Which value represents the EPA dust level standard for window wells/troughs?

Explanation:
Dust-lead hazard standards set permissible lead levels on different surfaces after lead-based paint work. Window wells and troughs have a higher allowed level because these areas are harder to clean and accumulate dust more readily. The value for window wells/troughs is 400 micrograms of lead per square foot (μg/ft2). So samples from window wells/troughs must be at or below 400 μg/ft2 to meet the standard. For comparison, floors are 40 μg/ft2 and window sills are 250 μg/ft2.
