Date of Assessment: September 22, 2021

A wall-mounted HVAC unit is located in the MDF Room. It was reported that the unit leaked the week of September 6th. It was also reported the unit has leaked in the past.

It was reported that Building Maintenance (HVAC) repaired the cause of the leak.

Two bookshelves (built-in) are located under the unit and were impacted by the leak. Mold growth was observed on the top-shelf of the casework and on several of the shelves beneath. Warping was also observed in several areas. 

It was reported that the books severely impacted have been disposed of. 

A hole was cut into the bookshelf to observed the back of the shelf and the wall (block) behind. No mold growth was noted behind the casework.

School staff reported that because the leak has occurred historically, they will store books in a another location. Since the shelving is no longer needed and is impacted by water damage and mold growth it will be removed.
