“…Custodian et al (2019,2020) evaluated the presence of Cu, Pb, Fe, Zn, and As in surface waters of the aforementioned basin, using multivariate methods, revealing that "the Mantaro River continues to be a sink for discharges of mining waste and runoff of liabilities miners in the headwaters of the Mantaro basin". On the other hand, Orellana et al 10 investigated soils and pastures, indicating that although the water contains leads at high levels, this does not imply a risk for the agriculture, since the bioconcentration factors were not significant. Aylas et al 11 showed that the water of the Chanchas river (Mantaro basin) presents a higher concentration of pollutants during the afternoons, in alkaline pH conditions (8.69), being within the environmental quality standards for human consumption, but not for irrigation.…”

In the Mantaro river basin, located in Central Peru, an agricultural activity developed, even supplying the capital of Peru. An intense mining activity took place in the headwaters of this basin, and the La Oroya Metallurgical Complex was built a century ago. Mining activity has left mining environmental liabilities, which directly impact the quality of the water and the soil. In this sense, it is very important to investigate the presence of heavy metals and identify the geochemical associations present in surface waters to assess the real impact on the environment. For this purpose, 30 water samples were analyzed, collected from the Mantaro River and the channels that derive water for irrigation and animal consumption. The samples were analyzed by ICP-MS techniques, inductively coupled plasma-mass spectrometry, and ICP-AES, inductively coupled plasma-optical emission spectrometry. For the evaluation of the main physicochemical parameters, the ECA has been used, as the environmental quality standard of Peru, according to the Ministry of the Environment (2017); while for the chemical quality of surface water, the quality standards of the WHO, World Health Organization, were taken as a reference, according to the WHO guide (2017), being the elements considered: Al, As, Mn, Pb, and Zn. Investigations results show that the waters of some sectors have concentrations of As and Pb, which exceed the standards established by WHO, and there are also some specific cases (Muqui canal) in which Al and Mn exceed the WHO standard. In the case of Zn, its concentrations are much lower than the WHO standard.

The study evaluated microbial and Potentially Toxic Elements—PTEs risks in high Andean river water in Peru using Monte Carlo simulation. A total of 144 water samples were collected from four rivers and evaluated for physicochemical parameters, PTEs and bacterial pathogens. The microbial risk analysis for exposure to pathogens present in the water was based on the probability of occurrence of diseases associated with Escherichia coli, Pseudomonas aeruginosa and enterococci. PTEs risk analysis was performed using a Monte Carlo simulation approach. The results showed that the highest microbial risk due to exposure to water contaminated by E. coli, P. aeruginosa and enterococci was recorded in the Miraflores and Chia rivers. Meanwhile, the analysis of carcinogenic and non-carcinogenic risk by PTEs in adults and children revealed that the Chia river presents a high risk of contamination by PTEs, especially the carcinogenic risk for children. The Monte Carlo simulation indicated a 56.16% and 94.85% probability of exceeding the limit value of 0.0001 for carcinogenic risk in adults and children, respectively. It can be concluded that children consuming the waters of the Chia river are potentially at risk of As toxicity.
