How Wells Access Groundwater - Simple Cross-Section Diagram #125974 (License: Personal Use)

This diagram depicts a vertical well shaft drilled through soil and sediment layers down to the saturated zone, where groundwater resides. Arrows show water flowing radially inward toward the well casing as it’s pumped, causing the local water table to dip slightly (a cone of depression). The green surface represents land, the tan layer is unsaturated soil, and the blue region is the aquifer.

Used in educational materials, environmental science websites, municipal water resource pages, and sustainability guides to explain groundwater extraction. Matches user intent for understanding basic hydrogeology or well construction principles.
