Homonym: well (Health)
A "well" is a structure created to access groundwater. It typically consists of a vertical shaft that reaches down to an aquifer, where water is stored underground. Wells can be dug by hand or drilled using machinery, and they are often lined with materials like concrete or metal to prevent collapse.
Water from a well is usually pumped to the surface for various uses, including drinking, irrigation, and sanitation. The quality of well water can vary, so it is important to test it regularly for contaminants. Proper maintenance ensures a reliable water supply for households and communities.
