I’m always impressed by the countless men and women who quietly work behind the scenes to protect this nation from the threat of terrorism. It’s not often that you get even a small glimpse into the vital role many of them play, yet for every investigation and every plot that is thwarted there are dozens, perhaps hundreds, who played a crucial role. One such group, Biowatch, is featured in a USA today article.
Behind the scenes, system sniffs for biological attacks
A ringing telephone startled Tom Slezak from a sound sleep. It was 1 a.m. on Oct. 6, 2001. The caller gave Slezak three hours to pack for a chilling, top-secret mission: to protect Washington, D.C., and other U.S. cities from a major bioterror attack.
For all Slezak knew, an attack had begun. Hours earlier, a Florida photo editor named Bob Stevens had died after inhaling anthrax powder sent by mail, jolting a nation that was still reeling from the 9/11 hijackings. At the time, the scope of the anthrax attacks that eventually killed five people and sickened 17 others wasn’t clear.
Slezak got the call because he helped pioneer the genetic analysis of biological agents at Lawrence Livermore National Laboratory in California. Today, eight years after the anthrax attacks, the system Slezak’s research team started, known as BioWatch, is quietly operating in more than 30 cities.
A federally funded, locally run program with an $80 million annual budget, it depends on a network of vacuum pumps that draw surrounding air through filters, sniffing for signs of biological agents.

The scenarios envisioned by Hooks and other Homeland Security officials are enough to keep anyone awake at night: A terrorist in a pickup in Charlotte, spewing a biological agent through an agricultural sprayer. A small plane releasing microbes into night skies upwind of Washington, D.C. Someone spraying anthrax from a briefcase in Pennsylvania Station in New York, the busiest transit hub in the USA, with 600,000 people streaming through each day.
“How many people would be infected? How far would it spread? They’d go right through there, jump on a train and be gone,” Hooks says. “Those are the kinds of things I worry about.”
The only way to know the detection system is capable of picking up such threats is to test it, says Omberg of Los Alamos. BioWatch analysts have released benign microbes upwind of likely terrorist targets and population centers. BioWatch sensors in the Washington, D.C., area have reliably picked up bacteria released near the Pentagon and Tysons Corner, a close-in office and retail hub in Virginia.
Real-world alerts, such as the tularemia incident in Washington, D.C., also have helped some cities gear up for a biological incident. Houston, even more than Washington, is home to the bacteria that cause tularemia, Francisella tularensis, which regularly triggers BioWatch alerts.Read the full article
