After 9-11 there was widespread concern about several vulnerable systems spread across America. There are power plants, large dams, long bridges. But most ubiquitous and highly susceptible are large regional and municipal water systems. With correct monitoring by sensors that are networked, now there can be rapid analysis of drinking water safety in these large, largely unguarded systems. And that software system was developed by a team of government technocrats. One part of the software suite is called CANARY. At the time no such software existed in the corporate world or in other countries. The government team developed another software program to help determine the best locations for the all-important sensors.
