Plain-language report terms.

Survey

An organized inspection of the areas and materials within an agreed scope. A limited survey does not automatically cover the entire building.

Scope

The work included in the assignment: areas, materials, methods, reporting, and any exclusions.

Abatement

Work to address a regulated hazard. Lead abatement is designed to permanently address lead-based paint hazards; asbestos work may involve removal or other controlled measures. The specific meaning and requirements depend on the program.

Clearance

A post-work evaluation against the criteria that apply to the project. It may include visual examination and sampling; it is different from the original material inspection.

Sample ID

A unique label that connects a collected sample to its location record and laboratory result.

Not detected

The analytical method did not detect the substance in that sample. It does not establish that untested materials or the entire property are free of it.

Chain of custody

The record used to track a sample’s identification and handling as it moves from collection to the laboratory.

Lead risk assessment

An evaluation of lead hazards involving paint, dust, and soil, with recommendations. A paint inspection identifies where lead-based paint is located.

Mold remediation

Work to address mold-affected materials and the moisture conditions associated with the problem.

Parts per billion (ppb)

A concentration unit used in lead-in-water reporting. A number only makes sense with the sample, method, and applicable comparison criteria.
