The province's chief medical officer of health issued an alert on Friday for the town of Alma.
The alert says it's necessary that people boil all water for drinking and cooking purposes because of high turbidity levels in the water.
While drinking the water can make you sick, the alert says it can be used for bathing purposes.
Excessive rainfall forced multiple boil advisories for the neighbouring town of Riverside-Albert last summer.
The community must have three days of clean water samples before the advisory is lifted.
