Increased Testing of Michigan’s Waterways

A new analysis gives us a better idea how much human and animal waste is ending up in the state's waterways. Research done by the "Michigan Department of Environmental Quality" finds over 7,000 miles are affected. When compared to the last several years that comes out to a considerable increase. However the experts say the reason for this: water testing is being done more often. The study found when the Great Lakes, inland lakes and rivers are taken into account water quality in Michigan scores good to excellent. However officials say mercury and PCB contamination are still big concerns. Also efforts are ongoing to control problems related to things like overflowing sewers and leaking septic tanks.
