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)

Dates of Assessment:  December 27, 29, 30, 2022 and January 1 and 3, 2023

On December 24, Building Maintenance notified the Office of Environment of the incident.  A Board approved restoration contractor was utilized to dry wetted materials.

The main flooring impacted was vinyl floor tile and ceramic.  However, carpet squares at exit doorways were also impacted, thus removed, dried out, and placed back.  The small section of drywall beneath the return air grilles located in a classroom's corner wall was wetted.  The majority of building material impacted was the base of wood casework.  The base of the drywall and casework were addressed by removing vinyl cove base, drilling holes, and forcing air at the base using air movers.

The Office of Environment assessed and monitored drying with the use of moisture meters.  The Office of Environment, restoration contractor, and Building Maintenance repositioned air movers as needed during the drying process.

On December 31, the restoration contractor cleaned the floor tile since some dried grease/oils residue inherent with the sprinkler system (artifact of pipe fabrication and installation) was observed in rooms 142 and 143.

On January 1, the Office of Environment did a final assessment and all impacted materials were dry and the cleanliness of the floor tile was acceptable via comparing white glove testing pre and post cleaning.  The floor tile had what appeared to be normal blemishes following the cleaning.

On January 3, the Office of Environment received and responded to the school administration concerns about the floor tile being sticky and discolored.  No stickiness was felt.  There may have been residue noted in room 124 and outside the door of room 117.  It was decided that Facilities personnel were to determine the nature of the blemishes (present in areas not impacted by the flooding) and how the floor tile could be addressed to improve appearance (i.e. cosmetic, not an environmental concern).

The above drying activities were conducted to prevent the potential for microbial growth.
