It's not easy to contaminate a water supply to the point where it would present a serious threat.
Basic faq here
Contamination of a reservoir with a biological agent would be unlikely to produce a large risk to public health, simply because of the dilution
effect. These reservoirs contain hundreds of thousands and in some cases millions of gallons of water. Very simply, it would take a massive amount
of contaminant to produce a viable threat at this stage; if the contaminant agents were to be introduced at this point they are likely to be detected
and unlikely to survive the chlorination process....
However, if the point of contamination is after
a treatment facility the likelihood of success is much greater. Again though, this would be
subject to dilution, which would greatly lessen the effects.
To be honest, I think we'd be subject to a far greater risk from hacking into the computers controlling the water systems....that
something to worry about.
It would appear to be much easier for a terrorist to obtain access to a storage facility holding bottled water, for example, and contaminating the
