Sistema de monitoreo en tiempo real de los niveles freático y de calidad del acuífero de la ciudad de Santa Marta: revisión del estado actual del acuífero

Resumen

This research proposes the implementation of a real-time monitoring system of the water table and quality levels of the Santa Marta aquifer, which will be integrated into the District Early Warning System. A prototype energized with a photovoltaic system and equipped with level sensors and physicochemical sensors responsible for the acquisition of data in the field will be implemented, this data will be transmitted wirelessly in real time and stored on a server with user-configurable sampling times . In the early stages of the investigation, a review of the current status of the aquifer is found based on information collected in public and private entities, the hydrological, hydrogeological, climatological and hydrochemical characteristics of the area are studied, and an inventory of deep wells is carried out. of the aquifer. From this review, a geographic information system will be created in ArcGIS to better understand the variability of the time space of the water table and water quality levels, based on Decree 1575 of 2007 on water quality for human consumption In colombia. The physicochemical parameters of water quality studied were; pH, Temperature, Dissolved Oxygen and Conductivity. These parameters were found in acceptable levels of quality, although high variability was found that could be related to the periods of drought and rainfall in the district. In addition, for the points closest to the coastline the saline intrusion can be evidenced, since these present conductivity levels more limited to the average of the aquifer. With respect to the variation of the water table, this will be strongly impacted by the increasing exploitation without ordering that the resource has had in recent years, going from 16 wells in operation for the aqueduct in 2013 to 56 wells in 2019.
