Abstract
A strategy for representative sampling in the analysis of river water is presented. Temporal and local variations of the concentration of 11 different water components in a selected river are recorded by means of suitable samples and the multivariate-statistical methods factor analysis and multidimensional variance and discriminant analysis in an optimal manner. By means of these results and the relation of the ascertained fluctuations of concentrations to the anthropogenic pollution in the river it is possible to draw practical conclusions with regard to sampling.
