Evaluation of the Quality of Drinking Water and Rivers in the Mantaro Valley, Central Peru

The quality of river water is essential for the survival of living beings, whether for agricultural, livestock or human consumption. This study was carried out in the province of Junín, in different districts of Huancayo, the analysis of the samples was carried out in the continental university, from which the data were obtained for comparisons. This investigation revealed that the Chanchas river water has a higher concentration of pollutants during the afternoons since the pH is 8.69 (alkaline), being within the environmental quality standards, however these waters are not recommended for irrigation because it would cause plants do not absorb nutrients properly. Likewise, it was shown that the pH values of the drinking water of the four districts are similar, being 7.36, verifying that it is within the maximum permissible limit and suitable for consumption.
