Identify deficiencies that may impact IEQ and/or sources of odor concerns. Typically includes the following depending on the nature of concern, but not limited to:
- interview/questionnaire of concern individual(s)
- inspection above drop ceiling (condition of roof deck, pipe insulation, return air plenum)
- inspection of ventilation system (operation of variable air volume box and outdoor air dampers, check controls, measurements of carbon dioxide, temperature and relative humidity, sources near outdoor air intake, measure return and supply air volume, cleanliness of coils, liner and condensate pan)
- inspection of exterior
- inspection below drop ceiling (housekeeping, sink and floor drain traps, signs of past and present moisture concern via visual and/or moisture meter, mold growth, ensure connection of current and capping of abandoned sanitary vents, odorizers, excessive plants and fabric items, identify potential pathways, and measure volatile organic compounds, carbon monoxide, and lighting)
Date(s) of Assessment: January 14 and 15, 2025
A musty odor was noted in the space upon entering. Two potential sources were identifed, the laundry room and underneath the sink associated with the island/teacher sink.
A moisture meter was used to check various wood surfaces in the space. Elevated moisture was detected in the kickplate (wood) located in the center of the island (in front of the cabinet doors).
The cove base was removed so that the kickplate could be inspected for mold growth. No visible mold growth was observed, however a malodor (musty) was identified with the kickplate.
Building Maintenance (Carpentry) removed the kickplate so that the back side of it could be assessed, as well as under the cabinet shelving. No mold growth was observed on the backside of the kickplate. No visible signs of water leaks, water staining, or visible mold growth were observed under the cabinet shelving. A malodor was present. Additional wood framing (previously inaccessible) was probed with a moisture meter. Elevated moisture was detected in other wood components under the cabinet.
Building Maintenance (Plumbing) assessed the plumbing fixtures, drains, and dishwasher. No indications of leaks/moisture intrusion, etc. were identifed.
It appears wood components associated with the island had gotten wet at some point, however the cause was not identifed. It may have been due to a historic leak that has since been corrected or due to custodial cleaning activities (too much water used during floor cleaning operations).
The faint odor in the laundry room (unrelated to the above) appeared to be associated with the washing machine. There may be some residual stagnant water in the unit or the drainage trap may be dried out.
The Office of the Environment recommended staff operate the laundry machine to purge any stagnant water and re-charge the drain trap.
The Office of the Environment recommended the components with elevated moisture be removed. Due to the difficulty in accessing these materials without damaging the remainder of the unit and due to some other minor cosmetic repairs that are needed, Building Maintenance has chosen to replace the island.
