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 20, 21, 22, 23, 24, and 28, 2024

Building Maintenance (Plumbing) had addressed the clog. The restoration contracted identifed impacted carpet and drywall in numerous areas.
Several spaces were contained with plastic and several High Efficiency Particulate Air (HEPA) filtered filtration units and dehumidifiers were placed in the work areas. A larger crew was to be assembled to perform removal of impacted materials the following day.
May 21, 2024
The Office of the Environment re-assessed the areas to ensure the contractor had identified each of the areas needing remediation. A map of the additional areas identifed was provided to the contractor.
Additional containment was installed in the main hallways to further delineate the work areas. Removal operations of porous materials (drywall and carpet) occurred during off-hours.

The odorizers were removed as not to mask a potential odor of concern.
The contractor continued removal operations of carpet and drywall (after school).
May 23 and 24, 2024
The contractor continued removal operations of carpet and drywall. The contractor also cleaned/disinfected non-porous items that may have been in contact with the overflow. Additionally, the contractor was able to begin replacing materials once removal/cleaning operations were complete. Word was conducted off-hours.
May 28, 2024
The Office of the Environment confirmed impacted materials had been removed. The remaining repair operations were turned over to Building Maintenance. It was recommended the containment remain up until sanding was complete on new drywall.
Additionally, the floor was re-cleaned/disinfected by the contractor following the repair work.
