The tap water is once again safe to drink for the residents of Toledo, Ohio, the state’s fourth largest city, the Associated Press reports. Toxin levels in the area’s water system caused by an algae bloom in Lake Erie were declared low enough for safe human ingestion on Monday. Whether the Eukaryotes were solely to blame for the incident is not completely clear, and investigators will be inspecting Toledo’s pipes to make certain that the aging system did not contribute to the problem.
The episode does highlight, however, the fragility of the modern city, which can be crippled not merely by hurricanes, earthquakes, tornadoes, and other natural disasters. With many people packed into a relatively small area and dependent on bureaucracies for their very survival, it’s a miracle disruption is so infrequent.
