Iraq

Business Editors

PASADENA, Calif.--(BUSINESS WIRE)--Aug. 25, 2003--Tetra Tech, Inc.
(Nasdaq:TTEK) announced today that it was assigned $65 million of work
to provide services for the U.S. government mission to revitalize Iraq.
The work will be conducted under the Worldwide Unexploded Ordnance (UXO)
contract with the U.S. Army Engineering and Support Center, Huntsville,
Alabama. Work is scheduled to begin immediately and will be conducted
over the next 12 months on a time and materials basis. This is the
largest single work assignment the Company has ever received.

Tetra Tech will receive captured enemy munitions from U.S. military
personnel, determine whether the munitions are serviceable or
unserviceable, and destroy selected munitions. The remainder of
munitions will be stockpiled under U.S. control until further
disposition is determined.

Li-San Hwang, Tetra Tech's CEO, stated, "We thank the Corps of Engineers
for entrusting us to support this critical mission. Tetra Tech's
expertise in hazardous materials management will help to make Iraq safer
for everyone."
