Water has a combination of many things in it, even when it reaches your home. According to a report sponsored by Ralph Nader, at least 2,110 different components have been found in drinking water supplies. Contaminants such as lead, asbestos, and trihalomethanes, could still be in your water supply after the water leaves the treatment plant.
