Piloting Mussel Watch in Canada in collaboration with Fathom Five National Marine Park (FFNMP) and TRACE Lab, is exploring a range of contaminants in Lake Huron. Our research involves introducing the United States National Oceanic and Atmospheric Administration’s (NOAA) Mussel Watch Program to Canadian waters in the Great Lakes for the first time. We’ve chosen quagga and zebra mussels due to their abundance and unique suitability as contamination indicators. These mussels will be used to assess more than 150 chemical contaminants, including legacy substances like pesticides and emerging concerns like pharmaceuticals and flame retardants. The research aims to reveal the presence of environmental contaminants in the area and their potential impact on the local food web, including the fish population. FFNMP staff, with support from Peel Regional Police’s Underwater Search and Recovery Unit (USRU), have collected mussels within the park and hope to expand the program to other areas around the Saugeen (Bruce) Peninsula in the future.
