    Guía técnica para el uso de macroinvertebrados planctónicos como bioindicadores en evaluaciones de toxicidad de efluentes - Las pulgas de agua
    (Universidad Católica Boliviana San Pablo - IUC VLIRUOS - CINAES - CICEI - Viceministerio de Recursos Hídricos y Riego, dependiente del Ministerio de Medio Ambiente y Agua, 2025) Alvizuri Tintaya, Paola; d’Abzac, Paul; Matienzo Flores, Angela Cecilia
    En este marco, la presente “Guía Técnica para el Uso de macroinvertebrados planctónicos como Bioindicadores en Evaluaciones de toxicidad de efluentes - Las pulgas de agua.” ha sido diseñada como una herramienta práctica y accesible para técnicos, estudiantes e investigadores, con el fin de apoyar el monitoreo y la gestión ambiental en cuencas como la del río Katari. Se espera que sirva como instrumento de acción hacia una gestión del agua más informada y sostenible. La Unidad de Gestión de la Cuenca Katari (UGCK) reconoce en esta guía un aporte fundamental para el fortalecimiento de la gestión integral del agua en la cuenca. Su aplicación permitirá contar con herramientas técnicas basadas en evidencia científica que faciliten la identificación temprana de riesgos y el acompañamiento a las comunidades en la protección de sus recursos hídricos. De esta manera, la guía se convierte en un instrumento clave para promover decisiones más informadas, fomentar la participación social, y avanzar hacia la recuperación y sostenibilidad de la cuenca Katari.

    Mathematical and Statistical Evaluation of Reverse Osmosis in the Removal of Manganese as a Way to Achieve Sustainable Operating Parameters
    (Universidad Católica Boliviana "'San Pablo". Programa VLIR - UOS., 2023-08-10) Alvizuri-Tintaya, Paola Andrea; Villena-Martínez, Esteban Manuel; Lo-Iacono-Ferreira, Vanesa; Torregrosa-López, Juan Ignacio; Lora-García, Jaime; d’Abzac, Paul
    Manganese is the Earth’s crust’s third most abundant transition metal. Decades of increased mining activities worldwide have inevitably led to the release of large amounts of this metal into the environment, specifically in water resources. Up to a certain level, manganese acts as an essential micronutrient to maintain health and support the growth and development of microorganisms, plants, and animals, while above a specific limit, manganese can cause toxicity in aquatic and terrestrial ecosystems. There are conventional ways to remove manganese from water, such as chemical precipitation, sorption, and biological methods. However, other treatments have yet to be studied much, such as reverse osmosis (RO), which has demonstrated its effectiveness in the removal of heavy metals and could be a suitable alternative for manganese removal if its energy consumption is reduced. This research presents mathematical and statistical modeling of the behavior of a system in laboratory-scale RO. The principal finding was that it is possible to remove Mn using the RO operated with low pressures without decreasing the sustainable removal efficiency. Reducing the operating costs of RO opens the possibility of implementing RO in different contexts where there are problems with water contamination and economic limitations.

    STUDY OF FUTURE SCENARIOS IN A DRINKING WATER SOURCE, MILLUNI CASE – BOLIVIA
    (Universidad Católica Boliviana "'San Pablo". Programa VLIR - UOS., 2023-07-10) Alvizuri-Tintaya, Paola Andrea; Avendaño-Acosta, Nithya; d’Abzac, Paul; Lo-IaconoFerreira, Vanesa Gladys
    Water is a necessary resource for life on earth, therefore, water sources for consumption must be prioritized in their care and preservation. This research takes as a study area the lagoons of the upper part of the Milluni micro-watershed, which supply two important cities in Bolivia, La Paz and El Alto. Various studies have exposed the problem of heavy metal contamination in Milluni due to mining activity in the area. However, corrective actions have not yet been taken to reduce the risk to public health and ecosystems. This study aims to identify possible future temperature and precipitation scenarios for Milluni and to observe the repercussion of the impact of the change on the area's water resources. The main result of this research is to generate specific information on the study area, which facilitates decision-making to address Milluni's water problems.
