Macroscopic corona images of droplets of different kinds of water were examined by collecting dozens of image parameters. A statistical comparison of these parameters using Data Science (machine learning) algorithms allowed us to differentiate water types with significant accuracy. The ability to differentiate water types using macroscopic corona imaging combined with machine learning algorithms presents topics for further studies.
