A spilled gallon of gasoline can pollute 750,000 gallons of water. A gallon of paint or a quart of motor oil can seep into the earth and pollute 250,000 gallons of drinking water. How Much Water Does it Take to Produce Your Food? Food Most lawns only need an inch of water each week. That's enough to give every person in the world a shower for four days in a row. There are about 10 million acres of lawn in the U.S., which requires 270 billion gallons of water every week. Americans use about 1/3 more water in the summer than they do the rest of the year because they're watering their lawns. A leaky toilet can waste over 22,000 gallons of water in one year enough to take three baths every day. That's 65 glasses of water every day for a year. A leak that fills up a coffee cup in 10 minutes will waste over 3,000 gallons of water in a year.

is used for cooling electric power plants and for irrigation. about three-fourths of the fresh water withdrawn each year comes from rivers, lakes and reservoirs one-fourth comes from groundwater aquifers.
Water consumption - water that has been withdrawn and is not available for reuse in the area from which it is withdrawn. Water withdrawal - taking water from groundwater or surface-water source and transporting it to a place of use. is being diverted for farm irrigation and livestock use from natural aquatic sources. Over 600 gallons per day per person in the U.S. Snow that is 4 inches (10cm) deep contains about the same amount of water as 1/3 inch (1 cm) of rain. Surface-water runoff - precipitation that does not infiltrate into the ground or return to the atmosphere: streams, rivers, lakes, wetlands, and reservoirs. Some of this water lies too far under the earth's surface to be extracted at an affordable cost. It fills pores and fractures in layers of underground rock called aquifers. Groundwater - water which infiltrates into the ground through porous materials deeper into the earth. 
*Some of this lies too far under the earth's surface to be extracted at an affordable cost If 5 Gallons Represents all the Water on Earth (in tablespoons): Oceans Slightly more than one drop of water would fill all the rivers and lakes.Only 0.03% of one cup is in rivers and fresh water lakes.All of the water on the planet would fill less than one cup.If the Earth Were a Globe 28 Inches in Diameter:
Where Water is Found and the Percentage Oceans
This supply is continually collected, purified, and distributed in the natural hydrologic (water) cycle. In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth. If the world's water supply were only 100 liters (26 gallons), our usable water supply of fresh water would be only about 0.003 liter (one-half teaspoon). 0.5% of the earth's water is available fresh water. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil highly polluted or lies too far under the earth's surface to be extracted at an affordable cost. 
320 million cubic miles of water in the oceans. 97% of the earth's water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling). 326 million cubic miles of water on the planet. Water covers about 71% of the earth's surface.
