Some students at Rolling Terrace Elementary School in Takoma Park continue to be sick and parents say persistent mold problems are to blame.
On Thursday, parents took their renewed concerns to the Montgomery County Council where Montgomery County Public Schools Facilities officials answered questions about what is happening.
They say an old HVAC system coupled with bad weather is to blame for the growth of mold in the school. Since an outbreak in September, the mold has been found again in at least 30 classrooms and other rooms.
School facilities officials say the school has been cleaned and is safe, but parents don't think so.
Bridgette Kaiser has two children at Rolling Terrace. She is also on the Parent Teacher Association. She says one of her sons has had violent bouts with asthma that flared up when school began.
"At the peak of the problem, my son was on seven different drugs for the allergies and the asthma,” she says.
School facilities officials admit the initial clean up may not have been enough.
Sean Gallagher, Assistant Director for the MCPS's Department of Facilities Management says, "The thinking is that the initial cleaning missed some spots in closets, corners and so on."
Despite the ongoing mold problem, school facilities officials say they won't begin to replace the HVAC system at the school until 2017.
In the meantime, they have hired another firm to do a widespread inspection and mold remediation. The work is expected to take about three weeks.
Bridgette Kaiser says she is not happy with the response thus far.
"It's not fair that I have to drug my kid to send him to school,” she says.
