wow, here is another urban terrorist vulnerability i hadnt heard of
before. and the fires around sydney australia, more than half thought
to be started by arsonists, have made the point very clear that
whatever can be used as an anonymous weapon against one's neighbors,
will be used.

'Backflow' water-line attack feared
Terrorists could reverse flow in system to introduce toxins
By Yochi J. Dreazen
THE WALL STREET JOURNAL
Dec. 27 - In St. Petersburg, Fla., water authorities are keeping a closer eye on system-wide water pressure. In Cleveland, officials are weighing whether to add more chlorine to their water so larger amounts of the chemical will linger in their pipes. In Portland, Ore., alarms are now triggered by smaller drops in water pressure than in the past.
ACROSS THE COUNTRY, water utility officials are taking steps to prevent terrorists from reversing the flow of water into a home or business - which can be accomplished with a vacuum cleaner or bicycle pump - and using the resulting "backflow" to push poisons into a local water-distribution system.
Such an attack would use utility pipes for the opposite of their intended purpose: Instead of carrying water out of a tap, the pipes would spread toxins to nearby homes or businesses.
Water utility officials say the backflow threat dominates their post-Sept. 11 discussions with law-enforcement personnel. Although utilities have posted extra guards to patrol reservoirs and treatment plants, officials say the biggest threat to the nation's water supply may be from the pipes that carry the water, not facilities that store or purify it.��
