A well in Sénégal, with a woman getting water there
A well is a hole that is dug into the earth to get water (or crude oil or natural gas). Wells can be as simple as a hole that a bucket on a rope can be lowered into, or very complex with pipes and high-powered pumps to get the water out. Most cities that are not located close to fresh water lakes or rivers get their water from a well.
It is important to be careful what garbage is put into the ground near a well. If something toxic is put in the ground, it could end up in the water from the well and make people sick.
