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: February 17, 2023

The sink in question is identified as "Sink 4" and is the first sink on the right, when entering the room from the main hallway. 

An active leak (slow drip) was observed underneath the sink, dripping into a container.

The countertop was delaminated in one location. This appears to be due to moisture, however no elevated moisture was detected with a moisture meter. No musty odors were detected in association with the countertop either. 

Elevated moisture was detected within the kickplate of the casework under the sink. The cove base was removed and a musty odor was detected and water staining was observed on the kickplate. The cove base was re-adhered after the assessment.

The area between the sink and the wall was assessed (required the removal of a panel). Some minor water staining was observed on the concrete (now dry). Debris such as wood and possibly drywall was observed in the cavity. 

Corrective Actions
February 17th, 2023

The Office of the Environment recommended that after the leak has been repaired to:

  • Remove the impacted kickplate and cove base due to a likely extended period of elevated moisture.
  • After the kickplate has been removed, assess any other wood components now visible since the kick plate has been removed. If feasible, remove impacted matierals. If not feasible, impacted components would need to be cleaned, dried, and then encapsulated prior reinstalling a new kick plate.
  • Re-adhere or replace the delaminated portion of the countertop to prevent water from entering. 
  • Clean/remove the debris from the cavity between the sink and the wall.
