Final answer:
A perched water table is False. It is not a desirable or reliable source of groundwater because it is limited in extent and can quickly become depleted.
Step-by-step explanation:
A perched water table is False. The term 'perched water table' refers to a localized region above the main water table where water is trapped in an impermeable layer such as clay or rock. It is not a desirable or reliable source of groundwater because it is limited in extent and can quickly become depleted.
A reliable source of groundwater is typically found in deep, confined aquifers which are considered safer with respect to pathogens.
