The firefighter union president Jason J. Burns says that they hope to know the results of the air testing after the cleaning by Wednesday morning.
But he also said that the problem likely needs more than a band–aid solution because the station is almost 120 years old.
Built in 1900, Burns says the foundation of the building is porous, and the roof is leaky, which means water gets trapped inside.
"All that kind of settles down in the basement," said Burns. "It's dark, it's dingy, not a lot of air movement."
