Evaluación espacial de la degradación de las aguas subterráneas utilizando análisis fisicoquímicos y SIG: un estudio de caso del complejo de sótanos de Ado Ekiti, suroeste de Nigeria
Resumen
Se ha llevado a cabo una evaluación espacial de la degradación de las aguas subterráneas en Ado-Ekiti utilizando análisis fisicoquímicos y un Sistema de Información Geográfica (SIG). Se analizaron muestras de agua subterránea de 108 pozos a nivel regional. La aplicación de SIG permitió la preparación de varios mapas temáticos que se analizaron en términos de estándares de calidad del agua subterránea para consumo humano y servicios domésticos. Los mapas temáticos de pH, Dureza Total, Sólidos Disueltos Totales (TDS), Cloruros, Calcio y Nitratos producidos fueron reclasificados para su integración en un entorno GIS para producir el mapa de calidad de aguas subterráneas. Se observaron influencias antropogénicas en el estado de la calidad del agua subterránea del área de estudio, ya que el agua subterránea no potable se delineó en las áreas urbanizadas y las regiones adyacentes a los arroyos y ríos. La integración de los mapas temáticos resultó útil para la delimitación de zonas de calidad de aguas subterráneas aptas para el consumo humano y fines domésticos. El análisis espacial de la calidad de las aguas subterráneas es esencial para una adecuada comprensión de los desafíos ambientales actuales y una proyección hacia el futuro. Esto facilitará la rápida toma de decisiones para el desarrollo y manejo holístico de las aguas subterráneas.
