Kewaunee County residents received an update on the safety of their groundwater Tuesday morning at the Land and Water Conservation Committee meeting. Dr. Mark Borchardt, a microbiologist with the U.S. Department of Agriculture, shared findings of groundwater contamination in the area. Kewaunee County Chair Bob Weidner says the new sample findings from the well testing is concerning.
Borchardt’s study showed a relationship between the distance of wells to manure pits and septic system drain fields and how that could possibly infect wells with dangerous pathogens. Weidner says the extensive study of wells in Kewaunee County showed the majority of contamination came from agricultural run-off along with some significant amounts of human waste in the groundwater.
