The Kansas Department of Health and Environment said Friday that dangerous levels of bacteria have been detected in the Arkansas River, and the agency is advising people to have no contact with river water between the Lincoln Street Dam in Wichita and the Oklahoma state line.
Residents also are being asked to make sure that pets and livestock are kept away from the water.
A KDHE news release said the high bacteria levels were detected during a routine sampling of river water.
Agency spokeswoman Miranda Steele said KDHE officials have confirmed that a fish kill occurred in the river, but she said didn’t know the exact location or size of the kill. A black foul-smelling substance was observed near the site of the kill, she said.
KDHE officials are trying to identify the source of the contamination, she said.
