The common method of groundwater recharge is through infiltration from precipitation or surface water sources. This process occurs when rain or melting snow permeates into the ground, passing through soil and rock layers until it reaches the groundwater table. Successful infiltration relies on various factors, including soil texture, vegetation cover, and land use. When these natural water sources fall onto permeable surfaces, such as sandy soils or rocky terrains, they can effectively replenish aquifers that supply drinking water and irrigation.

While artificial irrigation can also contribute to groundwater recharge, it is generally considered a specific man-made approach rather than a natural process like infiltration. The formation of glaciers and evaporation from lakes and rivers do not contribute directly to the recharge of groundwater. Glaciers store water in a solid form and release it slowly as they melt, while evaporation removes water from surface sources, potentially leading to decreased groundwater levels rather than recharge. Thus, infiltration stands out as the primary mechanism for replenishing groundwater supplies naturally.
