Schools are closed in Litchfield on Monday because the city is under a boil water advisory. 

The city issued the boil water advisory for the nearly 7,000 people who live in the city after it experienced a "loss in pressure" late Sunday evening (this is one of many incidents that can trigger a boil water advisory). 

This advisory means people shouldn't drink water without first boiling it for 3 minutes and then letting it cool, the city says. 

People should do this for all water that's used for drinking, brushing your teeth, washing dishes, and preparing food until the city lifts the order, the Minnesota Department of Health's website says. 

Boiling the water will kill bacteria and other organisms that may be in the water. 

The city is currently testing the water for any bacteria, and will let people know when the advisory has been lifted.
