Scientists from the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE) have collaborated in developing innovative water quality software that enhances a water system's ability to detect when there has been intentional or unintentional contamination. The Canary software can help detect a wide variety of chemical and biological contaminants, including pesticides, metals, and pathogens. Once contamination is detected quickly, a water utility can issue a "Do Not Drink" order to prevent customers from ingesting the water.
