(KNZA)--A boil water advisory has been issued for the Jefferson County community of Ozawkie.

The Kansas Department of Health and Environment issued the advisory Monday  because the water system is unable to maintain required chlorine residual levels. Failure to maintain adequate chlorine residuals may lead to bacterial contamination.   

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

The advisory will remain in effect until further notice.
