    Evaluación de la calidad del agua y el estado biológico de la microcuenca del Río Santa Bárbara
    (Universidad de Cuenca, 2025-02-20) Coronel Sánchez, María Karla; Poma Paredes, Stefanny Pamela; Jerves Cobo, Rubén Fernando
    The comprehensive water quality assessment and the biological status of a part of the Santa Bárbara River micro-basin identified the main factors affecting the sustainability of this water resource. Physical-chemical parameters such as dissolved oxygen, pH, temperature, nitrates, phosphates, and total dissolved solids were analyzed, along with microbiological parameters such as fecal coliforms. Biological parameters were evaluated using the Andean Biotic Index (ABI) and the Shannon-Wiener Diversity Index. The Water Quality Index (WQI-NSF) results classified water quality as ranging from "good" to "poor", while the ABI indicated a quality ranging from "moderate" to "poor" in areas with higher anthropogenic activity. The Shannon Index revealed a decline in biological diversity at heavily polluted places, confirming the loss of sensitive species in affected areas. Moreover, significant concentrations of heavy metals such as mercury and chromium were detected, exceeding the limits set by national regulations. These findings underscore the urgent requirement to implement comprehensive strategies for the monitoring and sustainable management of water resources in the region.
