Global warming effects are seen around the world and
Latin American countries are not an exception, especially for
expanding drought areas. Therefore, underground water
resources use in the region is incrementing exponentially.
However, temporal and spatial underground water information
concerning availability and quality is scarce, disabling proper
decision-making. In order to close that breach, we propose and
Embedded Edge-processing IoT-based Water Quality Monitoring
system. This letter introduces the design and implementation of
this solution, specifically targeted to monitor irrigation and
drinking water extracted from water wells. The system is designed
to be deployed in central Chile, considering the topographic
conditions, which severely affect power availability and
communication resources. The captured data is stored in a data
lake, for further processing according to water quality models.
