This question tests how to keep waste separate from the water you rely on by using distance and wind direction as a buffer. The idea is to place latrines far enough from the water source so contaminants don’t reach it, and to orient them so that wind helps carry odors and vectors away from the water.

Placing latrines downwind by about 100 yards creates a safety buffer that directs any airborne contaminants, odors, and potentially flies away from the water supply. The distance reduces the chance that surface runoff, groundwater movement, or windborne particles could reach the water source, while the downwind placement helps ensure nuisance factors don’t drift toward drinking water or living areas.

Adjacency is clearly unsuitable because it would bring the latrine area in direct contact with the water source. Simply moving 100 yards without considering wind direction wouldn’t provide the same protection against windborne dispersion of odors and pests. Placing the latrine upwind could allow contaminants to drift toward the water, increasing risk.
