Using complete sentences, describe the chain of events that lead to pollution of aquifers.

Answer:

Responses may vary but should include some or all of the following information: Aquifers are large bodies of water flowing beneath the surface of the earth that provide a source of drinking water to many cities and towns. Chemicals that are released on the surface seep through the ground into these aquifers. The lack of oxygen in most aquifers prevents bacteria from breaking down the chemicals, making them difficult to remove. Once an aquifer is polluted, it can remain polluted for a very long time.
