Odour Concentration

Abstract During August, 1983 geosmin was identified in a municipal water supply drawn from western Lake Ontario. The geosmin concentrations were 0.01-0.07 μg L-1, within the range for threshold odour concentration of 0.01-0.2 μg L-1. 2-Methylisoborneol was not detected. The odour 'event' coincided with a dieoff of Cladophora in the lake, but we were not able to establish a direct link between the dieoff and geosmin production. Decomposing Cladophora in shoreline areas produced a strong odour in the air. 3-Methylindole, elemental sulfur, dimethyl tetrasulfide, and dimethyl pentasulfide were tentatively identified in water samples collected from these areas, but geosmin and 2-methylisoborneol were not detected.

Comprehensive Study

Some forms of organic matter existing in the water have direct or indirect effects on microbial growth. By the investigation data over drinking water and reclaimed water, we summarized organic limiting factors that may affect the growth of microorganisms and factors affecting these water qualities in the reclaimed water supply network, such as a variety of treatment process and the residual disinfectants. Through its comprehensive study, we want to make a contribution of opinion to control the growth of microorganisms in reclaimed water supply network.
