Clean-up is currently underway at the scene of a manure spill in Kewaunee County.  The Wisconsin Department of Natural Resources is currently assessing the impact of the spill on County Highway J near Highway 42 on property owned by the Wakker Farm.  A DNR news release says the spill was reported on Monday and Wakker Farm employees are involved in clean-up efforts. The manure runoff spread to a ditch that leads up to Sandy Creek.  The DNR is advising nearby residents to monitor their well water for changes in taste, smell and color.  Those who notice any changes should switch to an alternate water source and contact the DNR for help.
