Water-Treatment Problems

You would think that the foregoing process would be thorough enough to remove anything dangerous from the water you drink. But recent tests by the U.S. Environmental Protection Agency (EPA) indicate that small amounts of numerous chemical compounds are getting through to the faucet in some cities. A few of these compounds are known to cause cancer. The irony of this is that several are said to be compounds of the very chlorine that is added to make the waters safe!

Some doctors even present evidence that chlorine may help to trigger the cholesterol buildup in human blood vessels that is said to cause heart attacks and strokes. Joseph M. Price, M.D., asserts in his book Coronaries/Cholesterol/Chlorine that it is “one of the greatest paradoxes of recorded history” that a public health measure responsible for saving so many lives “should also unsuspectedly be responsible for many of the chronic disorders of later life.”

Though such conclusions are disputed, hundreds of cities in Europe, Russia, Canada and Japan prefer alternative methods to disinfect their water. Nice, France, for example, has used ozone instead of chlorine for over sixty years; Paris, since 1968. Ozone is an unstable form of oxygen that reacts in a chemical frenzy with water, oxidizing impurities quickly and leaving no ozone residue.

Others advocate activated carbon granules in place of, or in addition to, conventional sand in filters. Activated carbon has a unique chemical “stickiness” that “absorbs” impurities. A single pound is said to expose more than four million square feet of activated carbon surface for removing impurities. Now many U.S. environmentalists are exerting increasing pressure to force adoption of such alternatives.
