Mold growth was beginning to form around the edges of student desks.

Note: The Office of the Environment has recently transitioned to a new Online IEQ platform (as of August 2018). The new platform does not allow the back-dating of IEQ concerns. This concern is inappropriately dated September 28, 2018. The concern should be dated August 8, 2018.
IEQ Investigation Process

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)

These areas were previously identified to have mold concerns in the summer, therefore the Office of the Environment was performing routine inspections as a precaution.

Additionally, the HVAC system servicing the areas was modified for the summer to assist in alleviating mold concerns.

On August 8, 2018, the start of random mold growth on edges of student desks was observed during the Office of Environment’s weekly inspection of the lower level classrooms.

The cause of the mold growth was due to extreme and continuous moist air during the summer.

Corrective Actions
August 10th, 2018

Dehumidifiers were placed in each impacted room to prevent future mold growth.

The edges of the student desks were cleaned/disinfected by custodial staff.
