The Center for American Progress released Chemical Security 101, a report recommending that the U.S. Congress establish a chemical security program that requires chemical facilities - including water utilities - to assess and use "feasible alternatives that reduce the potential harm of a terrorist attack."
According to Tom Curtis, American Water Works Association (AWWA) deputy executive director, AWWA shares the Center for American Progress commitment to protect communities.
"While chemicals used in drinking water treatment keep citizens safe from waterborne disease, they must always be transported, stored and handled with great care and vigilance," Curtis said.
"Following the tragic events of 9/11, water utilities completed vulnerability assessments to help them prioritize and address security risks. Today, security remains a top priority in the design, management and operation of water facilities.
"Water providers use disinfectants to inactivate harmful microorganisms during the treatment process and to prevent contamination while the finished water is in the distribution system," Curtis said.
"While no single disinfectant is right for all systems, some form of chlorine is necessary and required by state and federal regulations for all drinking water systems using surface water, and based on new federal regulations, for some systems using groundwater."
Curtis said decisions about which disinfectant to use must ultimately be made locally. "Those decisions must take into account several factors, including source water quality, water treatment goals, regulatory requirements and storage capacity. Cost must also be examined, but it is just one of many considerations when determining the best way to assure safe water."
AWWA is currently developing a new document to help water systems evaluate disinfection methods from security, water quality, safety and other perspectives, Curtis said. The report, A Guide to Evaluating and Selecting Disinfection in a Security-Conscious Environment, will be completed the first part of next year.
Curtis said the U.S. Centers for Disease Control (CDC) regards the disinfection of drinking water as among the most significant public health advances in U.S. history. "As Congress debates new chemical security legislation, water professionals remain committed to maximizing public health protection through thorough disinfection while minimizing public safety risks," he said.
