AbstractThe composition of biofilm bacterial communities and iron corrosion scales were studied in two drinking water distribution systems transporting groundwater (DWDS-GW) and surface water (DWDS-SW). Loose corrosion products were formed containing alpha-FeOOH in DWDS-GW, while dense crystallized particles were formed in DWDS-SW, including alpha-FeOOH, Fe3O4 and CaCO3. The biofilms in the two systems had the same bacterial diversity, denitrifying functional genes and 16S rRNA gene copies, but the bacterial communities were very different. It was found that nitrate-reducing bacteria in biofilms that are associated with iron cycling played a large role in the formation of Fe3O4 and corrosion layers. (C) 2014 Elsevier Ltd.
