An Intro to Radney Elementary School Alexander City, AL
The World’s Water Supply If all the Earth’s water fit into a one liter (1000 mL) bottle, 97% (970 mL) of the container would be saltwater. Only 10 mL (1%, the approximate volume of a perfume bottle) would be available for drinking water (groundwater and surface water). 30 mL (3%, the approximate volume of a bottle of nail polish) would be freshwater in the atmosphere, lakes, rivers, polar ice caps, and groundwater. Only 2 drops of the freshwater would be lakes and rivers.
What does that mean for us???? All life needs water to survive!!!!!!

What is polluting our water? 2 Main Types of Water Pollution: • Point Source Pollution • Pollution that may be traced to a particular point of entry, such as a discharge pipe. • Nonpoint Source Pollution • Pollution occurring mainly through suspended and dissolved substances carried by runoff.
Potential Sources of Nonpoint Source Pollution Urban runoff Agricultural runoff • Oil & grease • Pathogens • Pesticides • Herbicides • Sediment • Nutrients • Nutrients • Pesticides • Herbicides • Sediment • Pathogens Failing septic systems • Nutrients • Pathogens
