“…Previous studies have analyzed the possible water pollution in the southern portion of the aquifer; for instance: Salcedo et al [22] evaluated the pollution in a fluvial system, the implications for health, and the ecological risk in the aquatic environment (water surface, groundwater, and sediments); Flores [23] studied the hydrogeochemical processes that control the spring water quality, with emphasis on the recharge processes and water-rock interaction by using stable isotopes. On the other hand, Arroyo et al [24] assessed spring water for human consumption and analyzed the concentration of Potentially Toxic Elements (PTE) and isotopic compositions. In general, the aforementioned studies did not pay enough attention to health risk assessment, and their results show that mining waste has not influenced the geochemical composition of spring water.…”

Spring water is important for human consumption, domestic use, agricultural activities, and ecotourism in the Buenavista de Cuéllar Aquifer (ABC), southern Mexico. The objective of this research was to assess the health risk from fecal coliforms, as well as the non-carcinogenic risk to human health for different age groups, by studying the oral and dermal routes. The analysis of the cartography of high-priority springs (the result of Multicriteria Evaluation (MCE)), access routes, and knowledge of the areas with high social insecurity risk enabled the selection of 20 springs to be sampled. In situ parameters were measured, major ions, fecal coliforms, and Potentially Toxic Elements (PTE). The non-carcinogenic health risk results indicated a higher risk by the oral route in children (average Hazard index (HI) value of 0.6371) and a higher risk by the dermal route in adults (average HI value of 1.2378). The highest dermal risks are in the south-southeast of the study area. On the other hand, the assessment of health risks due to fecal coliforms resulted in a medium risk for the dry season and a high risk for the rainy season. The results of this research will serve as a key reference for the management and protection of springs in order to preserve human health.

Pb, Cd, and As concentrations were measured in blood, edible tissues, urine, feces, and hair samples from goats raised in the vicinity of the abandoned El Fraile mine tailings (Taxco de Alarcón, Mexico) to evaluate the bioaccumulation levels to Pb, Cd, and As. The goats were fed grains, grasses, and sprouts that grew on top of mine tailings and drank from the mine leachate for seven months, reproducing the natural conditions of goats raised around and on top of mine tailings. Blood showed the lowest Pb, Cd, and As concentrations, followed by edible tissues (leg muscle, brain, and lungs) whose concentrations were below Mexican permissible limits (NOM-004-ZOO-1994). However, urine showed higher concentrations of Pb and As, but feces showed even higher concentrations and hair and bezoars exhibited the highest Pb, Cd, and As values. Even though these data suggest that consuming edible tissues does not represent a risk to human health, the high Pb, Cd, and As concentrations in urine, feces, and hair suggest that goats were exposed to chronic poisoning. Additionally, isotope data indicate that Pb determined in blood, urine, and bezoars is related to the remanent mineralization present in the mine tailings, highlighting the hazard that mine tailings represent to the environment and settlers of the region.
