PECK PLACE FACILITIES UPDATE
INTRODUCTION
The following slides walk you through the timeline and specifics regarding the environmental issue we are currently facing at Peck with common mold.We have experienced a ‘perfect storm’ of conditions, and are in the process of two diff erent strategies:1. Professionally drying and cleaning the
Peck building.2. Developing a plan to prevent the
‘perfect storm’ from occurring again.
INTRODUCTION
The molds found through new testing at Peck are two of the 300,000 commonly-found species.
Aspergillus penicillium and Cladosporium – the types found outside and inside our homes.
They stay dormant, unless ‘excited’ by moisture, dirt, or food.
All of those conditions combined in the days following Peck’s closing.
They are non-toxic, but could affect people who have mold allergies.
Late May - Early June 2013:Extreme high temps and humidity cause
condensation to collect on the floors.
Friday, May 31st -- “Travel Agency Day.”
We called in Facility Support Services, LLC; and they tested 8 classrooms and the outside air.
No air-quality problems; no classroom safety issues.
By the following week, the classrooms were cool and dry.

Why was Peck Place safe in June?
EPA recommends -- as a ‘remediation’ tactic –that ‘dampness is mopped and/or dry-mopped within 48 hours’.
Following the heat wave, we were able to keep up with the moisture.
We ran fans.
Rooms were monitored and floors were well mopped and maintained.

Early July 2013: July 5, Principal, Eric Carbone
reported he didn’t like the way some of his classrooms looked at Peck. Classrooms were extremely hot and
humid. Chairs, which had been tipped over on
the desks, were ‘sweating’ onto the floor.
The floors and carpets had some suspicious areas he wanted checked out.

Background: “Mold contamination is present in a building when the total mold spore concentration per cubic meter is above 10,000.”
Significantly higher values of total fungi were reported in exterior (outside) areas of the school than noted for the interior classrooms and hallway.
FSS’s investigation found total spore concentrations inside Peck Place School of up to 1,860/m3, well below the 10,000/m3 level – (See chart).

NEW laboratory results indicated a significant change at Peck. This time there were higher values of total fungi inside than found outside. The same ratios apply: mold contamination is present in a building when the total mold spore concentration per cubic meter is above 10,000. FSS’s investigation found total spore concentrations inside Peck Place School of up to 24,190/m3 level (See chart).
In hot, humid weather, Peck Place is operating like a greenhouse. The ceiling tiles, which are designed to ‘breathe,’ have a layer
of insulation above them. TBD: How do we remove insulation?
The classroom uni-vents were turned off several years ago because of ‘white noise’. NOW: All are repaired and running.
Closing the windows and using commercial-grade fans only blows the same humid air around without giving it an exit point. NOW: We are running commercial grade, industrial de-humidfi ers.
We need cool, dry air circulating at Peck.
WHAT WE’VE LEARNED:
1. “Repair all leaking ceilings and pipes.” – not an issue.
2. “Check exterior drainage.” We checked the curtain drains. TBD: How, and if, to
repair curtain drains? Overgrown in some areas; covered with bark mulch in
others. We rototilled over-grown, blocked ducts out to the
parking lot. NOW: Open and flowing. Have arranged to rebuild collapsed drain and duct in
lawn (by large maple tree). SOON: Open and flowing.
EPA RECOMMENDS:
3. “Improve air-flow and increase air circulation.” OUTSIDE:
Rhododendrons and shrubbery are overgrown. Hedges block air-flow in front of windows. Cut back hedges to improve air-circulation around the
exterior of the building. Do not remove shrubbery because root systems help
with drainage. SOON: Hedges will be trimmed back from windows
EPA RECOMMENDS:
3. (cont.) “Improve air-flow and increase air circulation.”
INSIDE: Open windows, if outside air is cool and dry. NOW: Windows can now be opened 1” and still be secure. Dehumidify, if the outside air is hot and humid. Maintain interior humidity below 60%.
TBD: How? Dehumidifiers in rooms? Air-conditioning?
EPA RECOMMENDS:
4. “Maintain rooms by cleaning and dry-mopping any moisture right away (‘within 48 hours’).”
Once the building is professionally cleaned and re-inspected, we can accomplish this.
Higher level of diligence to these areas, as we had in June.
All classroom spills to be reported and cleaned immediately.
EPA RECOMMENDS:
5. “Where there is a frequent condensation, do not install carpeting.”
All area carpets have been removed from classrooms.
Children will use mats.
Carpeting in library is not an issue as the core is air-conditioned.
Teachers will keep paper and paperback books on higher shelves and plastic bins on the lower shelves.
We are professionally cleaning all wall-to-wall carpeted areas and replacing the library carpet.
EPA RECOMMENDS:
Professionally dry and clean the Peck School. J.P. Maguire has been contacted to fulfi ll this service.All areas will be cleaned.The product is ‘Benefect,’ a thymol-botanical cleaner. Investigate ‘Benefect’ HERE.Some porous materials in the classrooms will be
catalogued (for replacement) and discarded.With the experts, we will develop protocols for on-
going maintenance.
IMMEDIATE REMEDIATION: CLEANING
#1: Rebuild drain and underground duct in lawn -- in process.
#2: Trim back shrubbery to improve air-circulation around building -- next step.
#3: Repair curtain drain around building -- research.
#4: Research and Discuss:
How to remove ceiling insulation?
Possibility of air-conditioning Peck within Bond?
Possibility of stand-alone air-conditioners in these classrooms?
Dehumidifiers in these classrooms?
REMEDIATION STEPS: FACILITY
#1: Professionally clean classrooms and halls -- next step.
#3: Discard materials per professional directions -- next step.
#4: Develop protocols for on-going maintenance -- next step.
#5: Develop protocols for classroom teachers – next step.
