The village of Freelton is under a precautionary boil water advisory.

Public Health Services issued an advisory Wednesday night for residents to boil their water. Officials are also calling residents and distributing yellow boil water advisory notices door to door for all homes and businesses connected to the Freelton municipal drinking water system.

A recent lab test result indicated bacterial contamination in the water sample collected from the Freelton water tower on May 27.

Hamilton Water will do more sampling and testing over the next 24 to 48 hours to make sure the water is safe. If follow-up samples and test show the water is free of bacteria, the advisory will likely be lifted Friday afternoon or evening.

“We want to caution people that although there have not been any reports of illness from the Freelton municipal water supply, they need to boil their water for one full minute before drinking or using it for activities when water could be swallowed,” said Dr. Hamidah Meghani, Hamilton’s associate medical officer of health.

“The elderly, the very young and those with weakened immune systems have the most potential risk, but we are asking everyone to be careful until we are satisfied that the advisory can be lifted.”
