The 1987 Schoharie Creek Bridge failure was not caused by material failure or structural overload. It resulted from foundation loss driven by hydraulic scour—a mechanism that was not fully appreciated at the time of design

The 1993 Milwaukee water contamination was not caused by a single design flaw or mechanical breakdown. It resulted from a combination of inadequate pathogen barriers, limited monitoring capability, and delayed operational response within a system that appeared compliant and functional by regulatory standards.

On April 22, 1992, a series of underground explosions ripped through the Reforma sector of Guadalajara, Mexico’s second-largest city. Over the course of roughly an hour, at least ten powerful blasts traveled along the main sewer collector, tearing open more than 8 km of streets, destroying blocks of homes and businesses, and killing over 200 people.
