2. Billions of People Lack Clean Water
2 billion people lack adequate sanitation facilities to protect them from water-borne disease
1 billion lack access to clean water altogether.

3. 95 percent of the world’s cities still dump raw sewage into their water supplies.
80 percent of all the health maladies in developing countries can be traced back to unsanitary water.

4. Contaminated Water
Over large parts of the world, humans have inadequate access to potable water (drinkable water) and use sources contaminated with disease vectors, pathogens or unacceptable levels of toxins or suspended solids.
Drinking or using such water in food preparation leads to widespread acute and chronic illnesses and is a major cause of death and misery in many countries.
Reduction of waterborne diseases is a major public health goal in developing countries.

6. Potable Water
Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm.
In most developed countries, the water supplied to households, commerce and industry meets drinking water standards, even though only a very small proportion is actually consumed or used in food preparation.

We can turn off the faucet while we brush our teeth or shave, and take shorter showers. “Doing more with less is the first and easiest step along the path toward water security.”
