NOAA taps invasive mussels to track Great Lakes pollution

Zebra and quagga mussels have threatened Great Lakes ecosystems since they arrived in the 1980s. Now the invasive species are acting as unlikely allies in identifying pollution hotspots. The National Oceanic and Atmospheric Administration’s Mussel Watch program is collecting the mollusks at sites across the Great Lakes to measure the concentration of harmful pollutants in their tissue. A report with the results, expected this fall, will serve as an indicator to communities that they may be in need of cleanup, said one of the program’s leaders. Mussel Watch started along the Atlantic coast in 1986 and is the “longest running continuous contaminant-monitoring program of its kind in the United States,” according to NOAA.
