Although for practical reasons, terrorist attacks on water systems are considered less likely than on other targets, threats to drinking water cannot be ignored. A large-scale chemical sabotage of drinking water, even insufficient to cause casualties, could still have disastrous socio-economical consequences. There is therefore a need to maintain a high-level of security around water treatment and distribution facilities, especially those supplying critical infrastructures, and to develop emergency preparedness programs at both the local and national levels.
