Date(s) of Assessment: November 23, 2020
On November 20, 2020, the restoration contractor addressing a current water release event for the Office of Environment uncovered mold growth behind bookcases removed to address impacted drywall. The mold growth was from an unknown past event. The mold growth (~ 40 square feet) was on the drywall and the backing of two bookcases.
On November 23, 2020, the Office of Environment assessed the concern with the contractor to determine a plan of action. The backing of the bookcases were cleaned/disinfected and sealed with an encapsulant paint. Impacted drywall was removed and replaced with new. The work was performed under a negative air containment.
