Date of Report
A plumbing leak was reported to the Office of the Environment on May 19, 2019.
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(s) of Assessment: May 19, 20, 21, 22, 23, and 28, 2019

May 19, 2019 (11:45 PM)

The Office of the Environment contacted a board-approved restoration contractor to respond to the event.

The leak occurred due to a failed gasket in a custodial sink. The leak had been stopped prior to the Office of the Environment arriving onsite.

May 20, 2019 (1:00 AM)

The Office of the Environment arrived onsite to meet the restoration contractor. Both the Office of the Environment and the restoration contractor performed an assessment to delineate the area of impact

Drywall, ceiling tiles, carpet, and wood casework were primarily impacted. Water was extracted from flooring and fans and dehumidifiers were strategically placed to facilitate drying.

While removing cove base, mold growth was found behind the cove base in the administration office (hallway adjoining staff lounge). After the discovery of the mold growth, the area was contained with polyethylene sheeting and air filtration devices were placed inside the containment. Due to the limited amount identified, mold abatement activities were planned for the evening of May 20, 2019. Further assessment identified additional mold growth behind drywall and behind cabinetry within the staff lounge. Mold abatement work was rescheduled for the weekend. The area remained contained. 

The mold growth identified did not occur due to the recent plumbing leak. The mold growth identified would have been from a historical incident.

May 21 and 22, 2019

The Office of the Environment re-assed conditions. Areas were still wet and drying efforts needed to continue.

An odor was noted in the downstairs mechanical rooms. The odor seemed to be associated with areas that contained concrete walls (a mechanical room, elevator pit, and a custodial closet).

May 23, 2019

The Office of the Environment re-assessed conditions. All areas were dry with the exception of the area under containment.  Impacted portions in this area will be physically removed over the weekend.

May 24 and 25, 2019

Mold remediation activities occurred in the contained area. Impacted cove base and drywall were removed (approximately two feet beyond the area of impact). Impacted cabinetry (non-porous) was cleaned/disinfected.

The concrete block walls (downstairs) were cleaned/disinfected and then encapsulated due to the odor identified on May 22, 2019.

May 28, 2019

The Office of the Environment inspected the areas of impacted. No further action appears warranted. The response actions are intended to prevent microbiological growth.
