Biofilm in water pipelines; a potential source for off-flavours in the drinking water.
TL;DR: Odour potent VOCs such as ectocarpene, dictyopterene A and C', geosmin, beta-ionone, 6-methyl-5-hepten-2-one, menthol and menthone were prominent compounds in biofilm in the distribution network and at raw water test sites.
