A water well is an excavation or structure created in the ground by digging, driving, boring or drilling to access groundwater in underground aquifers. The well water is drawn by a pump, or using containers, such as buckets, that are raised mechanically or by hand.
Wells can vary greatly in depth, water volume and water quality. Well water typically contains more minerals in solution than surface water and may require treatment to soften the water by removing minerals such as arsenic, iron and manganese.

Famous quotes containing the word water:
“What a dissimilarity we see in walking, swimming, and flying. And yet it is one and the same motion: it is just that the load- bearing capacity of the earth differs from that of the water, and that that of the water differs from that of the air! Thus we should also learn to fly as thinkers—and not imagine that we are thereby becoming idle dreamers!”
—Friedrich Nietzsche (1844–1900)
