Impacto de Actividades Mineras en la calidad de aguas en la Cuenca hidrográfica del río Amarillo, en período Enero-Junio 2023.

Abstract

Water is essential element on the planet, more than 70% of the earth´s surface is covered by water in the ocean, seas, rivers and lakes, and 2,5% of water is freh, evidence that it is a fundamental resource for human begins, animals and agricultural development. The present work was carried out in the Yellow river basin belonging to the Portovelo canton in the province of El Oro, located at the coordinates: Latitude: 3°43′17″ S, longitude: 79°37′18″ W, at an altitude of 608 msnm. With the objective of determining the impact of mining activities in warer quality in the Yellow river basin. Twelve water samples were collected randomly at four points where the water from the metal mining benefit plants is discharged, the procedure was carried out two measurements (january and may) at the georeferenced points where mining activities are carried out in the Yellow river basin. The water samples were taken to the Nemalap laboratory, obtaining the respective results and interpretation of the water análisis for human consumption according to INEN 1 108:2006 standards, allow us to compare the results between the mining plants to determine whether or not there are significant differences between them during the development of the activity, analyzing their physical and chemical properties od the water. If there were significant statistical differences between the mining plants, the Duncan's rank and multiple comparisons test was applied. In January, water hardness in areas of where discharge from the mining plants showed the highest values in PLAMI3 (𝑋̅=609,1 mg/l), higher than LMP (300 mg/l). For carbonate in water in the months of january an may, there no statistial differences with a value of 0,0 mg/l in the mining plants.
