Qualidade físico-química e microbiológica de água potável na Província do Huambo (Angola): Água tratada do sistema de abastecimento público e água não tratada de fontes alternativas.

Water is one of the most important resources for the subsistence of life on earth, although it is also one of the main vehicles for the transmission of diseases, which has driven an increased effort on the part of the responsible entities, to make it available, with the best possible quality for the consumption of the entire human population on earth. The present study aimed to assess the physical-chemical and microbiological quality of the water consumed by the population of the city of Huambo. Samples were taken at 2 points, where two were stored at room temperature and another in refrigerated conditions. Eight samples were taken from the public supply system network (taps) and eight from deep wells (cacimbas). The harvest took place on September 24 and 25, 2013 and January 8, 2014, and 15 physical-chemical and four microbiological parameters were analyzed. Of the two points analyzed, they exceeded the recommendations of the Nº of colonies at 22ºC and 37ºC, presenting values ​​of 40.0% and 21.9% (wells) and 25.7% and 19.1 % (taps) that are not in agreement with Decree-Law No. 306/2007 of 27 August, which provides for the control and surveillance procedures for the quality of water for human consumption and its standard of potability. The E. coli analysis was absent in all analyzed samples. It was concluded that the observed microbiological contamination reinforces the need for constant monitoring of the microbiological quality of the water, aiming at the adequate potability standards for human consumption and then, preventing possible diseases.
