What is the purpose of post-remediation "clearance" testing?

Post-remediation "clearance" testing is conducted to confirm that an area has been properly remediated and is free from all contaminants, particularly microbial pathogens such as mold, bacteria, and viruses. This testing is crucial to ensuring that the remediation efforts were successful and that the environment is safe for occupants. It involves taking air and surface samples to assess the levels of contaminants and comparing them against established safety thresholds.

The goal of clearance testing is to provide assurance that the area has returned to a safe condition, which is a fundamental aspect of microbial remediation practice. It gives both remediation professionals and the occupants peace of mind that the work carried out has met industry standards for safety and cleanliness.
