Forensic engineering occasionally requires explaining phenomena that seem to defy the laws of nature. Such was the case recently when CTL Engineering was hired to figure out how an apartment’s bathroom shower apparently turned itself on—causing considerable mold, mildew, and moisture damage.

The case involved a brand-new apartment that had never been rented or otherwise occupied. It had never even been entered in the eight months since its final construction inspection. Eventually, a maintenance worker entered the apartment on a routine inspection and noticed something unexpected: black splotches discoloring the walls and ceiling.
