AquaBlok+(TM) Remediation Technology Wins 2007 Innovation Award at International Environmental Conference

LONDON, May 8, 2007 - The Adventus Group, implementers of field-proven remediation technologies
for soil, sediment and groundwater, announced today that its Funnel & Gate Design for the Capping and In Situ
Treatment of Impacted Sediments won the coveted "2007 ICU Innovation Award". This accolade is presented
annually at International Clean-Up (ICU) in Birmingham, England; the U.K.'s premiere contaminated land
solutions conference and exhibition.
Joanna Moreno, Adventus Director of Groundwater Services, was present to receive the award, "On
behalf of my colleagues at AquaBlok and Adventus, we are delighted with this recognition of the solid
science behind AquaBlok+. The international market potential is very high, and there is great value in
receiving such a commendation from recognized industry experts - including scientists, consultants and
investors."
"We'd like to thank the judges for doing their homework this year; they can feel confident in their selection
as Adventus prides itself on offering only scientifically defensible, proven biotechnologies designed to
economically address significant environmental challenges," Moreno added.
The Environmental Challenge Outlined
Sub-aqueous sediments may be physically capped to protect the overlying water and biota from
continuing contamination. However, permeable caps may not be protective for the required lifetime and
are difficult to monitor. Low-permeability caps may alter the natural flow system, potentially divert
contaminants in an unpredictable manner, and, in some cases, need to be vented to address gaseous
disruption.
The winning new technology, AquaBlok+, combines two well-established and proven technologies: zerovalent
iron (ZVI) and low-permeability capping with the AquaBlok delivery vector to address these
problems. The intellectual property is a collaboration between researchers at The Adventus Group and
AquaBlok Ltd. The technology is analogous to funnel and gate systems that have been implemented at
multiple sites for groundwater plume remediation. Various reactive gate materials have been developed
and tested in the laboratory. Modeling analyses of funnel and gate designs for a range of typical, fullscale
subsurface sediment capping conditions have been conducted. A pilot test in the Anacostia River,
Washington, D.C., in conjunction with the U.S. EPA, Battelle, and the University of Texas is taking place
during 2007.
Benefits Summarized
Funnel and reactive gate technology provides:
o isolation of contaminated sediment
o contaminant treatment
o better protection than sediment removal or non-reactive cap
This patented technology is applicable to:
o contaminated sediments
o contaminated groundwater discharging into water bodies
o contaminated water bodies recharging groundwater
o wide range of contaminants
Costs are available upon request, but generally on an order of magnitude less expensive than dredging
and ex-situ sediment management. Longevity of the capping material is indefinite, whereas for the
reactive gate material, greater than 10 years. They can also be reapplied as necessary.
