The City of Marshfield is investigating a spill that sent contaminated water into Mill Creek. The city said it was notified on Wednesday, Nov. 11, about a spill of an unknown substance from an unknown source or location.
The substance was released from the city's storm sewer system at its outfall to Mill Creek within Wildwood Park. The city said an unknown volume of contaminated water reached the surface waters of the creek.
The drainage area for that outfall includes downtown Marshfield, south of the CN railroad tracks. That area helps define where the substance could have entered the system, though its origin has not been identified.
City staff are continuing to monitor the situation. The city said it is working closely with the Wisconsin Department of Natural Resources on the release.
Because the source and nature of the spill are still unknown, the city is asking anyone with information about where it originated, what was spilled, how it happened or who is responsible to contact the Marshfield Public Works Department at (715) 486-2034.
