Se midieron parámetros fisicoquímicos in situ, y se realizó un diagnóstico preliminar. Se realizó la toma de muestras en puntos establecidos en el área de estudio y se determinó las concentraciones de aniones, cationes y metales. A partir de estos resultados se realizó el balance iónico del cuerpo de agua. Como conclusión se determinó que el comportamiento del cuerpo de agua es de buena calidad hasta la confluencia con las aguas acidas de la Mina Matilde. Sin embargo, en el trayecto del curso de agua hacia su desembocadura, la calidad mejora por el aporte de afluentes llegándose a atenuar los los efectos de aguas acidas. De esta forma coadyuvamos en la gestión de cuencas para el manejo integral del recurso agua, como en la solución de problemas ambientales referidos a la hidroquímica en Bolivia.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract 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.]]></p></abstract>
