What does Box survey determine?

• A. Terrain elevation
• B. General boundaries
• C. General dimensions of contamination
• D. Marker height

Answer: (C)

Box survey focuses on estimating the size of the contaminated area. By outlining a box around the suspected zone and measuring its edges, you get a rough footprint of how far the contamination extends in different directions. This information helps establish safe perimeters and plan decontamination steps. It isn’t about terrain elevation or marker height, which involve different kinds of measurements; the box approach is specifically about the general dimensions of the contamination.
