JMAR Technologies Reports Positive Findings in EPA Tests of BioSentry Water Monitoring System

Business Wire, April 9, 2008

Product Outperforms All Alternative Technologies for Real-Time Pathogen Detection

SAN DIEGO -- JMAR Technologies, Inc. (OTCBB:JMAR), a leading developer of advanced laser, photonics and detection technologies, today announced the results of a testing program carried out by the U.S. Environmental Protection Agency (EPA) to measure the performance of JMAR's BioSentry monitoring system and competing products at detecting harmful microorganisms in drinking water distribution systems.

The U.S. EPA presented results at the AWWA Water Security Congress 2008 this week and the tests found that BioSentry was able to detect bacterial pathogens up to 25 times better than any other product tested. The published results can be found in the proceedings of the conference.

The program was carried out in 2007 by the EPA's National Security Homeland Research Center, using a pilot-scale water distribution system at the EPA's testing and evaluation facility in Cincinnati, Ohio. Tests were performed to determine the detection capabilities of BioSentry and other products against intentional introduction of pathogens into a water distribution system. Several pathogen surrogates were used simulating lethal microbes.

JMAR Technologies' President and CEO C. Neil Beer, Ph.D., commented, "As a matter of policy, the EPA does not endorse or promote specific products. However, the performance of our flagship product, BioSentry, in EPA's strictly objective testing program, speaks for itself. These results strongly reinforce our conviction that BioSentry will soon be in wide use around the world to protect the public from intentional or accidental contamination of water supplies. The success of BioSentry also bodes well for other products in development that employ similar advanced technology."
