The town of Denton says that, in accordance with guidelines established by the Montana Department of Environmental Quality, the "boil water advisory" order will stay in effect until Monday, May 18.
At that point, DEQ will reassess the situation. This is a standard timeline set to assure safety of drinking water.
Justin Robicheau talks with the mayor and residents about the situation:
According to Mayor Stephenie Stolle, Denton Foods and Big Spring Water of Lewistown came to the rescue, providing clean drinking water for the community.
She said, "They came in after hours with a truckload for us, and we've been trying to provide here out of the town hall. And before they got here, our local grocery store worked with us on making sure everybody had water."
Town officials say the disinfection device has been repaired and workers will continue to monitor and test the water supply to evaluate potential contamination. The town is also continuing to provide at no charge one gallon of water per day per person.
(1st REPORT, MAY 12) The town of Denton is under a "boil water advisory" as of Monday, May 11, 2026. This is a boil advisory, not a boil order.
Civic leaders said in a news release that there was a "disinfection failure" at the water treatment facility on May 10th.
Due to the inability of the system to provide the minimum amount of treatment required, the quality of water can not be assured at this time.
As a precaution, the town is advising people to boil water before drinking or consuming it.
People are advised to not drink town water unless it has been boiled. They recommend bringing the water to a boil, letting it boil for one minute, and then let it cool before using.
The advisory states that boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice.
On Tuesday afternoon, civic leaders said that Big Spring Water is bringing a delivery of one-gallon jugs to the town hall later in the afternoon/evening.
The town will provide one gallon per person per day until this is resolved.
They advise people to check availability at the grocery store if you are in immediate need.
