    Determinación de poblaciones vulnerables en sectores críticos de la Cuenca del Río Rocha en Bolivia
    (Universidad Católica Boliviana "San Pablo"- CReA - VLIR-UOS., 2023) Avendaño-Acosta, Nithya; Alvizuri-Tintaya, Paola Andrea; Lo-Iacono-Ferreira, Vanesa Gladys
    Rivers are ecosystems that are constituted as indicators of environmental quality thanks to the different types of environmental, and socioeconomic services they offer. Due to the constant expansion of cities, the pollution of rivers is becoming increasingly critical, especially in those rivers that cross or are close to urban centers. In developing countries, such as Bolivia, rivers are an accessible and invaluable source of water for use and consumption, so preserving their quality is essential. There are numerous studies of the water quality of the Rocha River carried out by various institutions that verified the increase in contamination in the body of water. However, the vulnerability for populations and ecosystems have not yet been identified for the entire basin. This research compiled and crossed the available information on anthropogenic activities, water quality, and population distribution to expose the impact on water quality and thus identify vulnerable populations in critical sectors of the Rocha River basin. This study is the base for formulating mitigation actions in the identified areas, to reduce the risk to public health and ecosystems.

    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.
