What Are the Causes of Water Pollution?

• Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth.

Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.
