Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

A lab result indicating lead-based paint in dry film is represented by which of the following?

1. 0.5% by weight

2. All layers of paint

3. 15 ppb

4. 25 ug/ft2

The correct answer is: All layers of paint

The presence of lead-based paint in dry film is accurately represented by the indication of "all layers of paint." This reflects the understanding that lead-based paint can exist in multiple layers throughout a building's paint history. Thus, when assessing a property, it is crucial to determine not just the surface layer, but also the presence of lead in any underlying layers. The other options focus on specific measures or concentrations of lead which, while important in certain contexts, do not comprehensively describe the condition of lead-based paint across all paint layers. For instance, citing percentages or micrograms per square foot denotes quantifiable concentrations or lead content in specific contexts but lacks the broader implication necessary for comprehensive risk assessment in lead-based paint evaluations.
