What we are reading, checking and arguing about — mold science, moisture risk, and the data behind both. Where a post states a figure, it says where the figure came from.

The five-species water-damage panel is usually presented as a list of organisms that indicate a wet building. Two of the five are extreme xerophiles that grow in conditions drier than most fungi tolerate — and that is the most useful thing about the panel, not a footnote.

NOAA's billion-dollar disasters catalogue was never a mold statistic, but it was the longest consistent record of large-scale wetting events reaching American buildings. It stopped updating after 2024, and anyone citing it now is citing a closed archive.

The Environmental Relative Moldiness Index is real science, developed by EPA researchers and peer reviewed for the job it was built to do. That job was comparing populations of houses. It is now routinely sold as a verdict on one house, and EPA has said plainly that the validation does not stretch that far.
