Effect of Solar Activity Cycles on the Dnipro Water Quality Parameters

Abstract

The historical development of viewpoints on the effect of solar activity on climatic phenomena is analyzed as possible mediators in the generation of water quality changes. The quality of water delivered to the water treatment facilities of the Dnipro Water Supply Station (DWSS) in Kiev after the Kyiv Reservoir is studied. It is shown that such parameters as color and oxidability are caused by organic substances, the presence of which in water correlates with solar activity in a certain way. Using cross-correlation and wavelet analyses, the existence of a moderate correlations between solar activity and turbidity, iron and manganese content, permanganate oxidability, and total organic carbon content is shown. These parameters are likely to be varied due to climatic conditions and water supply source hydrology changes, inclusively, in the balance of water inflow to the Kyiv Reservoir.
