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 23, 24 and 26, 2020

The impacted cabinetry had been removed by Building Services on June 22. The cabinetry was reportedly discarded due to an odor. Building Services had also placed two fans to dry the impacted areas of carpet (approximately 30 square feet).

The Office of the Environment arrived on June 23:

The leak originated from inside a block wall. The block wall is currently inaccessible.

Moisture was detected within the carpet. Further inspection revealed that moisture had gotten underneath of the carpet. The carpet was peeled back to dry the concrete slab and undersides of the carpet.

A closet adjoins the area of impact. The closet is finished with drywall. Slightly elevated moisture was detected in the drywall. A hole was cut into the drywall to observe the backside of the drywall and facilitate drying. No mold growth was observed on the backside of the drywall and a fan was repositioned to force air behind the wall cavity. No cove base was present on the drywall.

June 24, 2020:

Building Maintenance cut a hole into the block wall and reportedly repaired the cause of the leak. 

The Office of the Environment observed the cavity. No standing water, odors, or suspect mold growth was observed.

June 26, 2020:

The Office of the Environment confirmed impacted areas were dry and ready for replacement of cabinets and re-adhesion of carpet.
