The Case of the Pink Ooze

It was the beginning of a new day. However, I received a frantic call from a facilities employee. His voice crackling with a mix of confusion and hesitation - hesitation of bringing up this subject. "There’s a pink ooze coming up from the floor," he said. I replied "Excuse me?! Pink ooze?"

In the world of Industrial Hygiene, you learn to expect the unexpected, but "ooze" usually implies a leaked drum or a long term chemical leak —not something rising from the earth like a supernatural entity. I packed some sampling jars, gloves, my camera and drove to the site.

The facilities guy wasn't exaggerating - it was pink ooze. Almost with a shade of canary yellow. The only phrase that crossed my mind was 'no shit, its ooze'. The ooze was ONLY coming from the newly renovated area of the facility. It almost looked like radioactive stalactites. I then carefully scooped the viscous substance into a jar, sealed it, and shipped it off to the analytical lab. I was totally stumped - I totally hit a dead end.

Ten days later, the results popped into email. I had to read the summary a couple times because I have never seen anything like this before. The lab report stated that it was an acidic salt— formed by chemicals used in the renovation. Two years prior, this facility had undergone a massive remodel, including brand-new flooring. Somewhere in the chemistry of the construction—the interaction between the old slab, adhesives, and the moisture trapped beneath—essentially it was a totally shitty construction job.

I had to break the news to the facilities team: the source of this "pink ooze" invasion wasn't an external leak; it was their own prized construction project. To this day, I don’t believe they’ve implemented a single corrective action. The pink ooze remains a silent, bubbling tenant of the manufacturing floor.

The Lesson Learned: Don't Cut Corners With the Construction Budget

Period. End of story.
