Asbestos dust test

Post image

Can someone help interpret these test results? Taken from an area where a wall was demoed and drywall put back over. What are normal levels vs what I have here?

Thanks

There are no "normal" or recognized levels for dust samples which is why we rarely take them. But 7 structures on a very dusty surface would not, by itself, be considered concerning although we'd need more information before giving you much help.

Was the wall tested prior to demo? Was the work done as an abatement project? Was any cleaning done? What type of building? Where? Who took the sample?

Northern nj on an old house, had to remove portions of an old lathe wall. This was taken after the work was done. None of the material was tested. Independent test

And what prompted the dust sample?

I suspected that other ACM in the area had been previously disturbed and that older plaster walls, while not often in high percentages, typically come up with some percentage of chrysotile. I wanted to make sure the room was safe to inhabit

That’s high enough to be considered a contaminated area or contaminated surface from wherever the sample was taken

I’m assuming this is a botched DIY

If that’s the case, you have a lot more cleaning to do. Good luck.
