What is a true statement about evaporation beds?

The correct information about evaporation beds is that they are constructed to allow one square foot per soldier per day. This means that the design is based on the expected wastewater output per person, ensuring that the beds can effectively handle the amount generated while maximizing the evaporation process. This ratio helps maintain sanitation and hygiene standards in a military field environment, where managing wastewater is crucial to preventing health issues.

While there are standards regarding dimensions and ratios related to evaporation beds, option B specifically addresses the necessary space allocated to each individual, highlighting the planning and consideration that goes into constructing such facilities. This is essential for effective sanitation management in a military setting. Other options may misinterpret the environmental conditions, sizing requirements, or versatility of the system in various soil types, which do not accurately reflect the fundamental design criteria for evaporation beds.
