System for the Acquisition and Analysis of Physico-Chemical Parameters of Surface Waters of Ferrol and A Coruña

Abstract

[Abstract] The increasing pressure of urban and industrial activities on aquatic ecosystems, plus stricter water quality standards, highlights the need for continuous monitoring. This study aims to present the planned implementation of a data acquisition framework based on the Eureka Manta+35 multiparameter probe, designed to monitor surface waters in the municipalities of Ferrol and A Coruña. Real-time measurements of pH, temperature, conductivity, turbidity, dissolved oxygen, ammonium and nitrate will be sent to the cloud via IoT. Data processing is expected to include outlier filtering, drift correction, and cross-validation with laboratory analyses. Analytical techniques such as Fourier spectral analysis, regression, and correlation will be applied to identify spatiotemporal patterns and anthropogenic impact gradients. The anticipated outcomes will enable the quantification of pollution sources, support the assessment of ecological risks, and underpin adaptive management strategies in line with European water directives.
