摘要：Natural mineral water should be characterized by chemical and microbiological purity as well as constant mineral composition. Mineral water exploitation may cause changes in their chemical composition, adversely affecting their chemical properties.This article proposes a methodology for testing the variability of selected chemical parameters of mineral waters as a factor that enables managing, and consequently preventing, aquifers from deteriorating due to excessive exploitation. To control the operation of the water extraction process, the modified cumulative sum chart (CUSUM chart) was proposed. On the basis of the card, indicating the relationship between the amount of extraction and the carbon dioxide concentration in mineral waters, the relationships between these parameters were determined. These factors may allow the control of the volume of extraction to maintain an appropriate chemical composition of the exploited water. The obtained results confirm the literature mentions the unfavourable influence of excessive water exploitation on their chemical composition.
