Prediction of the Stability of Chemical Composition of Therapeutic Groundwater

Abstract

The aim was to assess the stability of the chemical composition of the groundwater in terms of maintaining the status of therapeutic waters in accordance with the Geological and Mining Law in Poland. The basis for the analysis was the results of stationary observations for nine hydrogeological wells for the needs of the Mineral Water Bottling Plant “Piwniczanka”. The database used for the analysis covered the years 2008–2018 and concerned the content of selected ions as well as total dissolved solids and CO2 content. For each of the analyzed boreholes, the analysis of the variability of the content was performed using graphical Schoeller–Berkaloff plots and statistical investigations (GWSDAT and STATISTICA). This hydrogeochemical investigation has demonstrated that groundwater in the Piwniczna area occur as natural “carbonated waters” and “waters containing carbon dioxide”. Summing up the analysis, it can be stated that the content of basic ions of the exploited water show a small variability and does not threaten the loss of therapeutic water status for seven of the boreholes. Two of them have a little risk of loss of therapeutic water status. Variable content of sodium ions causes changes in the hydrogeochemical type of water without affecting the maintenance of the status.

“…At the same time, these natural mineral waters are characterized by their high purity at the source, respectively free of contaminants of anthropogenic origin. Scientific literature confirms the fact that, due to their varied origin, the composition of natural mineral waters is unique for each water source and gives it a characteristic taste and specific properties, beneficial for human health, which can also be exploited for therapeutic purposes [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

“…A modified Schoeller-Berkalo diagram was carried out allowing visualizing the changing trend of the chemical composition in water samples from the study area. This type of chart is often used in similar analyses [12,54].…”
