Pathogen pollution in Michigan’s lakes and rivers – caused by human and animal waste draining into surface waters – is far more widespread than previously documented, according to new state data.
The identification of rivers impaired by potentially harmful pathogens has more than doubled in recent years – from 3,359 miles in 2008 to 7,232 miles in 2012, according to a draft of the Michigan Department of Environmental Quality’s 2014 impaired waters report obtained by Bridge.
Kevin Goodwin, a DEQ senior aquatic biologist, attributed the increase in pathogen pollution to local and state agencies testing more rivers for fecal matter.
