| Popis: | Arsenic contamination in groundwater has been detected in several studies in the region of Zimapan, Mexico. Arsenic contamination sources have been reported as natural and anthropogenic. In this study, the variation in concentrations of pollutants in mineralized zones, sedimentary rocks and anthropogenic activities was determined. Arsenic and lead concentrations of 5.0–248.0 and 0.10–132.0 μg L−1 were observed in groundwater, respectively. Water mineralization was medium to medium high. Conductivity values between 198.0 and 970.0 μS cm−1 were determined. Some contaminated wells showed conductivity values as much as 1,700 μS cm−1. Open wells near mining waste showed conductivity values up to 1,485.0 μS cm−1. Groundwater showed neutral pH and alkalinity tendency. Arsenic concentrations were low in the volcanic aquifer, and high in the aquifer with carbonate rocks. The average total arsenic concentration was 47.8 μg L−1. Arsenic concentrations of 20–100 μg L−1 were observed in 93% of the sampled poin... |
