If dust-lead levels are equal to or greater than standards, what must be done to surfaces represented by the failing samples?

Explanation:
When dust-lead levels on a surface are at or above the allowed standard, clearance hasn’t been achieved yet. The necessary step is to re-clean the surface using the approved methods until lead dust is removed from the tested areas, and then re-test to verify that the levels now fall below the standard. The goal is to reduce contamination to acceptable levels, not to discard materials or skip cleaning. Re-testing without cleaning doesn’t address the contamination, and doing nothing is not acceptable.
