The Office of the Environment observed visible mold growth and staining on the vinyl gymnasium mats.
Vinyl gymnasium mats are generally nonporous; however, mold growth may result in residual staining or discoloration that can persist after cleaning and may be mistaken for active mold growth.
The Office of the Environment cleaned the gymnasium mats using a disinfectant. Following cleaning, staining and discoloration remained visible on the mats.
School administration was informed of the cleaning performed and the residual staining and discoloration. To prevent staff and students from mistaking the remaining discoloration for active mold growth, the gymnasium mats were replaced.
