Water quality in the ichalaya river, its relationship with the drainages of mine Matilde mine, carabuco municipality. The study of the water quality and classification of the Ichalaya River in La Paz, Bolivia, was carried out to have detailed information on the behavior of this body of water in the dry and rainy season during 2022 and 2023. Physicochemical parameters were measured in situ, and a preliminary diagnosis was made. Sampling was carried out at established points in the study area and the concentrations of anions, cations and metals were determined. From these results, the ionic balance of the water body was carried out. In conclusion, it was determined that the behavior of the body of water is of good quality until the confluence with the acidic waters of the Matilde Mine. However, along the way of the watercourse towards its mouth, the quality improves due to the contribution of tributaries, attenuating the effects of acidic waters. In this way we contribute to the management of basins for the comprehensive management of water resources, as well as the solution of environmental problems related to hydrochemistry in Bolivia.
