OLPE (KSNT) – The Kansas Department of Health and Environment (KDHE) has issued a boil water advisory in Lyon County last week. The KDHE said customers of the City of Olpe public water supply in Lyon County were placed under a water boil advisory after KDHE officials found the system at risk of bacterial contamination. The advisory comes after a waterline break. The KDHE said the waterline break can result in a loss of chlorine residuals and bacterial contamination. The advisory went into effect on Oct. 25 and will be in effect until the KDHE rescinds the advisory.

Supervision of children is necessary while bathing so that water is not ingested. Persons with cuts or severe rashes may wish to consult their physicians.  For more local news, click here.
