Divers are planning to collect zebra and quagga mussels this week in Muskegon. It’s part of a national effort to study chemical pollution, called Mussel Watch.

The mussels are invasive species, but they’re also good study subjects.

Ed Johnson is a senior scientist with the National Oceanic and Atmospheric Administration. He says zebra and quagga mussels are ideal for studying contaminants in the Great Lakes, because they stay in one place; they don’t move around like fish or birds do.
