La Comarca Lagunera is a region in the states of Coahuila and Durango within the Chihuahuan Desert in Mexico. It is one of the regions with the greatest industrial and economic development in the country, mainly due to agricultural activities and the mining industry. The development of La Comarca Lagunera is associated with the deterioration of natural resources, mainly due to the filtration of various pollutants in the wells where the population obtains water for drinking, in addition to the contaminants that accumulate in the soil. An evaluation and analysis of the data available in the literature, including its own results and the data from 20122022 published by CONAGUA, allowed us to determine the levels of the main pollutants in the region and their relationships with the limits recommended by Norma Oficial Mexicana NOM-127-SSA1-2021 (NOM-127), as well as the main effects on human health. The results show that the concentrations of the main water contaminants are above the values of the NOM-127, and many of the water wells with high levels of contaminants are still in use; thus, the deterioration in health has increased. On the other hand, the results of the evaluation of contaminants in the soil, mainly the compounds used as pesticides, are an important source of contamination and health problems, mainly in children. However, there is a lack of recent studies on these health problems, so collaboration between various organizations is imperative to update the data.
