In this paper, the acidity and conductivity features of five kinds of water samples collected at Point Barrow, Alaska are considered. Results show that the summer precipitation is acidic, while the surface water alkaline. We also notice that the ground ice displays a weak acidic medium, which is much different from the surface water. As proved by the conductivity values, the fresh-water lake doesn’t show chemical enrichment compared to river or precipitation. Unlike other’s work at the Canadian High Arctic, positive relationship between conductivity and acidity of the precipitation samples isn’t found in our work, which means that the chemical features of the summer precipitation should be influenced by local alkiline dust to a certain extent, while the chemical features of the winter precipitation is mainly controlled by acidic sulphate particles.
