(KNZA)--The Kansas Department of Health and Environment has issued a boil water advisory for Jefferson County Rural Water District #7 in Jefferson County.

KDHE issued the advisory Wednesday due to the loss of pressure in the system.  Failure to maintain adequate pressure may result in a loss of chlorine residuals and bacterial contamination.

KDHE says customers should boil the water they use for drinking or food preparation for one minute prior to use or use bottled water.

The advisory will remain in effect until further notice.
