In the basement of the APSU library, certain shelves are taped off with blue tape displaying the word mold.
Joe Weber, director of Library Services, said the mold in the library was first noticed on the last few days of June.
“Our suspicion for the cause of the mold is a combination of a number of events. The perfect storm type of idea,” Weber said.
“I am actually the first person that discovered the mold; I found it on several of our books on level three of the library, and this was probably around the time that summer started,” said Megan Hunley, student worker for the library.
Weber said he believes the mold came from the unusually hot and humid summer coupled with the remodeling for compact shelving in the building. The doors were often open for the workmen to go in and out. Weber also said the boiler was off for most of the summer for maintenance.
“It’s my understanding that the way they regulate humidity in these large buildings is they actually run the heat and the air conditioning at the same time,” Weber said.
David Lemons, director of the Physical Plant said it is possible all of the above contributed to the situation. “Higher than normal temperatures and humidity, the back doors being open during the shelving project, and the lack of reheat.”
Lemons said the boilers were off last summer with no issues so they did not anticipate these sort of problems this summer.
“We replaced the ceiling tile, and cleaned the diffuser with a cleaning agent designed for removing mold. When we replaced the tile, we noticed the sprinkler fire system piping was also dirty, so that pipe was also cleaned. We believe that this was the cause of the mold, a condensating pipe line.” Lemons said.
Weber said if heat runs at the same time as the air, it keeps the humidity between 50 and 60 percent, which he said is ideal for libraries and office buildings. “Books are most comfortable at that humidity range and so are humans.”
He said when they took the boiler offline there was no heat coming into the building and just air conditioning with the humid air from outside caused the humidity to jump to 65 percent, which is the rate mold can grow.
Elaine Berg, coordinator of Access Services, said the first book found with mold was on the third floor and as they were moving their construction project they noticed the mold in the basement.
“The spots that seem to be the worst are close to the ceiling and cold air vents,” Weber said.
Lemons said when mold is reported to the Physical Plant, the protocol is to contact Terracon for an analysis of the situation. Terracon has a state contract and is the TBR Environmental Consultant statewide and because APSU is a TBR institution, the university uses Terracon.
Weber said they do not know what kind of mold is in the library yet. Terracon came in and did the inspection and analysis at the end of July and they are waiting on the results on the report. He said they will not clean the mold until they get the report back from Terracon.
“We would prefer to know just what we are dealing with,” Weber said.
“A few days ago they told the student workers that we would be the ones that were going to clean the mold off the books. The procedure that was established for that was that we would be in a room downstairs wearing gloves, masks and ponchos and wipe the mold off with Chlorox wipes,” Hunley said.
Hunley said after the library administration noticed the mold spreading they decided not to have anyone clean the books.
Weber said he requested portable dehumidifiers to get the humidity down. He knew the boilers were going to be down and without the heat he knew other means would be needed to bring down the humidity level. Weber said the humidifiers were on campus for five weeks.
“We got the humidity down to an acceptable level, so they went ahead and took those back because we were renting them. After they did we noticed the mold problem getting worse again.” Weber said they were about to start cleaning the mold when it started to grow again.
“It’s gotten to the point now where unfortunately, its almost out of hand and there are probably almost 3,000 books affected right now.” Weber said.
S through Z in the serial collection were just moved a week and a half ago and mold has already spread to those books, he said.
The moldy books were initially put into freezer bags and put them in the freezer at Austin’s Diner, Weber said.
“One of the ways you can get rid of the mold is to kill it by putting it in bags and suffocate it and freezing it makes the process go quicker.”
Weber said once the initial load of 700 books was done they realized there were another 2,000 or more books with mold and limited freezer space and cost issues with buying freezer bags.
“Yesterday, I told our student who was shelving that in order to reshelf the periodicals or anything with mold to wear a mask and gloves,” Berg said.
Weber said it is possible they could lose some of the books affected by the mold but after consulting with the Tennessee State Library and Archives they have methods on how to clean the books.
Weber said the library has many renovations in the future such as putting study rooms into the second floor, a seminar room, a space to host a writing center, new computer desks and furniture and the possibility for a coffee shop in the library.
“We want this to be a wonderful, pleasant place even though it’s an old building and getting rid of the mold is conducive to that and good for everyone in general,” Berg said. TAS
