ASSESMENT OF WATER QUALITY IN SPRINGS: A CASE STUDY OF ROSTOV ON DON (RUSSIA)

Olesya Nazarenko

Abstract

Springs are one of the essential part of water suppling system in Rostov on Don. Nearly 60 springs are known to exist in the city. Rostov region is located in the arid climate zone, where there are limited natural resources of fresh groundwater. At the same time, region due to the regional hydrogeological relation is situated at the junction of four artesian basins in their regional parts focused significant resources of fresh pressure water. Springs and wells in Rostov on Don are pumped from the Azov-Kuban aquifer system. From the hydrogeological point of view, the most important is Sarmatian aquifer, which is 10 m, and in certain parts of the aquifer area even 30 m thick. Springs were sampled and analyzed for their major ion chemistry in order to assess their water quality. Groundwater has mottled mineralization and chemical composition. The chemical composition of water complex hydrocarbonate, chloride-sulfate and sulfate-chloride. Hydrogeological, environmental and landscape studies, chemical analysis of spring water for 24 components a brief field study of water, composed of the passport illustrated with photos were carried out. Mainly springs has temperature in the range of 10пїЅ - 14пїЅC. The water is generally hard. Main contamination of groundwater is connected with nutrients, especially nitrate concentrations. Groundwater generally does not fit for drinking purposes but can be used for irrigation in study area
