Vulnerabilidad a la contaminación de los acuíferos someros con porosidad primaria, departamento del Quindío - Colombia

Abstract

In Colombia, as in many countries of the world, there is an increase in the threat of contamination of the groundwater resource caused by the growing demand of this water source in the development of anthropic activities. In this case study, the intrinsic vulnerability of the Glacis del Quindío aquifer system and the existing tertiary geological formations. For this analysis were used the qualitative methodologies of index widely disseminated superposition in geoscientific knowledge such as GOD - GODS – DRASTIC. The information used is processed through the technique called Algebra of Maps through ArcGis software, fed with technical information compiled by the Colombian Geological Service in recent years. From the maps obtained with the spatialization of vulnerability to groundwater contamination, there are areas with greater or less sensitivity to pollution, with a low to moderate vulnerability prevailing in the study area. This information will serve as input for the taking of preventive decisions on behalve of the competent authorities in the future formulation of the Land Management Plans - POT, guaranteeing the protection of groundwater in the Quindío department. Finally, the results were validated the results obtained through a nitrate pollution analysis (N-NO3), from the high agricultural activity developed in the region, which limits the use of this resource for human consumption.
