Officials get aggressive about mold

By:B.J. O'Brien October 18, 2002

Town and school officials met Tuesday to discuss the recent mold problems

that have been addressed at Bethel Middle School and figure out what to do

so the situation does not come up again.

The meeting was attended by First Selectwoman Judith Novachek, Selectman

Legnard and Superintendent of Schools Chesley. Also in

attendance were Vasile, the town's health director; Germnaro,

the supervisor of facility operations for the schools; and Gil Cormier, a

certified industrial hygienist.

First Selectwoman Judith Novachek pointed out that this problem isn't unique

to Bethel.

" This is an ongoing, around-the-world problem, " she said. " It's going to

take time, and it's going to take a lot of dollars [to correct]. "

During the course of the meeting, Mr. Cormier shared a list of control

measures that could be done to eliminate the mold problem altogether. He

pointed out that these recommendations weren't final.

In the short term, school officials can be on the alert for health

complaints from students and staff, vacuum the facility more frequently and

efficiently, purchase new vacuums, prohibit any wet cleaning from taking

place in the building, control and monitor the building's humidity and

purchase a new hand-held humidity reader.

Long-term recommendations include better housekeeping of the school's

heating and air-conditioning unit, removing carpets and materials that are

porous and often wet and keeping the moisture levels in the building under

control.

The mold growths were found in the school during the summer but were

determined not to be hazardous to the health of those occupying the

building.

Consultants determined that the mold most likely came from moisture that was

caused by humidity that was brought into the system and condensation on

surfaces inside the school.

Cleaning did not eliminate the problem completely, so Dr. Chesley brought

together a group of experts to look at the school's ventilation and heating

systems that could have been contributing to the problem.

The team consists of Lois , consulting engineer to the town; Bruce

Bodell, a mechanical contractor; representatives from Siemens Corporation,

the controls engineers; Mr. Cormier, Mr. Germinaro and Mrs. Vasile.

It has been pointed out that the last roofing project at the middle school

could have had something to do with the problem.

According to an HVAC mechanic, the ventilation and heating units on the roof

had been removed during repairs and were not rewired when they were put back

on.

Mr. Cormier pointed out that fresh air has played a part in the forming of

the mold. Instead of using recycled air, most of the units were open to let

air in from the outside.

" Seven of the eight units had their fresh-air intake open 100 percent, " he

said.

Mr. Cormier pointed out that too much heat in the building contributed to

the mold.

He noted that when the chillers were running, they were bringing in cool

air, and when they were off, hot air came into the building.

Most of the mold growth in the building occurred in the band room, where the

carpet was taken up. There was also mold found on instrument cases.

" Very minimal growth was detected in areas outside of the band room, " Dr.

Chesley said in an earlier written statement.

He also pointed out that the building's existing equipment had been

recalibrated to control the humidity and air movement better.

Mr Legnard pointed out that schools that have had a similar problem for a

long time have been torn down.

Mr. Cormier didn't believe that the problem at the middle school would go

that far.

" We're at the forefront where we've kind of been able to keep things in

check, " he said.

However, he did acknowledge that it is hard to take care of a system that is

as poor as the one at the middle school.

" It's difficult to operate and maintain a system that has a bad design, " he

pointed out.

Mrs. Novachek agreed, saying, " It's a horrible design that everyone knows

shouldn't be used. "

There were also some recommendations made to improve the air quality at the

school. These include monitoring and controlling the relative humidity

inside the school and maintain levels within the American Society of

Heating, Refrigeration and Air Conditioning Engineers guidelines. It was

also noted that the town should consider developing a formal program for the

operation and maintenance of the air-handling units for the school.

This would make it easier for custodians to learn how to maintain the

system.

" That becomes part of the action plan that we're looking to present, " Mr.

Cormier said.

It was also noted that it may be difficult for custodians to properly take

care of the system due to all of the other things that they have to tend to.

" We have to look at what's reasonable for people and hold people to that, "

Mrs. Vasile said.

Although the middle school is deemed safe and the mold will be eliminated

before it becomes a major health concern, Mr. Cormier noted that a lot of

exposure to mold has been known to cause health problems in the long run.

" We've seen cases of asthma increase as people spend more and more time

inside, " he said.

The purchase of cooling coils for the air-handling units was also discussed.

Mr. Cormier pointed out that the ones that are in the school are dirty.
