<br />\VATER FACTS
<br />
<br />In 1900 Americans consumed less
<br />than 5 gallons per person per day,
<br />while in 1967 Americans consumed
<br />
<br />an average of 50 gallons per person
<br />per day. In 19&7 Americans used 370
<br />trillion gallons per day, and ;1 is
<br />estimated that in the ~ar 2000
<br />Americans are expected to use 1
<br />quadrillion gallons per day.
<br />
<br />There are 326,074,000 cubic miles of
<br />water in the world found in oceans,
<br />ice fields, lakes, ri~rs, underground,
<br />and humidity.
<br />
<br />A cubic mile contains 1.1 trillion
<br />gallons which is more water than the
<br />u.S. wiU need every day Or the 1,000,
<br />and is three times as much as we use
<br />today. A cubic mile would drench all
<br />of New England Or an inch of water
<br />and would flood Connecticut to a
<br />depth of one foot.
<br />
<br />317 million cubic miles are in the
<br />seas, 7 million cubic miles are in
<br />polar icecaps and glaciers, 1 million
<br />in ground water more than a half mile
<br />deep, 1 million in ground Woller less
<br />than a half mile deep, 30,000 in lakes,
<br />16,000 in surface soil, and 300 cubic
<br />milf"S in ri~rs and slreams.
<br />
<br />A city dweller uses an i1Wrage of 150
<br />gallons a day, but can survive on 5 to
<br />6 pints.
<br />
<br />It takes 188,500 gallons to make a ton
<br />of paper; 770 gallons to refine one
<br />barrel of petroleum; 600,000 gallons
<br />to make a ton of synthetic nJbber;
<br />25,000 gallons to make a ton of steel;
<br />300 gallons to make one loaf of
<br />bread; and 4,000 gallons to provide
<br />one pound of beef.

<br />There is the same amount of water on
<br />earth today as when it was created 3
<br />billion ~af'j ago. II is estimated Ihat
<br />one billion tons of sediment are
<br />washed into the seas each year;
<br />sufficient to bury \Vashington, D.C.
<br />under 10 feet.
<br />
<br />H'ydrological C~le;
<br />1. Water on earth surface is heated
<br />and evaporates.
<br />2. Evaporated water rises, cools,
<br />forms clouds.
<br />
<br />3. Particles in clouds grow unli!they
<br />fall 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 />H'ydrological cycle has no beginning
<br />- no end.
<br />
<br />At any given moment 3,100 cubic
<br />miles remain floaling in douds,
<br />equivalenl to one inch at rain over the
<br />entire earth every two weeks.
<br />
<br />Each ~ar 95,000 cubic miles of
<br />moislure ascends into the atmosphere;
<br />n,OOO of which falls back into Ihe
<br />sea and oceans; 15,000 slrikes land,
<br />and the remainder falls into lakes,
<br />rivers, etc.
<br />
<br />One acre of com may deliver 4,000
<br />gallons per day into the atmosphere,
<br />and one cottonwood tree may deli~r
<br />1,500 gallons per day.
<br />
<br />There is enough water locked up in
<br />Ihe Anlarctic Icecap to feed the
<br />Mississippi River for 50,000 .",.ars. The
<br />melted ice could malch flow of all
<br />rivers for about 800 ~ars.
<br />
<br />At any one time, the ri~rs contain
<br />only about 1I100th of one percent of
<br />the water on the globe.
<br />
<br />The amount of water underground is
<br />3,000 times larger Ihan all the water
<br />in all the ri~rs in the world, and 20
<br />times larger than in all lakes or
<br />inland seas.
<br />
<br />Human blood is 80'%. to 90'%. water;
<br />muscles about 75'%. and bones 20%.
<br />Each day man loses 8 pints of water
<br />and can suffer to lose no more than
<br />1/1Oth of the water supply in Ihe body
<br />before it becomes fatal. 1/3 ot the
<br />human body consists of water. 8read
<br />contains 35% water; meats up to 70%
<br />and fnJits (tomato) up to 95"10.
