On water chlorination

We have been arguing against the practice of water chlorination for some time. Though water disinfection is an important tool to promote public health, we do not believe that this is the proper method to do so.

Now, there is a study (“New toxic byproducts of disinfecting water“, source: ScienceDaily) that water chlorination produces toxic byproducts:

found the compounds 2-butene-1,4-dial (BDA) and chloro-2-butene-1,4-dial (or BDA with chlorine attached). BDA is a very toxic compound and a known carcinogen that, until this study, scientists had not detected in chlorinated water before…

Given that there are alternative methods of disinfecting tap water, such UV radiation, this study strengthens our believe that water companies should stop the use of chlorination.
