A downwelling event occurred during the period of elevated geosmin concentration in the intake waters of water treatment plants. The event was characterized by elevated water temperatures, onshore and cyclonic alongshore circulation. The downwelling was relatively poorly developed off Cobourg where the geosmin concentration was the least elevated. The downwelling event was stronger off Mississauga and Grimsby, where the geosmin concentrations were higher. The flow regime supports the hypothesis that the elevated geosmin concentrations originated in the warm offshore waters driven inshore and alongshore during a downwelling event. The same conclusion was reached in a field study conducted in 2000 and reported by Rao et al. (2003)"--Abstract.
