People are causing our water to be polluted. Businesses and cities dump chemicals and waste products into our rivers, lakes and oceans. The acid rain caused by pollution poisons water on the surface of the earth. Beneath the earth are layers of dirt and rock that act as containers for water. We call them aquifers.
Rainwater drains through the soil into the aquifers.
We call the water in the aquifer ground water. Groundwater supplies wells and springs. It is a very important source of water for all the plants and animals. Acid rain soaks into the soil. Like clean rainwater, it drains down into the aquifer.
