until further notice.
The public will be notified once it is lifted, the town stated.
