Liquid waste disposal in field facilities relies on on-site methods that use soil to absorb and dispose of wastewater. Soakage pits, soakage trenches, and evaporation beds are all used, chosen based on soil porosity, groundwater depth, rainfall, and available space. This makes the statement true because each method serves a different way to disperse or remove water: pits provide a point for infiltration, trenches spread the wastewater over a larger area for percolation, and evaporation beds remove water through evaporation in suitable climates. The other options are not correct because they falsely limit disposal to only one method, incorrectly claim evaporation beds aren’t used in field facilities, or suggest that one method replaces another when, in practice, multiple methods may be used together depending on conditions.
