Findings

Date of Assessment: July 23, 2025

On July 23, 2025, the Office of the Environment observed visible mold growth (one to two square feet) and water staining on the lower portion of drywall within Portable 150. The area was probed with a moisture meter and no elevated moisture was detected, indicating an active moisture source was not present at the time of sampling. 

A definitive cause was not identified; however, the source was likely due to too much water being used during custodial floor care activities.
