Mold spores surge to triple historical average

Mold spore levels last week sky-rocketed to three times the historical average. (Walter Reed Army Medical Center)
Although the D.C metro region continues to dry out after the incessantly cloudy and wet September, mold spore levels remain elevated due to the lingering moisture. Today’s count of 15, 345 spores per cubic meter, while just a fraction of last week’s record high of 47,483, remains in the high range.

Susan Kosisky, microbiologist at Walter Reed’s Centralized Allergen Extract Lab reports in today to tell us last week’s levels were nearly triple the long-term average:

The daily average for the last week in September 2011 was 30,867 spores/cubic meter of air, compared to an 11 year average of 11,412 spores/cubic meter of air.
