Public “Potable” Drinking Water is NOT a new issue

History:

Drinking water is water that is of sufficiently high quality so that it can be consumed or utilized without risk of immediate or long term harm.

Such water is commonly called potable water.

Access to safe drinking water is indicated by the number of people using proper sanitary sources.

Indicators of Safe Drinking Water

Global Facts:

Percentage of population with access to safe drinking water

“Due to the deaths associated with e-coli outbreaks and other pathogens that have contaminated our water supplies, there has been great concern regarding cross contamination between the potable water supply and the soil, which carries animal by-products, fertilizers and other hazardous materials”

- 2003 issue of Plumbing Standards Magazine
