Evaluación Ambiental de la calidad del agua y sedimentos del Rio Zamora de la ciudad de Loja

Abstract

Abstract: The present work focuses on the evaluation of the quality of water and sediments in the Zamora Huayco river in the city of Loja. Four samplings were carried out at ten points different during the months of April, May, July and August 2023. The results revealed a water quality index (ICA-NSF) between 60 and 81, indicating a rating between good and average. The critical parameters were fecal coliforms and BOD, influencing the decrease in ICA-NSF. It was determined that the rural stretch of the river exhibits "good quality", while the urban part presents "average quality". The Data offers a comprehensive view of water quality, identifying areas for improvement and establishing guidelines for environmental management. Determinations of sediment concentrations were made at the ten points sampling, evaluating parameters such as conductivity, pH, organic matter and heavy metals. These values ​​were compared according to Ontario regulations, the which indicates that the concentration of organic matter in the analyzed samples is below the maximum limit established for a severe impact on quality.
