Oak Ridge Tennessee, January 07, 2005 — A technology to instantly determine a poisoned water supply system has been developed at the Department of Energy's Oak Ridge National Laboratory.

Researcher Eli Greenbaum said the AquaSentinel system can detect toxins in a municipal water supply by analyzing the condition of the algae it contains.

"Depending upon whether the water is healthy or it has been exposed to poison, the fluorescence signature changes," said Greenbaum of ORNL's Chemical Sciences Division. "It is that change in signature that we use as the detection method for detecting the presence of chemical warfare agents."

Greenbaum noted AquaSentinel can monitor a water supply 24 hours a day, seven days a week.

"The way AquaSentinel works is that based on the fluorescence from the algae that are already in the water, and the fact that the algae already live in the neighborhood of the environment that we are trying to protect, we never run out of biosensors," Greenbaum said.

ORNL is managed by UT-Battelle for the Department of Energy.
