Abstract In August 2002, flooding in the Elbe valley caused severe damage of sewage treatment plants and networks. We investigated the impact of flooding on the bacteriological water quality (colony-forming units of saprophytic bacteria, coliform bacteria and Escherichia coli) compared with levels from previous and subsequent years. The flood introduced organic matter and elevated saprophytic bacteria levels, and a general increase of coliform bacteria. Markedly high loads of coliforms and E. coli were detected in the water column in areas where damage to sewage treatment plants was rife, exceeding the European Commission's Bathing Water Directive. The rapid disappearance from the water column may partly be caused by sedimentation creating deposits on pasture, farmland and in built-up areas, which could represent a health hazard. Future flood risk reduction should therefore be focused on the protection of sewage systems and hygienic monitoring of floodwater and flood sediments.
