BAYFIELD, Colo. -- Bayfield residents were still boiling their water Friday, after officials put a boil order into effect Thursday.

The Bayfield Marshall's office issued the order, after water treatment officials identified a problem with a water filter. Mud and ash flows have contaminated the water supply.

Crews went door-to-door in Bayfield Thursday night telling residents to boil their water for at least 10 minutes before drinking it.

Officials said that it takes at least 24 hours to restore normal water use. The restrictions went in place at 5 p.m. Thursday.

The boil order has affected Bayfield schools. All schools were closed Friday. The Pine River Early Learning Center was also closed.

The Southern Ute Indian Tribe has assigned a 3,600-gallon water truck to help the town cope with its water crisis, the town manager said Friday morning.

The truck was statiooned at the town shop, where people can normally buy water to fill cisterns. Bottled water was also available for residents.
