Suspect mold on drywall.
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)

Date of Assessment: June 13, 2023

Mold growth was identified on the drywall. This area had previously not been visible due to a file cabinet. 

The cove base was removed in the vicinity of the mold growth on the drywall. The cove base was easily removed indicating elevated moisture was present. Moisture testing confirmed elevated moisture in the drywall. 

Mold growth was also identified behind the cove base once it was removed. 

The Office of the Environment did not observe any indication of a leak (no stained ceiling tiles, no nearby plumbing fixtures). 

The visible mold growth was cleaned/disinfected by the Office of the Environment upon discovery, however residual staining still existed.

A definitive cause was not identified; however, the leak likely occurred from an incidental spill that went unnoticed due to the file cabinets original location or too much water being used during custodial floor care activities. The file cabinets location against the wall, likely exacerbated the situation as it restricted air flow to the impacted area, hindering drying.

Corrective Actions
July 13th, 2023

The mold impacted drywall was removed and replaced (approximately six linear feet). The drywall with elevated moisture (no visible mold growth) was also replaced as it likely had been "wet" for some time.
