5203 |a"Taste and odour events occurred in western Lake Ontario drinking water in two successive years following the decay of beached masses of cladophora, a filamentous green alga. Geosmin was identified as the compound imparting a taste and odour to the Burlington drinking water. Geosmin has been reported to be produced by actinomycetes bacteria or blue-green algae when growing in eutrophic conditions. Evidence suggests that the geosmin was not generated in the littoral zone of Lake Ontario but was generated inside the Water Treatment Plant. Geosmin was resistant to chlorination. The decomposition of Cladophora in the littoral zone surrounding the water intake was felt to supply organic carbon for actinomycetes growth. Anaerobic decomposition of cladophora produced several sulphur compounds responsible for odour problems in the Spencer Smith Park area"--Abstract.
