What Is Post-Remediation Testing?

Post-remediation testing, also known as a clearance assessment, is a final inspection and sampling process performed after a hazardous material like lead or asbestos has been professionally removed (abated). Many renovation and demolition projects legally require initial testing for these hazards. If they are found, a licensed abatement contractor must contain and remove them. However, the project isn’t finished yet.

A clearance assessment is the final, mandatory step that verifies the abatement was successful and the area is safe for re-occupancy and for your project to continue.

Testing After Lead Abatement

Passing a lead clearance assessment is a multi-stage process performed by a certified inspector to ensure your property is safe. Our process confirms that the abatement was successful by meeting stringent standards at each step.

To receive a passing report, the following steps must be completed:

  • Visual inspection: First, a meticulous visual check is conducted inside the containment area. Our lead testing inspector searches for any visible dust, debris, or paint chips. The area must be completely clean to proceed.
  • Dust wipe sampling: Once the visual inspection passes, our technician collects dust wipe samples from floors, window sills, and other surfaces.
  • Laboratory analysis: These samples are transported to our testing laboratory. Using advanced technologies like X-Ray Fluorescence (XRF) analyzers and Flame Atomic Absorption Spectrometry (FAAS), we precisely measure the lead concentration to verify it is below the safety thresholds established by the EPA.

Testing After Asbestos Remediation

Clearance testing after asbestos work is a highly regulated procedure that must be performed by an AHERA-certified professional to ensure the area is safe for re-occupancy. The process is designed to detect even microscopic, invisible fibers in the air. The asbestos clearance process strictly follows these steps:
  • Visual inspection: An AHERA-certified asbestos inspector conducts a thorough visual examination to confirm the work area is clean, dry, and free of any remaining asbestos-containing material or residue.
  • Aggressive air sampling: To simulate worst-case, active conditions, we perform “aggressive” air sampling. This involves using fans to stir the air and dislodge any microscopic fibers that may have settled onto surfaces during abatement.
  • Microscopic analysis: The air samples are analyzed in our laboratory using Phase Contrast Microscopy (PCM), a method that allows us to count the number of airborne fibers.
  • Passing criteria: An area officially passes clearance only when the analysis confirms the airborne fiber concentration is below the established safety standard of 0.01 fibers per cubic centimeter (0.01f/cc).

Do You Need a Post-Abatement Clearance Assessment?

Yes. If your property required professional lead or asbestos abatement, then a post-abatement clearance assessment is not just recommended — it is often a legal requirement. This independent, third-party verification is your official proof that the remediation was successful. Your project cannot move forward, and the area cannot be safely reoccupied, until it passes a clearance test. If the assessment fails, the abatement contractor will be required to re-clean the area, and the clearance process must be repeated until the standards are met.

The benefits of professional post-abatement clearance testing include:

  • Health and safety: Provides certified proof that the air and surfaces in your property are safe for family, tenants, or employees.
  • Regulatory compliance: Fulfills legal requirements, allowing construction and renovation projects to resume without delay.
  • Verification of work: Independently confirms that the abatement contractor’s work was successful and complete.
  • Legal documentation: Creates an official record that the property has passed safety clearance, protecting you from future liability.

Can You Get Post-Abatement Clearance Testing Performed by a Remediation Company?

No, and this rule is in place to protect you. Regulations in Oregon and Washington mandate that the company performing the abatement cannot be the same company that performs the final clearance testing. This required separation ensures there is no conflict of interest and that the results are completely unbiased.

Think of it as an independent audit; one company does the work, and a separate, expert firm like ours verifies that the work was done correctly. This system is designed to protect public health and guarantee that when your property passes clearance, it is truly safe.
