How Safe is our Drinking Water-both Tap and Bottled?
The World Health Organization (WHO) is an agency of the United Nations whose responsibility is “to attain by all people the highest possible standard of health” and whose mission is “to improve people’s lives, to reduce the burdens of disease and poverty, and to provide access to responsible health care for all people” (World Health Organization. Jan. 2008).
In regard to our water consumption safety, the WHO considers that “drinking-water” should be “suitable for human consumption and for all usual domestic purposes including personal hygiene” (World Health Organization. Jan. 2008). Further, the WHO goes on to submit that drinking-waters should be safe for lifetime use, taking into account of differing sensitivities that occur across life stages, including drinking water that is safe and suitable for individuals suffering from certain specific immune compromising disorders. Keep in mind, the WHO holds this accountable not just to public drinking water from the tap but also includes bottled water taken from springs and community wells.
In regard to specifics, the WHO presents first and most strongly that drinking water should be treated and that the control of fecal contamination in drinking-water systems and sources, where it occurs, is of primary importance. Fecal-specific indicator bacteria such as E. coli are the parameters of first importance in monitoring fecal pollution in both bottled and tap water. Additionally, bacteria and micro organisms that require treatment and elimination are contained in the definition and requirements of the WHO for both tap and bottled water. All of these requirements are found in the WHO’s Guidelines for Drinking Water Quality :

Guidelines for drinking-water quality, Volume 1
So how do these requirements and expectations of the WHO compare with what we are buying in bottled water and drinking from our taps? First we will look at bottled water.
The WHO’s Guidelines for Drinking Water Quality as we have already determined applies to bottle water, not just tap. Is bottle water measuring up to these guidelines and if so, is there any discrepancy within the consumer product? Research has found that bottled water, because it often sits a period of time before consuming, often times contains a specific growth situation for microbial flora; a harmful bacteria found in untreated water. Further, although bottled water is derived from “pristine” sources, they many contain or have added carbon dioxide to eliminate the bacteria’s however this often times leads to elevated temperatures while waiting to be sold and consumed. This is not good. Naturally occurring micro organisms found in all water is often times found to be higher in bottled water because of this than water that is treated and reaches us through our taps.
In regard to municipal treatment facilities (tap water), because of privacy issues, the World Health Organization cannot list what they may consider the “best” municipal treatment facilities within the United States, however, they do require each municipality to produce and distribute to the public an annual report of the water quality for human consumption. Additionally, if a facility fails to meet the Guidelines for Drinking Water standards, immediate intervention is taken.
The horizon holds many new technologies in the filtering and cleansing of the waters we ingest. Included in these new technologies are advances in: hydrological analysis, geological assessments and land use inventories to determine potential chemical and radiological contamination sites to avoid.
In conclusion, while bottled water may seem more glamorous or appear due to its marketing techniques, to be safer than tap water, the opposite may in fact be true. Consider this research when deciding on which water source you will use for yourself and your family. As always, we are here for your safety and safety education.
