Date of Assessment(s): January 7, 2019

Water staining from an apparent faucet leak was observed underneath the cabinet (Lab Station 9).

The leak was repaired by Building Services (Plumbing) under Work Order # 145079.

Elevated moisture was detected in the bottom portion of the cabinet and the wood facing located on the backside of the cabinet. 

Mold growth was observed on the laminated portion of the cabinet (back wall). Mold growth was also observed on the backside of the laminate and on the front of the plywood the laminate was adhered too. 

The visible mold growth was cleaned/disinfected upon discovery. Additional mold growth remains on the underside of the laminate.

Corrective Actions
January 7th, 2020

The mold impacted portions of the cabinet were removed on January 9. The water stained plywood shelf within the cabinet was stripped of its mold impacted laminated outer-shell (discarded), cleaned/disinfected and then dried out using fans. A mold inhibiting encapsulate was then coated onto the existing plywood. Once dry, a new laminated outer-shell was adhered.
