Abstract — Water coming from mines to be destined for human consumption must comply with Ordinance No. 888 of May 4, 2021 of the Ministry of Health. the standard of potability of water for human consumption. The objective of this study was to evaluate, through physical-chemical and microbiological variables, the quality of mine waters that are being exposed to consumption by the population of the municipality of Caratinga-MG, using the parameters referred to by Ordinance No. 888 of 2021. The methodologies used for the analysis of physicochemical and microbiological parameters followed the protocols of the Standard Methods For the Examination of Water and Wastewater, 23rd edition. The results of the physical-chemical analyzes of all water collection points are within the potability standards required by Ordinance No. 888 of 202, and the results found referring to microbiological analyzes demonstrated that there is no contamination by fecal coliforms, and that It is an excellent index, and makes us think about applying the simple chlorination process, which can contribute to the disinfection process and maintain water quality. Consuming quality water is a right of every citizen, therefore, actions to adapt mine waters used by the population for consumption, or any other sources, are essential, and therefore, it is recommended to continue monitoring water quality of the mines studied in the municipality of Caratinga-MG. I. INTRODUCTION The water mine is formed when the aquifer, that is, the subterranean sheet reaches the surface and, thus, the water stored underground surfaces on the surface of the land, and is popularly known as spring, mine, water hole, headboard, spout or fountain. Water from mines to be destined for human consumption must comply with Ordinance No. 888 of 2021 of the Ministry of Health. This ordinance describes all the physical-chemical and microbiological parameters necessary for the standard of potability and human consumption, being o except applied only in mineral water source, natural or water added with salts intended for consumption after bottling, which are subject to the microbiological guidelines of Resolution (RDC) No. 274 of 2005 (BRASIL, 2005). The characteristics found in groundwater are due to physical, chemical and biological processes that determine a wide variety of substances present in the water, and can also be affected by anthropogenic activities, such as domestic and industrial polluting loads, which can also influence the quality of water underground. Normally groundwater is less prone to contamination, because, during the path in which water percolates between the pores of the subsoil and rocks, it is purified through a series of physicochemical and bacteriological processes, which naturally modify the characteristics of the water, making it more suitable for
