The pollution problems in the Great Lakes have traditionally been linked to discharges of phosphates, Mercury, chlorinated organics, organic materials like phenols and dissolved solids. The phosphates were removed by the reformulation of detergents, the mercury by th elimination of this compound at chloralkali plants, the chlorinated organics by product reformation and tighter controls at manufacturing plants, organic materials by improved treatment and the dissolved solids by improved treatment and use controls. Oil spills although an ongoing issue are generally a surface phenomenon which care controllable.
Some organic problems due to invasive species such as sea lampreys and zebra mussels are being tackled by biocides.
In genral the water quality is greatly improved since the mid-1969s.

Answer:
The levels of the pollution in the Great Lakes is under intense study by the IJC (International Joint Commission)
They indicate that there are several sources of pollution still existing in the Great Lakes system. This is due to the high population, intense industrialization, and intense agricultural activities in the region.
Since the formation of the IJC and regional water regulatory groups many significant pollution problems a have been resolved including the disposal of phosphates causing eutrophication, pollution with methyl mercury, and the uncontrolled release of sanitary sewage. There has also been work done to control invasive species (Lamprey Eels, Zebra Mussels) and discourages from commercial vessels.

You still ought to think twice about eating fish from the lakes, but the Earth is amazingly resilient if we give it a chance to heal the damage done.
