Disinfection Byproducts and the Wrath of Unintended Consequences

In the past century, drinking water chlorination has dramatically reduced the incidence of waterborne disease wherever it has been adopted, contributing to greater life expectancy and healthier societies.  A recent article in the journal Science (The Chlorine Dilemma, January 7) takes a fresh look at water chlorination by stacking the “pros” of this technology against...

E.Coli – The Canary in Drinking Water Systems

Waterborne diseases never sleep.  They often make a tragic comeback in the event of a natural disaster, like the earthquake in Haiti.  In that case, cholera devastated the small island nation long after the tremors ceased.  But the cholera bacterium is not the only disease-causing microbe that lurks in untreated or mistreated water:  There are...

A Public Health Giant Step: Chlorination of U.S. Drinking Water

A century ago, in 1908, chlorine chemistry’s germ-defeating properties were demonstrated in drinking water in two very different settings in the United States. First, chlorination transformed animal feed water, drawn from a highly polluted stream in Chicago’s Union Stockyards, into a product that exceeded the purity of city water. Days later, in Jersey City, chlorinated... Read More »

The Precautionary Principle Under Fire

Detractors Continue to Challenge Chlorination as a Safe Water Solution for Developing Nations.
