Following reports from concerned citizens about a smell near an unnamed creek east of Redfield, officials with the Iowa DNR say they’re investigating a discharge to the creek. DNR staff found material seeping from an old tile line to the creek, which was creating a milk grey color in the creek and the odor. Authorities say it appears the discharge has been ongoing since July, based on comments from citizens.

The discoloration and odors exist along the creek until its confluence with the South Raccoon River. No impacts have been observed in the river. DNR staff are currently working to identify the source of the discharge. Nearby public water supplies have been notified. People and pets should avoid contact with water in the creek
