<br />WATER FACTS
<br />In 1900 Americans consumed less Ihan
<br />5 gallons per person per day. while in
<br />1967 Americans consumed an average
<br />20
<br />
<br />of 50 gallons per person per day. In
<br />1967 Americans used 370 trillion
<br />gallons per day, and it is estimated that
<br />in the year 2000 Americans are
<br />ex.pected to use 1 Quadrillion gallons per
<br />day.
<br />There are 326,07.tooo cubic miles of
<br />water in the world found in oceans. ice
<br />fields, lakes, rivers. underground, and
<br />humidity.
<br />
<br />A cubic mile contains 1.1 trillion gallons
<br />which is more water than the U.S. will
<br />need every day by the year 2000. and is
<br />three times as much as we use today. A
<br />cubic mile would drench all of Ne....
<br />England by an inch of waler and would
<br />flood Connecticut fa a depth of one foot.
<br />
<br />317 million cubic miles are in the seas, 7
<br />million cubic mires are in polar icecaps
<br />and glaciers. 1 million in ground water
<br />more than a half mile deep, 1 million in
<br />ground water less than a half mile deep,
<br />30,000 in lakes, 16.000 in surface soil,
<br />and 300 cubic mites in rivers and streams.
<br />
<br />A city d,veUer uses ,In average of 150
<br />gallons a day, but can survive on 5 to 6
<br />pints.
<br />
<br />It takes 18a,500 gallons to make a ton of
<br />paper; 770 gallons to refine one
<br />barrel of petroleum; 600,000 gallons 10
<br />make a ton of synthetic rubber; 25,000
<br />gallons to make a ton of steel; 300
<br />gallons to make one Io..1f of bread; and 4,000
<br />gallons to provide one pound of beef.

<br />There is the same amount of water on
<br />earth today as when it was crealed 3
<br />billion years ago. It is estimated that one
<br />billion tons of sediment are ,vashed into
<br />the seas each year; sufficient to bury
<br />Washington, D.C. under 10 feet
<br />Hydrological Cycle:
<br />1. \Vater on earth surface is heated and
<br />evaporates.
<br />2. Evaporated water rises, cools, (arms
<br />clouds.
<br />
<br />;~-1\:.;
<br />
<br />3. Particles in clouds grow until they fall
<br />as snow or rain.
<br />4. Some rain or snow soaks into the
<br />earth.
<br />5. Some rain and snow falls into
<br />streams, lakes, and oceans.
<br />
<br />Hydrological cycle has no beginning _
<br />no end.
<br />
<br />At any given moment 3,100 cubic miles
<br />remain floating on douds. equivalent to
<br />one inch of rain over the entire earth
<br />every two weeks.
<br />
<br />Each year 95,000 cubic miles of
<br />moisture ascends inlo the atmoshpere;
<br />71,000 of which falls back into the sea
<br />and oceans; 15,000 strikes land, and the
<br />remainder falls into lakes, rivers. ete.
<br />
<br />One acre of corn may deliver 4,000
<br />gallons per day into the atmoshpt:>re. and
<br />one cottonwood tree may deliver 1,500
<br />gallons per day.
<br />
<br />There is enough water locked up in the
<br />Antarctic Icecap 10 feed the Mississippi
<br />River for 50,000 years. The melted ice
<br />could match flow of all rivers (or about
<br />800 years.
<br />
<br />At anyone time, the rivers contain only
<br />about 1/100th of one percent of water
<br />on the globe.
<br />
<br />The amount of water underground is
<br />3,000 limes larger than all the water in
<br />all the rivers in the world, and 20 times
<br />larger than in all lakes or inland seas,
<br />
<br />Human blood is 80% 10 90% water;
<br />muscles about 75% and bones 20%.
<br />Each day man loses 8 pints of water and
<br />can suffer to lose no more than 1/10th
<br />of the water supply in the body before it
<br />becomes fatal. 2/3 of the human body
<br />consists of water. Bread contains 35%
<br />water; meats up to 70% and fruits
<br />(tomato) up to 95%.
