How far must field latrines be from a water source?

The correct distance for field latrines to be located from a water source is 100 feet. This guideline is grounded in public health principles to prevent contamination of water supplies. Latrines produce waste that can contain pathogens harmful to human health; thus, maintaining an adequate distance helps mitigate the risk of these pathogens leaching into the groundwater or being carried into the water source by surface runoff.

The 100-foot separation distance strikes a balance between practical access for users of the latrine while ensuring that potential contaminants remain sufficiently far from water supplies where individuals may draw drinking water or engage in personal hygiene activities. This standard is often dictated by military regulations and public health practices to promote hygiene and environmental safety in field operations.

Options that suggest distances shorter than 100 feet may not provide sufficient buffer to protect water sources from contamination, while options suggesting greater distances may unnecessarily complicate access to sanitary facilities. In summary, 100 feet is identified as a prudent distance to safeguard water sources and promote overall health in military settings.
