The decrease of the water available for human consumption is directly related to the unregulated and unconscious action from the man himself. In rural areas, this depreciation is related to inappropriate conditions of artesian wells that capture the water (old wells and poorly sealed) and which are usually close to sources of pollution, such as septic tanks and animal grazing. In this context, the objective of the present work was to evaluate the physico-chemical and microbiological quality of underground water samples made available for consumption in three schools in the field next to the municipality of Uberlândia-MG. Methodologically, the data were statistically processed by means of descriptive and multivariate analysis (Pearson correlation coefficient). All schools are supplied by an artesian well, being carried out simplified treatment (chlorination mechanism of chemical treatment). In only one of the schools was identified the presence of a septic tank sewage collection system. Of samples evaluated, all were at odds with the standards laid down in annex XX of the Consolidation Ordinance No. 5 of the Ministry of health (old law 2,914/2011) in at least one of the parameters evaluated. Therefore, the results reflect the possibility of biological contamination of the water by grazing areas located in the region close to the wells, as well as the need for emerging measures, such as regular cleaning and maintenance of storage systems and distribution of the water consumed in the institutions.
