Percolation Tests questions, answered by experts

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

Often found in old insulation, tiles, and roofing materials in pre-1980s buildings.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Asbestos was commonly used in cloth wiring, but not all types of cloth wiring contain it. The age, condition, and appearance of the wiring can provide clues as to whether asbestos is present or not, but the only way to know for sure if the wiring has asbestos is to have it tested.

DIY kits are available, but professional testing ensures accurate results and compliance with regulations.
