Abstract

The assessment of water quality destined to population consumption is something essential; for this reason the physical, chemical and bacteriological parameters are monitored and must be according to the limits established in legislation. Thus, the present study has determined and compared the application of two Water Quality Indexes (WQI) of 249 treated water samples, collected in the water supply system of the city of Goiania, during a period of 24 months. These samples were subjected to analysis of 10 physical-chemical parameters and 3 microbiological parameters. The WQI values for the samples were determined using a Canadian WQI calculation model, and also by using different calculation model, employed by the local State Company. The results indicated that the water distributed in 88.8% of the samples were rated as excellent by the two models, indicating that the model employed by local State Company is more restrictive than the Canadian model, besides that there is a seasonal influences pointing to a worse water classification in the rainy season. Keywords: WQI, Water quality, Canadian model.
