Molecules of groundwater can stay in the ground for weeks to thousands of years, depending on factors such as the permeability of the soil or rock, the depth of the water table, and the movement of underground currents.
Groundwater can stay underground for a few days to thousands of years, depending on factors like the geology of the area, depth of the water table, and rate of extraction. In some cases, groundwater can flow rapidly through porous rock and be replenished quickly, while in others it can be stored for long periods before recharging.
