Robertson, 865-241-9208 As a lead agency in provid- ing support to the Depart- ment of Homeland Security, ORNL plays a critical role in water security and environ- mental management.

ORNL/ESD draws upon its long history of environ- mental management to develop new tools and technologies that address potential attacks on drink- ing water and wastewater infrastructure. Much of the work accomplished by ORNL researchers in this area over the past several years includes risk assess- ment, remedial actions, drinking water standards, wastewater treatment, and water quality monitoring.

Thus, ORNL's extensive knowledge base is being applied to water security.

The National Homeland Security Research Center oversees three major re- search areas: Water Security; Rapid Risk As- sessment; and Safe Build- ings.

The primary emphasis of Water Security is on water supply, treatment, and dis- tribution infrastructures in the United States. Key re- search areas are detection and characterization of contaminants, response and mitigation, and preven- tion and protection.

ORNL is committed to sup- porting the first area by using a systematic model and analysis of real-time data.

Today, however, U.S. citizens are increasingly aware of threats of harm to our homeland. The terrorist attacks of September 11, 2001, have taught us to anticipate that other such threats are possible.
