Post-Remediation Verification: Why an Independent Party Should Clear the Job

Clearance is a conflict-of-interest question

When the remediation contractor also issues the clearance, the same party is grading its own homework. We perform inspection and testing only in Manhattan Beach, so a clearance result from us carries no incentive to pass or fail.

What a proper verification includes

A defensible clearance is a sequence, not a single air sample.

• Visual inspection of the containment area for remaining debris or damaged material
• Moisture readings confirming materials have dried to target levels
• Air samples inside containment plus an outdoor control
• Surface samples on cleaned materials where appropriate
• Written pass or fail with photographs and laboratory documentation

If the area fails

A failure is not a disaster. It usually means additional cleaning or continued drying is required, then a resample. Documenting a failure protects the property owner far more than a premature pass.
