Clark %T Biodiversity in drinking water distribution systems:a brief review %X In drinking water distribution systems, three groups of living organisms are usually found in the biofilm and circulating water: heterotrophic bacteria, free-living protozoa, and macro-invertebrates. Indirect evidence suggests that protozoa grazing in distribution systems can partially eliminate biomass production and accidental microbiological pollution. This paper examines the biodiversit in drinking water distribution systems. %N 5 %K Water supply; Biodiversity; Food chains; Bacteria; Invertebrate larvae; Escherichia coli %P 63-70 %B The microbiological quality of water %E D.W.
