An odor was not detected.

The suspect mold growth was cleaned prior to the investigation.  It was reported to be on the wall in the front of the classroom. The Office of the Environment was not able to confirm the presence of mold growth.

V131 and other rooms were inspected for mold growth.  No mold growth was observed on inspected surfaces.

The drywall (exterior and interior walls) were dry as determined with the use of a moisture meter calibrated to drywall.

The rooms consist of floor tile.

The conditions above the drop ceiling were acceptable.

The tamper proof cover for the thermostat was off, but settings were acceptable parameters.

The roof top ventilation unit serving the room was in acceptable condition (cleanliness) and outdoor air damper was working.

One ceiling tile was observed to have a dry brown water stain.
