smaller number ofvariables, which explain main hydrogeochemical processes that control water geochemistry. Factor analysis(FA) allows discovering intercorrelations inside the data matrix and grouping of similar variables, i.e

diffusion from the marine clay, cation exchange and dissolution of carbonate and silicate minerals.Key words: factor analysis, hydrogeochemical processes, groundwater, factor loadings, Serbia.Апстракт. Мултиваријантне статистичке
