For a current higher education project, they performed the Air Testing and it shows everything in compliance except for one room showed a level out of compliance for Formaldehyde. They are not sure what the source of this would be, as no other room with casework showed an elevated level. What other items would be a source for this that you have seen in the past? What do you suggest we do?  Somehow flush out this 1 room and retest just that room? Could this one room prevent us from getting the credit? I assume so. Please advise ASAP. Thanks!
