The purpose of this study was to identify the occurrences of the the three causative agents, geosmin, 2-MIB, β-cyclocitral and quantitate the metabolites from the beginning of agal bloom to their end, and figure out a relationship between the numbers of actinomycetes or Microcystis aeruginosa and geosmin, 2-MIB, β-cyclocitral in Reservoir Hapchon. M. aeruginosa was dominated during the algal bloom from June to August and correlated significantly with the quantities of β-cyclocitral(r=0.91), while the population densities of actinomycetes was not correlated significantly(r=0.49) at the same time. Consequently, M. aeruginosa which produced large quantities of β-cyclocitral was responsible for the odor and taste problem in Reservoir Hapchon.
