Abstract

The consumption obtained from alternative sources water, especially in shallow dug wells, has grown tremendously due to shortage of good quality water in surface waters. The guarantee of human water consumption, using appropriate potability standards is a matter relevant to public health in Brazil, Ordinance No. 2914 of 12 December 2011, the Ministry of Health defines the maximum permissible values for the bacteriological characteristics, organoleptic, physical and chemical drinking water. Thus, the present study examined the water quality in shallow wells and storage tanks private waters in six townhouses in conjunction FAIR VI, the fair city of Santana (BA) using microbiological tests to assess the most likely number of Total Coliforms and thermotolerant coliforms, which characterize the quality of the feature. a comparison of water quality in homes with the presence of domestic animals with those who do not have to assess if you have any influence in the same environment in which they live, identifying the main uses of these waters was made. From the analysis it was concluded that the three houses containing animals, two are at odds with what advocates concierge current drinkability in Brazil, the same was observed in water tanks which showed the presence of coliform bacteria in the two sampling, so that their use for noble purposes, may result in risks to human health the survey also revealed that groundwater is used for human consumption and that most users opted for this solution motivated by dissatisfaction with the services provided the concessionaire of the public supply system.
