The Final Barrier:
Even treated water can allow unsavory elements into your home and your drinking water as recent studies report.
• Science and technology is constantly discovering more potential contaminants in the water – such as pharmaceuticals and endocrine disrupters – including, at times, in water that has been centrally treated.
• Final Barrier treatment can stop many elements that come into the home, even after water has been centrally treated.

"...The drugs originate in wastewater discharged into the Grand River watershed, according to a McGill University report published last week in the journal Environmental Toxicology and Chemistry.
Limited quantities of certain drugs also remained in Ontario’s drinking water, even after passing through a drinking water treatment plant, researchers said." Read the story here:
Chlorine was introduced to disinfect our drinking water to make it safer to drink and many of us find the chemical taste of chlorine to be an issue but there is a darker side to drinking chlorinated water. It may be a necessary evil but it doesn't mean we have to drink it!
Long-term health effects of chlorine and its disinfection by-products (DBPs) have been studied and documented. The findings indicate that it is not chlorine on its own that’s the problem; the threat occurs when the chlorine mixes with any type of organic matter in the water and creates unhealthy by-products,Trihalomethane (THMs), the most common of which is chloroform. THMs increase the production of free radicals in the body and are believed to be highly carcinogenic.
Refer here to the Guidelines for Canadian Drinking Water:
Trihalomethanes are a group of compounds that can form when the chlorine used to disinfect drinking water reacts with naturally occurring organic matter (e.g., decaying leaves and vegetation). The use of chlorine in the treatment of drinking water has virtually eliminated waterborne diseases, because chlorine can kill or inactivate most microorganisms commonly found in water. The majority of drinking water treatment plants in Canada use some form of chlorine to disinfect drinking water: to treat the water directly in the treatment plant and/or to maintain a chlorine residual in the distribution system to prevent bacterial regrowth. The health risks from disinfection by-products, including trihalomethanes, are much less than the risks from consuming water that has not been disinfected. Utilities should make every effort to maintain concentrations of all disinfection by-products as low as reasonably achievable without compromising the effectiveness of disinfection.
The trihalomethanes most commonly found in drinking water are chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM) and bromoform. Of these, chloroform has been most extensively studied, and there are some scientific data available on BDCM. However, insufficient data are available to develop a guideline for either DBCM or bromoform. Since chloroform is the trihalomethane most often found in drinking water, and generally at the highest concentrations, the trihalomethane guideline is based on health risks linked to chloroform. This guideline applies to the total concentration of chloroform, BDCM, DBCM and bromoform.
