Safe Water Paradigm


-Dr Prodyot K Day

Looking at the important issues of our time, we find fresh water is most essential for the sustainment of life on this planet. It is a much agreed fact, that the pure sources of water are limited and diminishing in the face of increasing population and urbanization.

Opinion is divided about the quality of tap water, depending on whom you ask. People in charge of production and regulation of water quality of municipal water (potable water) will convince you that water is good and safe to drink. Recent publications by independent agencies like National Resources Defense Council (NRDC) and Environmental Water Group (EWG) show that water in 42 states of the USA were found to contain certain extremely toxic substances. These are contaminants recently detected, and not listed in the current list of usual contaminants as found in EPA’s Drinking Water Standard. US-EPA lists about a hundred contaminants in drinking water, including protozoan pathogens Cryptosporidium and Giardia. According to EWG report , of 141 contaminants identified, about a third (52) were linked to cancer, 41 to reproduction toxicity, 31 to development toxicity and sixteen to immune system. Not a good picture for tap water as a safe and recommended for drinking.

EPA has two levels of standards for the contaminants. National Primary Drinking Water Regulation set mandatory standard for contaminants for about a hundred compounds. National Secondary Drinking Water Regulation sets limits for an additional 15 contaminants that affect taste and aesthetics, like color and odor, but are not believed to pose any health risk. These secondary standards are nor regulated by EPA, but are stated as guidelines. Waterworks are free to comply, and record shows that half of them do not report. The conclusion is that you can not assume the water coming from your kitchen tap is safe. If you are to ensure the safety of your tap water, the final stage of purification is to be provided by yourself.

With this information it is relevant to consider how safe is the bottled waters sold in the market. Bottled water is an 11- million-dollar industry, and growing. But safety considerations are no better for bottled water. The tap water is regulated by National Safe Drinking Water Act, by state and EPA, but there is even less regulation on the bottled water industry. This leaves a grey area for the safety. Besides, the container interaction with the water is not even considered, shelf time, and non-uniform labeling leave questions unanswered and volume by volume bottled water costs 500 to 1000 times more than tap water.

The answer is to purify it at the point of use, at your kitchen tap with a Jeevan® Filter.

Jeevan® filter has adapted active carbon and redox alloy technology for a long term purification of process. There has been remarkable development in active carbon production and its' use in water purification industry. But with increasing pollution and an ever augmenting number of chemicals in water, active carbon alone cannot remove all the contaminants. A recent development in the industry is the use of metallic redox alloys that can remove a number of contaminants from water which are not removed by active carbon. A proper combination of redox alloy and granular active carbon (GAC) has provided an affordable solution in almost complete removal or reduction, to meet the maximum contaminant level (MCL) of chemicals, from tap water. Although EPA was reluctant to approve such point of use (POU) purifiers, they now believe this is the only way to purify tap water for drinking and cooking purpose. Some of these purifiers can be used for a year before changing of the filter cartridge, so that cost of water comes to less than a penny per liter of good tasting, safe and healthy water. — Dr. P. K. Day, a Houston-based toxicologist, has developed a water filter for domestic use. It is called the Jeevan® Water filter, Point of use purifier.
