Many experts now agree that if you live in an area on a municipal water system, then there is little you need to be worried about. Canada has some of the best water and testing practices in the world and the only real concern is Chlorination by products. Chlorination byproducts are chemicals that result from the reaction of chlorine with organic substances in water. In areas with high TDS events or older water delivery systems, larger amounts of chlorine are required to provide acceptable deactivation levels of pathogens in the water. This greater amount of added chlorine then reacts with the organics in the water and on the pipe walls which react to for these disinfection by-products. Trihalomethanes (THMs) refer to one class of disinfection by-products found in nearly every chlorinated public water supply to some extent. The most prevalent is chloroform (trichloromethane), a THM which is carcinogenic to rats and mice. The principle method for removal of chlorination by-products like chloroform is by activated carbon adsorption. So what is generally recommended, and what I do is run all my drinking water through an activated carbon filter (Brita, undersink, refridgerator). I drink exclusivly Calgary/Vancouver tapwater filtered through carbon and feel that it is the best for me and my family as well as the Environment.
PS Brita Filters can be recycled. Google it!
