School Building Air Quality is Fast Becoming a Top Education Issue (page 3)
The crisis began in February 1999 when an ailing student in the Saugus Union School District in Santa Clarita, Calif., visited a local doctor. The doctor said blood tests revealed exposure to arsenic, formaldehyde, phenol and mold toxins that could have originated in a portable classroom. As parents panicked, the doctor quickly concluded that several hundred children had been exposed to dangerous chemicals.
A principal enlisted Neale, then a 2nd-grade teacher, to throw together an indoor air quality program. The school quickly began environmental testing and enlisted help from the U.S. Environmental Protection Agency and the state health department. But community hysteria outpaced school action. Many parents accused the school of poisoning their children and covering up a horrible secret. They organized a class-action lawsuit against the northern Los Angeles County district and the portable building manufacturer.
The mass outcry continued unabated for more than a year. But by May 2000, the state health department had confirmed the school’s findings that no serious health threats existed and had criticized the doctor’s methodologies as erroneous and invalid. The lawsuit against the school district unraveled, and the district appeased some of the most irate parents by inviting them to join its new indoor air quality oversight committee. The committee initiated policies that eliminated all pets, plants and strong perfumes and required air filter changes five times a year.
“If we had had the program in place when all this started, I can almost guarantee that this never would have happened,” says Neale, now the district’s indoor air quality coordinator and a 5th-grade teacher. “It would never have gotten to the crisis point that it had. We would never have had to spend $600,000 to crawl out from this cloud that was following us. This totally took over the district office operations because everyone was fielding air quality calls. The media was there all the time; they were calling us all the time.”
While the Saugus school crisis may be extreme, efforts to confront school environmental issues are becoming more commonplace. Eager to improve student health and performance and leery of potential litigation, administrators at school systems across the nation increasingly are tackling potential indoor air quality problems ranging from inadequate ventilation to mold and pests.
A 1995 study by the U.S. General Accounting Office showed that half the nation’s schools have at least one environmental problem. While research on the relationship between school environment and student health is still in its infancy, scientists have established that some environmental conditions, such as secondhand smoke and dust mites, can trigger asthma episodes and allergic reactions. Many school officials, fearful that unseen allergens and irritants may be hampering learning, are heeding federal government recommendations to clean up their schools.
“Definitely we’re seeing more schools taking an initiative on this,” says Elissa Feldman, associate director for the EPA’s indoor environments division. “A number of factors have combined to make the latter half of the 20th century probably worse in indoor environmental problems than the first half of the 20th century.”

The flurry of school activity can be traced back to several factors. The average public school in the United States is 42 years old. Most were built as cheaply as possible and gradually were starved for maintenance money. Cash-strapped district officials tended to cut upkeep dollars in order to save money for teachers and classroom instruction. But inattention to maintenance over several decades exacerbated problems with leaky roofs, dirty carpets and malfunctioning ventilation systems.
Meanwhile, school officials have witnessed a rise in children’s health problems, particularly asthma. Asthma is now the most common chronic childhood illness, accounting for more than 14 million missed school days each year, according to the Centers for Disease Control and Prevention.
In the mid-1990s, as staff and parents lodged more complaints about the air quality in school buildings, the EPA launched its Tools for Schools program. EPA provides schools with a free tool kit that can help eliminate five common indoor asthma triggers: secondhand smoke, dust mites, pet dander, mold and pets.
EPA’s kit provides a detailed checklist so that school administrators, teachers and maintenance staff can identify problems systematically and address them. Some indoor air quality problems can be fixed for little or no cost, including making sure that air vents are not blocked, sealing food and water to discourage cockroaches, prohibiting pets in classrooms and cleaning regularly. Other fixes may require a more costly overhaul, such as cleaning or replacing an ailing heating and ventilation system or removing old carpets that often provide a haven for dust mites.
“We’ve got about 10,000 schools implementing the kit, and many, many more are very interested,” Feldman says. “We’re now looking at getting whole school districts to adopt the kit, and it seems to be a strategy that has increasing promise.”
The New York City Public Schools have agreed to implement the tool kit in all schools, serving more than 1 million children, by school year 2005-2006. Cleveland, Ohio, Jefferson County, Ky., and schools in West Virginia are among those committed to use the tool kit, EPA officials said.
AASA and other educational organizations have held conferences and training sessions to educate superintendents about indoor air quality and Tools for Schools. The association also provides information and resources, pays travel costs for school officials to attend EPA’s annual indoor air quality conference and provides a network for urban superintendents to talk to one another about additional challenges they might confront with low-income students.
Feldman would not estimate the costs associated with Tools for Schools because schools’ indoor air quality problems vary widely. But she says attention to potential air quality problems generally saves schools money over the long term. One District of Columbia school spent $1.6 million on indoor air quality repairs, including an overhaul of the heating and ventilation system. A comprehensive indoor air quality program probably would have cost the school only about $365 annually for regular maintenance, Feldman figures.
Michael Forer, environmental health safety supervisor for the St. Cloud, Minn., Area School District 742, believes schools that ignore potential indoor air quality problems are being “penny-wise and pound-foolish.”
Forer started an indoor air quality program at his district in 1995 after watching an Oprah Winfrey show that featured EPA’s Tools for Schools. After he ordered the kit, he learned that the nurse coordinator had noticed an increase in student absenteeism as well as diagnoses of asthma and allergies. Teachers had complained about stuffy classrooms and discomfort during the school day.
He used the Tools for Schools kit to analyze building problems and formed a committee consisting of himself, the school nurse coordinator, the business manager, several principals and a school board member. He also hired a consulting firm to train district engineers.
The engineers tested carbon dioxide and humidity levels in all classrooms. They cleaned and upgraded ailing heating, ventilation and air conditioning systems. After discovering mold in carpets, Forer began a gradual carpet removal program. Animals in classrooms now are prohibited; students who bring cats, rabbits or hamsters for show-and-tell must display them in a media center or gymnasium, where custodians can immediately clean up fur or feathers.
In 2001, the EPA honored the St. Cloud district for excellence in its indoor air quality plan. Each of the district’s 19 school buildings and three administrative buildings received some work over the last seven years. Forer estimates costs have totaled between $1.5 million and $2 million, mostly for duct cleaning.
Anecdotally, school officials have noticed an apparent drop in sick days. Forer hopes to measure absenteeism and other health indicators to determine the program’s efficacy. Already, the indoor air quality program has helped change attitudes. Before the program began, administrators occasionally told frustrated teachers and staff that the problems existed only inside their heads. Now Forer encourages teachers to voice their concerns. “If they call me and say we’re having a problem, then we need to listen to that,” he says.
