Abstract: In recent decades, there has been an increase in the demand for drinking water worldwide, particularly intensifying the use of groundwater. This naturally potable water reduces the cost of collection and treatment. However, anthropogenic activity has significantly polluted these sources. Given the problem of aquifer pollution, this study aimed to assess parameters that may indicate changes in the quality of the groundwater supplied to the Federal Institute of Education, Science, and Technology of Maranhão (IFMA), Timon Campus. Microbiological parameters (total coliforms and E. coli) were analyzed using the Colilert Enzymatic Chromogenic Substrate technique, and the physicochemical parameter (free residual chlorine concentration) was analyzed using the DPD colorimetric method. The aim was to verify the compliance of the water consumed by the school community with the standards established by Ordinance GM/MS No. 888/2021 of the Ministry of Health (MS). The results of the samples collected from the tubular well, the water tank and the drinking fountains that supply the school showed total coliforms. However, after installing an automatic chlorine dispenser, the samples collected from the water tank and drinking fountains showed results that meet the MS potability standards analyzed in this study, ensuring water free of pathogenic microorganisms, making it suitable for human consumption, thus avoiding risks to the health of users.
