ANÁLISE DA QUALIDADE DA ÁGUA EM UMA ESCOLA PÚBLICA NA CIDADE DE MORRINHOS - GO

Abstract

Public health issues need to be investigated as well as the quality standards for potable water, which is directly associated with them. In this way, the aim of this work was the physical, chemical and microbiological analyzes of tap water consumed by a public community school located in the city of Morrinhos-GO. The parameters examined were the water turbidity level, pH and fecal contaminations. A total of 15 water samples were collected between January and February of 2016 at 05 strategic points of the school area to ensure that the collected samples are representative of water quality throughout the distribution system. After the analysis were carried out, the data obtained were compared with the national water quality guidelines established by the ministry of health (ordinance No. 2,914, of December 12, 2011). In the result of the physical chemical analysis the values found were pH ranging from 6.27 to 7.18, turbidity ranged from 0.35 to 0.76 NTU, free residual chlorine ranged from 0.37 to 0.8mg.L-1 , apparent color ranged from 4.5 to 14.2 uH and Fluoride content ranged from 0.55 to 0.69 mg.L-1. And the total coliform and fecal coliforms testing for the 15-water sample were negative. The results obtained in this study, and considering both random and systematic variations in water quality, suggested that the quality of water based on the analyzed parameters is such that it is suitable for consumption purposes.
