Crews to check Kennedy Junior High for mold
By Kari Hartman Daily Herald Staff Writer
While school officials consider how to tackle elevated levels of carbon dioxide
at Kennedy Junior High, consultants also will check the Lisle school for mold
over winter break.
The probe was sparked by complaints of headaches and sinus problems from several
teachers at Kennedy. Some wonder if their health woes can be traced to the school's
Air quality officials in Naperville Unit District 203 haven't found any mold
in the school but have detected elevated levels of carbon dioxide in some areas,
said Tom Malamos, district indoor air quality manager.
The levels are not high enough to cause serious health hazards, said Les Bant,
an engineer with the DuPage County Health Department's environmental health
But officials say the carbon dioxide could create a stuffy, stale atmosphere
that contributes to headaches.
Elevated levels of carbon dioxide are not uncommon in schools or commercial
buildings, Bant said.
Health guidelines recommend carbon dioxide levels not exceed 1,000 parts per
million inside buildings, Malamos said. Some levels at Kennedy are between 1,200
and 3,000 parts per million.
The Occupational Safety & Health Administration says carbon dioxide levels
do not present a health hazard until they reach 40,000 parts per million, Bant
Some other District 203 schools also have experienced carbon dioxide levels
above 1,000 parts per million, Malamos said.
The levels vary based on several factors, Bant said. Because we exhale carbon
dioxide, levels increase with the number of people in a room. Levels also rise
if students participate in physical activities.
Kennedy Principal Don Perry said he's heard from three or four teachers complaining
of headaches or sinus congestion. They don't all work in the same area of the

teachers union President David Griffith said.
"We're interested in the health of everybody," he said. "If
people are getting sick, we have to identify that and deal with it, but they
might be getting sick for other reasons, too. Who knows?"
Kennedy will be checked room by room for mold during winter break, which runs
Dec. 23 through Jan. 3, Malamos said. School officials don't expect mold to
Administrators also are considering ways to improve ventilation at each school.
Over the past few years, the district and health department have surveyed staffs
about air quality in their buildings.
Malamos hopes to make improvements to Kennedy's ventilation system by summer.
"We want to make the best learning environment possible," Malamos
said. "This is not just unique to our district. This is seen in every school
