Why do some wells run dry?

Video · 1:49 · Crafty Clover explains, from A Million Whys Book 24

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do some wells run dry?

The Big Idea

A well can work for years, and then suddenly stop. Where did the water go? The water table dropped!

Below the Well

Step one: Below the Well. Wells run dry when the water table drops below the bottom of the well. Then the water is out of reach.

Causes

Step two: Causes. This can happen in a drought, when little rain soaks in. It also happens when more water is pumped out than gets refilled.

Solutions

Step three: Solutions. Shallow wells go dry first. People can dig deeper wells or save water. Using less water helps underground water recover.

A Closer Look

Let's take a closer look! A drought means less rain. Overpumping takes too much. The water table falls. The well runs dry.

Quick Facts

Quick facts! Some underground water stores take hundreds or thousands of years to refill. Short showers save lots of water. Fixing leaky taps saves water. Rain refills the ground slowly.

Think Like a Scientist

Now, think like a scientist! Keep a water-use log for one day. Write down every time you use water. Find three ways to use less water at home. Share your ideas with your family. Try one idea this week.

Outro

Wells run dry when the water table drops below the bottom of the well, because of drought or pumping out more water than gets refilled. Saving water helps it recover. Science is amazing!
