Unexpected Places Mold and Toxins Hide — Shocking Environmental Discoveries from RTK Environmental

For more than 30 years, RTK Environmental Group has uncovered what’s really lurking in homes, schools, offices, and even cars. From mold in morgue drawers to asbestos brought home on a work shirt, RTK’s certified inspectors have seen just how far hidden hazards can reach — and how easily they can impact your health.

Here are some of the most unusual (and unforgettable) discoveries RTK has made while protecting clients from mold, asbestos, and other indoor toxins.

Mold Found Inside Morgue Drawers
Not every inspection takes place in a typical home or office. One call came from an assisted living facility asking RTK to test inside a former morgue — specifically, the drawers where bodies were stored in the 1940s. The goal was to check for hidden mold growth and ensure the space was safe for staff and residents. It’s a reminder that mold can develop anywhere moisture lingers — even in the most unexpected places.

Sick Building Syndrome: The Hidden Source of Indoor Air Problems
When employees on the third floor of a commercial building began experiencing headaches and fatigue, RTK discovered high levels of VOCs (volatile organic compounds) in the air — but no visible cause. The real culprit was a lab on the first floor with poor ventilation. Toxic fumes were traveling through the HVAC system, contaminating the upper floors. It was a textbook case of how one building’s bad air can affect everyone inside.

Mold in a Wet Bar Fridge
In one Manhattan apartment, repeated mold tests failed to clear the space, consistently identifying high levels of unusual mold spores— even though the home looked spotless. The hidden source? A wet bar’s beverage fridge. Mold had been growing behind the fan panel, releasing spores into the air every time the fridge ran. Once cleaned and repaired, air quality immediately improved. This case proves that even the smallest appliances can create big health risks.

When Mold Hides in the Kitchen
During a post-remediation inspection, multiple air tests kept failing the mold in-air sampling, showing elevated spore counts even though everything looked clean and the remediation had been correctly performed— until RTK discovered a refrigerator sealed shut during renovation. When opened, inspectors found food covered in mold, releasing spores throughout the space. The lesson? Mold isn’t always structural; sometimes it’s sitting right in your kitchen.

Mold in Cars After Flooding
After several hurricanes, RTK received calls from drivers who felt sick only when behind the wheel. Testing revealed mold growing in car ventilation systems, caused by floodwater that had soaked the vehicles before resale. Once the ducts were professionally cleaned, air quality improved and symptoms disappeared. Mold doesn’t just live in homes — it can hide anywhere air circulates.

Mold in a Mushroom Farm
One of RTK’s most unique inspections took place inside a hydroponic mushroom farm, where mold was found on a building component. The challenge was identifying which spores came from the mushrooms and which came from mold contamination. Through careful testing, RTK helped the client fix the problem without disrupting operations — and learned that even farms designed to grow fungi aren’t immune to mold problems.

The Asbestos That Came Home
In another case, a homeowner unknowingly brought asbestos dust home after helping with demolition at a relative’s house. The contamination spread through laundry, shoes, and even the family pet. It took several rounds of professional cleaning and testing before the home was safe again — a reminder that asbestos can travel easily and linger in places you’d never think to look.

What These Stories Reveal
Over the past three decades, RTK Environmental has proven that environmental hazards don’t discriminate. Whether it’s mold, asbestos, or chemical fumes, these contaminants can hide in plain sight — and their effects can be serious.
If you notice musty odors, frequent allergy symptoms, or just want peace of mind, it’s time to test.
