water quality, hardness, TDS, lead, arsenic


In the present research work, a study was carried out on the quality of water for human consumption, in the central region of the P'urhépecha plateau of the state of Michoacán, Mexico, monitoring the variables of hardness, TDS, temperature, pH and concentration. of As and Pb in different sampling sites and in different seasons of the year, which were compared with parameters established by the Official Mexican Standard NOM-127-SSA1-1994, NOM-250-SSA1-2014, Environmental Protection Agency of the United States of America (USEPA) and those established by the World Health Organization (WHO). The results obtained show a pH that is 7 ± 0.5, the temperature oscillates between 18 and 22 ° C, the hardness between 60 and 200 ppm, unlike a site that shows 600 ppm. SDT between 40 and 220 ppm and a sample site of 400 ppm. On the other hand, the Pb concentration range was found between 0.15 and 0.5 ppm, while As concentrations ranged between 0.01 and 0.1 ppm, depending on the study site.
