The groundwater table refers to the boundary between saturated and unsaturated soil. In this context, it represents the upper level of the zone of saturation, where the soil and rock are fully saturated with water. Below this boundary, all the pores in the soil or rock are filled with water, while above it, the soil contains both air and water. Understanding this concept is crucial for pest control technicians, as many pests thrive in moist environments, often found below this saturation point. Knowledge of groundwater tables can also inform decisions about pest management strategies, especially in areas where soil moisture levels could influence pest populations.

The other choices relate to different aspects of water and soil; for instance, the level of surface water in rivers pertains specifically to above-ground water bodies, while the area where groundwater is most accessible refers to aquifer locations rather than the groundwater table itself. The layer of soil that holds moisture more generally experiences varying levels of saturation and moisture retention, but it does not specifically denote the boundary between saturated and unsaturated zones that characterizes the groundwater table.
