Scientists with the Environmental Protection Agency have collaborated with the Department of Energy to develop new water quality software that enhances a local water system's ability to know when it's been intentionally, or unintentionally, contaminated. It assists both agencies in meeting goals connected to homeland security.

Utilities can use the Canary software - in conjunction with a network of sensors - to quickly detect contamination, more accurately assess when and how to respond, and then issue warnings to customers if necessary.

The software can help detect chemical and biological contaminants, including pesticides, metals, and pathogens.

Canary is available worldwide as a free software tool to drinking water utilities. The software is currently being used by more than 600 users in 15 countries.
