The Boston subway system will soon host simulated biological weapon attacks as the Department of Homeland Security's Science and Technology Directorate (S&T) conducts tests of sensors designed to detect the presence of biological agents in metropolitan areas.
After temporarily shutting down the transportation system, S&T will release small quantities of harmless and inactive bacteria into subway tunnels under Beantown and monitor the spread of the dead microbes using newly developed sensors. The bacterium, Bacillus subtilis, is considered nontoxic even when alive and active.
S&T will be conducting the tests—which are part of its Detect-to-Protect (D2P) project—for the next 6 months, according to the Department of Homeland Security. Anne Hultgren, director of the D2P project, said that the tests will help determine if the new sensors, designed by a suite of contractors, are up to snuff. "While there is no known threat of a biological attack on subway systems in the ...
