They call it ''the smell'' -- a chalky, musty, damp odor at George
Wolf Elementary in Bath that seems to make some teachers and
students sick.
Despite years of air-quality tests and input from dozens of experts,
the smell's source is still a mystery to school officials.
Ripping up the school's old carpet in 2006 didn't solve the problem,
so officials have made plans to tear out old ductwork and much of
the school's air-conditioning system during a $17.19 million
renovation and expansion of the school.
But officials won't know for months whether that work will eliminate
the odor, or if the work will have been a diversion costing hundreds
of thousands of dollars.
''I guess you just hope that we're doing everything that we could
possibly do,'' Principal Michael Monaghan said, adding
that ''everyone has their opinion'' about the smell's source.
Math teacher Margaret Leibenguth said the smell forced her into an
early retirement last year.
''I was so nauseous, my eyes were burning, my throat was burning, my
ears were closing -- this was every single day,'' said Leibenguth,
whose symptoms started in 2006 after 20 years teaching at the school.
Leibenguth said her doctors diagnosed her with ''sick building
syndrome'' but never figured out exactly what caused her symptoms.
Some teachers and students reported rashes, headaches or sinus
infections, but Monaghan stressed that others have had much milder
symptoms or none at all. Student attendance rates haven't changed
noticeably from year to year, Monaghan said.
Noting that the smell seems to be worst during warm weather,
officials now say the school's air conditioning system is the most
likely culprit.
The system's ventilation ducts were built with insulation inside,
which might be starting to deteriorate. Monaghan said he spoke with
an expert at a national indoor air quality symposium in December who
agreed that replacing the ducts might help.
In addition, the Northampton Area School Board decided Monday to
replace the system's air-handling units.
All that work is now part of the school's $17.19 million renovation,
which will add 21,000 square feet of classroom space to keep up with
the school's growing student population. Engineers and district
officials agreed the best time to overhaul the air conditioning
would be while other contractors build a new gym, cafeteria and
classrooms.
More than a year before renovations began in September, other air-
quality experts suspected mold was the problem and recommended
getting rid of the building's wall-to-wall carpeting, which was
nearly worn out.
Instead, complaints about the air increased after the carpet was
pulled up. ''I can't explain that spike in the complaints,''
Monaghan said.
Because some teachers worried that concrete dust from the newly bare
floors was making the smell worse, the concrete was treated twice
with sealer, Monaghan said. Speculation about gases seeping up
through cracks in the concrete led to more tests, but they were
inconclusive.
''We've done a million things here, trying to eliminate all the
possibilities,'' said Bob Yanders, Northampton Area School
District's director of operations.
He ticked off a list of other preventive measures that haven't fixed
the problem: testing for mold and bacteria, cleaning the air-
handling units, installing air filters that use ultraviolet light to
kill germs and even testing the rocks on the roof.
As for the latest proposed solution, officials will have to wait
until construction ends next year to find out if the new air
conditioning system finally kills the smell.
''[We're] just looking forward to the renovations and construction
project to hopefully put an end to all this,'' Monaghan said.
