Adventus Group and EnviroMetal Technologies Announce Merger.

MISSISSAUGA, Ontario -- International Provider of Biotechnology-Based Remedial Solutions Acquires Permeable Reactive Barrier Expertise

Adventus Remediation Technologies, Inc. (ART), a rapidly growing innovator of remediation biotechnologies for soil, sediment and groundwater, and its U.S. subsidiary Adventus Americas, Inc. (AAI), have announced their merger with EnviroMetal Technologies Inc. (ETI). ETI's permeable reactive barrier (PRB) technology will now be available through a number of regional offices in North America. ETI's many clients will also have access to the products and services available through the Adventus Group of companies, including PRB media for contaminants not currently treated by iron PRBs. Customers include the U.S. military, public utilities, commercial real estate ventures, chemical companies and numerous other site owners who seek rapid, cost-effective, and thorough removal of toxic contaminants. The groups' combined portfolio consists of more than 200 site installations across North America, Asia, Europe and Australia.

Dr. Alan Seech, president and CEO of ART, stated, "Adventus has grown rapidly since our formation in July 2002. Joining forces with the world-renowned professionals at ETI, and adding their patented PRB treatment technologies to our portfolio of remediation solutions will greatly benefit our current and future customers who demand advanced technologies for their most challenging projects. Furthermore, the collaborative research program supported by both our firms and the University of Waterloo during this past year has now yielded 'second generation' reactive materials which will further expand the scope of ETI's and Adventus' range of groundwater treatment capabilities."

ETI President John Vogan said, "ART's and AAI's U.S. and international network will significantly increase the awareness level and application rate of our core technology. Moreover, the R&D strength of the merged companies will accelerate the introduction of promising new treatment materials and techniques into the marketplace. This will greatly expand the scope of in-situ groundwater and soil treatment services we can offer. On behalf of the entire team at ETI, we are pleased to be an integral part of this committed group of environmental science experts, and we eagerly look forward to delivering even greater value to our clients through an expanded range of product and service offerings."
