What is water?Chemical substanceChemical Formula: H2O
One Oxygen, Two Hydrogen Connected with a Covalent Bond
State:Liquid in ambient conditionsAlso exists on earth in
solid state (ice) Gaseous state (water vapor / steam)

TidbitsCan also exist as liquid crystal state (near
hydrophilic surfaces)Using standard chemical compound
nomenclature it is…dihydrogen monoxide

Drinking WaterEssential to humans and other lifeformsAccess has improved but…
1-2 Billion (depending on source) lack access>2.5 Billion lack access to adequate sanitation
(see the problem?)
Clear correlation between access to safe water and GDP per capita

Predictions for …
2025: > ½ of the world population will face water-based vulnerability
2030: Some developing regions of the world, water demand will exceed supply by 50%

EconomyFunctions as a solvent for a wide variety of
chemical substances and facilitates industrial cooling and transportation.
Approximately 70% of the fresh water used by humans goes to agriculture.

Water Filters: •Remove impurities from water by using a • fine physical barrier | a chemical process | or a biological process.
•Cleanse water to various extents for :• irrigation, • drinking water, • aquariums, and• swimming pools.
