IRVINE, CA / CANBERRA, AUSTRALIA—July 22, 2021–Montrose Environmental Group, Inc. (NYSE: MEG) today announced that its subsidiary, Emerging Compounds Treatment Technologies, Inc. (“ECT2”), has renewed its contract for five years with the Australian Department of Defence [“Defence”] to operate and maintain water treatment systems at three of the country’s military bases. The $US43 million (AU$59 million GST inclusive) contract carries an initial term of five years and provides for an additional five extensions each for one year in duration, to be determined at Defence’s discretion and subject to ongoing needs at each military location.

In 2016, Defence engaged ECT2 for the removal of per- and polyfluoroalkyl substances [“PFAS”] from water at RAAF Base Williamtown in New South Wales, and Army Aviation Centre, Oakey in Queensland. The following year the company was awarded new contracts for an additional water treatment system for Williamtown and two treatment systems at RAAF Base Tindal in the Northern Territory. The five-year contract renewal comprises these three primary military bases, as well as the interim water treatment system at the Katherine Power and Water Corporation site in Katherine, Northern Territory.

ECT2’s specialized regeneration technology sees PFAS-laden resin regenerated for continuous use, minimizing waste generation that would otherwise be sent to licensed thermal destruction facilities for further management, or to landfill for future generations to contend with. To date, ECT2 has successfully treated over 5 billion liters of surface and ground water across Australia, ensuring that PFAS concentrations in treated water consistently remain below the recommended Australian health-based guidance.

The new contract began on July 13, 2021 with ECT2 confirming that it will continue to support remote and regional employment with its workforce of operators, administrative, technical and management personnel, drawing from the local community in each of the locations.  ECT2 today employs 19 workers in the local communities in direct support of its work with Defence.
