There is a boil water order in effect for people located after and including 537 Green Head Road in the West Side after bacteria was found in the water.
It is safe for people to take showers, bathe and use swimming pools.
It is also safe to wash dishes in hot water or in a dishwasher.
Saint John Water is working with the Department of health to fix the problem but the boil order is expected to last at least until the end of the week.
