THE APPLICATION OF THE STATISTICAL METHODS TO GROUNDWATER CHEMISTRY BASED ON EXAMPLE THE MAŁOPOLSKA VOIVODESHIP AREA

The aplication of selected methods of the hydrogeochemical statistical analysis is presented in the paper. Statistical methods were applied to initially identify of the formation processes of water chemical composition of groundwater within the Lesser Poland Voivodeship area. As results of the cluster analysis three clusters' set of forming the chemical composition of groundwater's was distinguished (fig. 2). A set of three factors forming the chemical composition of groundwaters was distinguished as a result of the factor analysis (fig. 3, tab. 1). All statistical methods used were found out to be susceptible upon hydrogeochemical anomaly. Taking into account the observed susceptible of cluster analysis its application makes it impossible to describe enough correctly the formation of the chemical composition of groundwaters within the study area. Using the factor analysis attained the best results but this method is also susceptible upon anomaly cases. The statistical methods used were found out as helpful. However, the interpretation of research results without the additionally factors is intractable, especially for the case of hydrogeochemical anomaly. ...
