Qualidade da Água Potável de Cidades do Noroeste do Paraná.

Abstract

The present work has the finality to avalue the physical-chemical and microbiological quality of the potable water of 4 cities in thestate of Parana, Brazil, since any alterations in the quality of this resource may cause losses on many ends which water is used for. The metodology presente on Standard Methods for the Examination of Water and Wastewater together within the Ordinance nº 2.914 of the Health Ministry were the basis for the analysis of the water in this research. determination of alkalinity, hardness, chloride, free CO2 and nitrate, as well as total coliforms, were the indices evaluated, all in triplicate, for the determination of water quality. The obtained results was satisfactory, where in all physical-chemical analyzes, the samples presented within the recommended limit. Already in the microbiological analyzes, all the samples presented themselves containing total coliforms at least in one concentration. Then concludes that the samples of water, have a certain nonconformity within the potability standard, being a possible contamination generated at some point in the treatment process in the water treatment stations.
