Findings

Date of Assessment: February 26, 2020 

A strong musty odor was detected upon entering the space. The odor seemed to be strongest in the front right corner of the classroom. 

This odor apparently had migrated to the adjoining classroom (66) over time. 

No elevated moisture was detected in or on the casework (cubbies and book-bag hangers) in the corner of the room. 

No thermal anomalies indicative of moisture intrusion were identified. 

No concerns were noted above the drop-ceiling in Room 65 or the adjoining hallways.

Several books were located on-top of the shelf in the corner of the room. One of the dividers (dividing the books) appeared to have water marks, however no other books or materials showed any indication of water staining or moisture.

One of the cubbies contained a small plastic bag. The plastic bag was opened and contained wet clothes and a strong musty odor. The bag was removed from the room by the teacher and the odor dissipated.
