Water agencies resist push to get rid of gas chlorination
June 19, 2008

A group representing municipal water treatment plants has sent representatives to testify before Congress about legislation that would force many plants to abandon the use of chlorine gas as a disinfection tool. Chlorine gas has been used as a terrorist weapon in Iraq, and the Department of Homeland Security has made it clear that it considers the transportation and storage of chlorine gas to be a major security risk in the US. The cost to secure facilities like Omaha's Florence Water Treatment Plant against the dangers of terrorist attack could be prohibitive for many areas, which is one of the arguments the water-agency representatives are taking to the Capitol. Meanwhile, safer alternatives to gas chlorination, like solid-tablet chlorination and ultraviolet disinfection remain available to smaller facilities.
