“Post-remediation verification (PRV) is actually a multi-step process - performed by qualified professionals - rather than just a surface or air assessment or ‘check’ at the end, and it begins in the planning stages of the remediation, is integrated with the entire process, and is ultimately a type of process or quality control embedded throughout procedures used by a professional mold remediator,” says Gordon Dean of Clean Pro Restoration, an IICRC Certified Firm. “The final step may consist of air and/or surface sampling and/or other types of testing.”

Adds Paul Tierney, Certified Mold Investigator (CMI), Environmental Scientist, and principal of Environmental Services and Consulting, LLC: “PRV involves various tools and methods, but all of these can be misleading or less than helpful if they are not used in harmony with scientific and public health principles and informed agencies such as the American Conference of Industrial Hygienists (ACGIH).”
