It would take a lot of effort, and there are far easier targets. These buildings are guarded, and the water tank is thick walled concrete.[/ vQUOTE]
Safe enough, hunh. Well, when it comes to the aforementioned risks, that's not good enough for me.
Human error happens and, if a terrorist manages to attack one of these on site storage facilities, the results would be devastating. Further, just a thick walled concrete tank won't stop folks with the kind of resources major terrorist organizations have.
Why would a terrorist stop at just making a few acres uninhabitable when he can kill thousands by poisoning our water or spreading some nasty disease....
Contaminating ground water isn't poisoning water? Cancer's just "some nasty disease"? News to me. :shock:
