Análise da potabilidade da água de chafarizes em cinco bairros do município de Pedro II-PI

Abstract

With water scarcity, some regions of Brazil, especially the Northeast, need alternative and effective means for their water consumption, one of the alternatives found by the population are the fountains. This type of water source is very common in several places, however, they do not usually go through appropriate treatments. In this circumstance, this research aimed to analyze the water quality of some neighborhood fountains of Cristo Rei, Mutirão, Vila Kolping, Boa esperança e do Centro, located in the city of Pedro II-PI. For that, was made the analysis of the physical-chemical and microbiological parameters of 10 samples collected from the 5 collection points (fountains), two samples at each point, one from each parameter. The physical-chemical parameters analyzed were: pH, turbidity, alkalinity, hardness, chloride and conductivity. In the analyzes microbiological tests were used to determine Escherichia coli and Coliformes totais. All results were compared with the standards established by the Portaria Nº 2.914 de 12 de março de 2011 do Ministério da Saúde, reveal that in all the samples the pH is below from the established standard, causing an acidity in the water, which at exaggerated levels, can be harmful to the consumer, however, in the bacteriological samples, no type of contamination was found, either the Escherichia coli or Coliformes totais. The samples are all within the standards required by the Portaria nº 2.914 de 12/12/2011.
