Boil water advisory in part of Amsterdam: what are gut bacteria doing in our tap water?

Water utility Waternet has issued a boil-water advisory for 130 households in Amsterdam-Zuid and Nieuw-West after E.coli and Enterococci bacteria were detected in the tap water. Residents are advised to boil water for at least three minutes to prevent potential health issues such as nausea and diarrhea, particularly for vulnerable groups like the elderly and young children. The contamination likely occurred during recent construction work, and the utility is currently flushing the pipes and testing new samples to ensure safety.
