Water is essential to life, necessary for all human activities, and it must have good quality for the beverage and food preparation. However, the water used in rural areas is from wells groundwater that may have its quality affected by agricultural activities and poor sanitation. The aim of this study was to evaluate the water quality of a rural school used to house indigenous students in the region and it was done through physical, chemical and microbiological variables: pH, electrical conductivity, turbidity, dissolved oxygen, B.O.D. (biochemical oxygen demand), total solids, nitrate, phosphate, sodium, potassium, chloride, hardness, calcium, magnesium, and bicarbonate; total and fecal coliforms. These variables were evaluated for four months at two collection points: a well and a tap. The results of both showed that there are contaminations in the water by total and fecal coliforms; in addition, the physicochemical variables are outside the established standards by government Consolidation Order nº 5, September 28, 2017 of the Ministry of Health. The study demonstrates the importance of monitoring water quality as an indicator of sources of transmission of water diseases, emphasizing the importance of maintaining the monitoring of the studied variables and hygiene routines, in order to offer adequate conditions to students.
