Application of chemometric techniques to the analysis of underground water from the Majorca Island

Abstract

Summary We applied three multivariate analysis techniques (principal component analysis, correspondence factor analysis and cluster analysis) to physico‐chemical data obtained by analyzing underground waters from the Majorca Island in 1987. We studied the information obtained on plotting samples and variables in the new factor space defined and found conclusions to be consistent throughout the interval studied and the occurrence of redundant information. The sample groups obtained and their relationship to the variables assayed allow hypotheses to be formulated on the geographical origin of the samples.
