Water quality is one of the most discussed topics around the world, it is an
indispensable resource. Excessive anthropogenic processes modify the quality and
standard of water, whether surface or underground, intended for human supply. In view
of the above, the present work aimed to evaluate the quality of water in artesian wells
in the district of Santo Antônio do Matupi, in Manicoré–AM. Six points were selected in
different regions of the district during the rainy season. Using these samples, the
physical-chemical and microbiological parameters were evaluated. The data were
compared with Ordinance GM/MS No. 888, of May 4, 2021. The variables analyzed
were Thermotolerant Coliforms, Total Coliforms, Total Dissolved Solids, Turbidity,
Apparent Color, Total Iron, Total Manganese, pH, Conductivity and Temperature. The
variables total phosphorus and total dissolved solids presented values within those
permitted by legislation. On the other hand, the pH values indicated that almost all
points collected, except P6, do not comply with current legislation. For total
manganese, only sampling point P6 is above the limit recommended by the ordinance.
Therefore, it is worth highlighting that, of the six points sampled, five indicated the
presence of Total Coliforms. The presence of these pathogens in most of the locations
studied indicates that the water is unfit for human consumption and does not meet
potability standards. The assessment emphasizes the importance of continuous
monitoring of water quality in the district, implementing corrective and preventive
actions to ensure compliance with Brazilian regulations for water supply.
