Assessing freshwater pollution by CTD measurements: A holistic approach to water quality monitoring

This paper presents measurements of the MIDAS CTD instrument with Valeport profile, represented by conductivity, temperature and depth, which are fundamental in hydrographic research for any aquatic system, including freshwater lakes as Siutghiol Lake. Furthermore, these measurements provide invaluable insight into the physical and chemical properties of lake water, playing a crucial role in understanding hydrodynamics, ecology and potential environmental challenges that could be influenced by the dispersion, dilution, and transformation of pollutants. Also, due to its sensors (pH, pressure, turbidity, redox potential, florescence, dissolved oxygen, salinity, and speed of sound through water) CTD measurements provide critical data when combined with chemical and biological assessments, could give a comprehensive picture of water quality for protection and management purposes.
