Abstract We investigated the effects of urban drainage on thewater quality of springs feeding drinking waterfountains in Lugo, a city in northwest Spain. Theparameters determined were electrical conductivity,dry residue, pH, dissolved O2, NO3 -,NO2 -, NH4 +, Cl-, organicmatter, turbidity, colour, Fe, Mn, Cu and Zn. The datawere analysed with the aid of principal componentsanalysis and cluster analysis. The first two axesextracted by principal components analysis of thesamples-by-variables matrix represented (a) salinecontamination, strongly influenced by degree ofdilution, and (b) organometallic contamination,strongly influenced by redox conditions.Within-location temporal variation in water qualitywas probably largely due to seasonal variation inrainfall amounts.
