Abstract

This study was conducted to evaluate microbiological quality of two important
surface water from Meia Ponte river and João Leite stream, which are used for
drinking purposes in Goiania city, Goias State. In addition, treated water, wastewater
and treated effluent from municipal Water and Sewage Treatment Plants were
analyzed. The study also aimed to correlate pluviometric density and the physical,
chemical, and microbiological parameters in water, by Pearson Correlation statistical
test. The coliforms concentration, Salmonella presence, and the physical and
chemical parameters were evaluated in raw and treated water, wastewater, and treated effluent samples collected in municipal Water and Sewage Treatment Facilities in 2005. According to the results obtained, Meia Ponte river was classified as Class I
and João Leite stream as Class III, during the analyzed period. Pluviometric density
was correlated to fecal contamination and some physical and chemical parameters
of water (color and turbidity) in Meia Ponte river and João Leite stream. Water
treatment was considered satisfactory; however, the primary treatment in the Sewage
Treatment Facility was not able to decrease significantly the fecal load of wastewater,
being an important source of contamination to the Meia Ponte river.
