Problems faced presently with water:

In this section we indispensableness to look at:
o The distribution of water
o canvas pollutants and treatment methods
o Consider roles in the water problem
scientific Facts & Principles

Distribution of the Worlds Water Supply
? Water covers more than 70% of the earth
? Of that 70%, 97% is ocean water (oceans)
? The remaining 3% consists of glaciers, fresh water and atmospherical water
? Less than 1% is considered fresh water
Because: the fresh water is either similarly expensive to retrieve, too remote to reach, or too polluted to use.
? Only .003% of the Earths total water supply is available for human usage
-This comes from both surface and terms water
