CGI Federal, Inc., a wholly-owned U.S. operating subsidiary of CGI Group Inc., (NYSE: GIB; TSX: GIB.A) has partnered with the U.S. Environmental Protection Agency (EPA) Office of Research and Development (ORD) to develop a comprehensive Drinking Water Treatability Database (TDB). The database will be a publicly accessible website containing referenced data on the control of over 250 drinking water contaminants, by more than 30 water treatment processes. The information will be gathered by environmental consultants from a variety of peer publications, research reports, conferences, and other literature sources. The EPA envisions the TDB as a compendium of water treatment research assembled in a single location which can be easily accessed by the water treatment community.

CGI worked with ORD to design the TDB and developed both the public application as well as a web-based data entry tool where ORD and environmental consultants can compile research data.

"The TDB will be a useful tool for making drinking water treatment data available to the water utilities, design engineers, first responders, researchers and regulators. It will provide the effectiveness of various treatment processes for removing contaminants from drinking water, and the conditions of their effectiveness. Where data are limited, it will identify research needs," said Dick Miltner, an EPA environmental engineer with ORD's Water Supply and Water Resources Division in Cincinnati, Ohio, who manages the TDB.

"The EPA has been a customer of CGI for over 30 years, and we are excited to be their partner in the development of this valuable application," said Kenyon Wells, Vice- resident, CGI Federal. "We are pleased that the EPA has the confidence in our company to develop critical scientific applications like the TDB and look forward to working with the EPA laboratories in the future to create useful tools for the scientific community."

The Water Treatability Database is available at www.epa.gov/tdb.
