This precaution comes after routine water tests detected enterococci bacteria in the municipal water supply.
Passau’s municipal utilities responded immediately by temporarily adding chlorine to the water system. “This protective measure may cause slight changes to water taste and odor, but the chlorinated water remains safe for consumption when boiled,” explained a utility spokesperson. The boil order remains in effect pending further test results.
Concerned residents have practical questions: How long will this last? When is boiled water necessary? Officials provide clear guidance:
Must boil: Drinking, brushing teeth, food preparation
Safe as-is: Showering, laundry, toilet flushing
“We understand public concern,” said Dr. Michael Bauer, head of the health department. “While enterococci naturally occur in human and animal intestines, their presence in drinking water indicates potential contamination we must address.” Investigators are working to determine how bacteria entered the system.
This incident raises fundamental questions about water security. Though German drinking water ranks among the world’s most strictly regulated, Passau’s situation demonstrates even modern systems’ vulnerability. Experts emphasize such events remain extremely rare, with authorities’ rapid response ensuring public safety.
Daily water testing continues until the advisory lifts. The utilities promise immediate public notification when the all-clear comes. A special hotline operates for elderly and immunocompromised residents.
