A public health advisory has been issued by the Grand Traverse County Health Department after approximately 200 gallons of biosolids (a waste product from the sewage treatment process) were released from the Traverse City Regional Sewage Treatment Facility into the north end of Boardman Lake.
The Grand Traverse County Health Department released that Clinch Park as well as Bryant Park are at a Level 4 water quality index which means no body contact with the water is advised. A level two water quality index for Acme Bayside Park means no contact above the waist is advised.
According to the Health Department, the release took place late Wednesday afternoon. They say biosolids are considered safe for application to non-food agriculture, but the Health Department is advising the public against any body contact of the waters in the North end of Boardman Lake, Lower Boardman River from the Sewage Treatment Facility to the mouth of Grand Traverse Bay, and the beach areas from Clinch Park to Bryant Park.
The Michigan Department of Environmental Quality has been contacted and will be working with public health officials and officials from the regional sewage treatment facility to ensure that the necessary corrections are made.
Testing of the affected waters will begin on Thursday and will continue until these waters return to normal.
The Health Department says the drinking water supply for Traverse City is not affected since the city's drinking water comes from East Grand Traverse Bay.
