Groundwater is the main source of drinking water in rural areas of the Bolivian Altiplano. Recently, a widespread natural arsenic enrichment of groundwater was discovered in different areas of the Bolivian Altiplano, especially in the Poopó lake basin.
Here we present the initial results of a field campaign in which 30 drinking water wells were sam...
El agua subterránea es la principal fuente de consumo en muchos centros urbanos y áreas rurales de Bolivia, tal es el caso del Municipio de San Pedro ubicado en el departamento de Santa Cruz. El presente estudio se realizó con la Received 04 12 2021 Accepted 04 26 2020 Published 04 30 2021 Vol. 38, No.1, pp. 46-55, Ene./Abr.2021 Revista Boliviana d...
La presencia de elevadas concentraciones de arsénico encontradas en el agua de consumo de dos sitios geográficamente distantes en Bolivia, ha requerido el diseño, la construcción y la implementación de un sistema de remoción de arsénico para así obtener agua más segura para su consumo. Uno de los sitios se encuentra en una unidad educativa de la zo...
Groundwater is the main source for drinking water in rural areas in San Pedro Municipality located in the western part of department of Santa Cruz in Bolivia. This preliminary study is undertaken to determine the drinking water quality of 19 wells installed at different villages wide scattered along the municipality. Field investigations include th...
During the emergency caused by the shortage of drinking water for the city of La Paz in November 2016, the local government has used spring water to distribute drinking water to affected areas. The present study has evaluated the physicochemical and bacteriological quality of these water sources and has found that all samples of the studied springs...
Drinking water quality and the presence of natural arsenic (As) were studied in a rural, less developed area of the southern part of the Poopó lake basin in the Central Bolivian Altiplano. People in this area use untreated surface- and ground-water directly as drinking water. Water is extracted from excavated wells and from few rivers occasionally...
Dissolved arsenic (As) concentration in drinking water collected during rainy season from drilled wells in Cochabamba, Bolivia showed a range from <3.0 to 153 µg/L and averaged 30.0 µg/L, while As concentrations collected during dry season ranged from <3.0 µg/L to 581 µg/L and averaged 168.3 µg/L, showing a wide variation in the distribution betwee...
RESUMEN Se han construido y caracterizado cuatro foto-reactores tubulares de sección semi-circular, y se aplicaron al tratamiento de aguas subterráneas contaminadas con As(V), utilizando las técnica de la Remoción de Arsénico por Oxidación Solar (RAOS). Los concentradores solares fueron construidos reciclando materiales desechados: tubos de vidrio...
