We have a project and the owner wants to include testing for mold. We had flooding in a project and two AHUs now show signs of mold. The industrial hygenist is cleaning and monitoring those units. The owner wants the areas served by the AHUs tested. We are having a hard time coming up with good standards and thresholds for the RFP.

Should the testing technician be NOCA certified? What is an acceptable level of mold in the air?
