Water Pollution The contamination
of water by sediments, chemicals, other various substances 70% of earth ia water, and
only 3% of the 70% is
DRINKABLE!!! *Water is essential to life

*Every year twenty-five percent
of the U.S beaches are closed at least
once because of water pollution . Over two-thirds of the U.S estuaries and bays
are severely degraded because of nitrogen
and phosphorous pollution. Main contributors to Water Pollution:
