American Medical Association says your tap water causes cancer.
 

In 1992, the American Medical Association published statistics showing nearly 28 percent of all cancers of the intestines and 18 percent of all cancers of the bladder can be traced to chlorinated water. More than a dozen subsequent studies confirm this finding. In 1998, for instance, the journal Epidemiology published a study showing that men who drink chlorinated tap water for more than 40 years face double the risk of bladder cancer compared to men who drink non-chlorinated water.

The agency has ordered cities and towns across the United States to start reducing levels of this compound in drinking water- but chlorination will continue, even though water also can be disinfected with ultraviolet light or olone without creating CBPs. Ozone is used in some European cities- Amsterdam, Paris, Berlin, Munich and others-but chlorination continues to be the norm on this continent.

UV filters work awesome in fish tanks :):)

thanks, because of you I've stopped drinking tap water and will make it a point to try my hardest to not drink juice from those companies who use flouride as a pesticide.
