Suspect mold found by Building Maintenance while assessing a plumbing leak.
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: August 14, 2023

Mold growth was observed within the wall cavity (some drywall removed already by Building Maintenance to access plumbing components). 

Additional moisture testing revealed elevated moisture in the drywall within the female bathroom, and outside of the female bathroom (wall in between bathroom and custodial closet door).

Moisture testing also revealed wet carpet and elevated moisture within the subfloor. 

Building Maintenance reported that they have repaired the plumbing leak. 

A board approved restoration contractor constructed a containment and removed impacted drywall in the hallway and in the female bathroom. 

Concerns with the male bathroom plumbing were also raised. Elevated moisture was detected in a section of drywall directly adjoining the sink in the male bathroom (approximately two linear feet).The drywall containing elevated moisture within the male bathroom may be due to handwashing activities or custodial floor care activities. This section of drywall was removed.  Additionally, a test cut was made in the wall in the location of plumbing piping (under the sinks). No indication of leaking was identified within the wall cavity (no visible mold growth, standing water, or water staining). 

The impacted carpet and plywood underlayment were removed as they had been wet for an undetermined amount of time. 

The subfloor also contained elevated moisture but was not impacted by visible mold growth. A test cut was made through the sub-floor to determine if there was additional impact below. Corrugated metal channels were observed under the subfloor. No signs of pooling, rusting, or odors were identified below the subfloor.

Fans and dehumidifiers were left in place over the weekend (August 19-20). The subfloor was determined to be dry on August 21, 2023.
