QUALITY CONTROL OF HYDROCHEMICAL INFORMATION IN HYDROGEOLOGICAL WORKS

In determining the spatial and temporal variability of composition groundwater, it is important to have an idea about the initial hydrochemical information and about the possibility of obtaining representative samples. Usually a partial list of solutes is determined in groundwater samples, different methods of determination can be used, having different accuracy values, there may be technical errors at all stages of receipt and storage of initial information. For the territory of Leningrad Region the reliability of hydrogeochemical data analyzed on materials of regional hydrogeological works of JSK «PCGE» and State monitoring of subsoil. The characteristic of methods validation of reliability of the samples is given according to equivalent contents of ions and the congruence between calculated and experimental dry residuum.
Keywords: groundwater quality, analysis of reliability of the hydrogeochemical data, the Leningrad Region.
