What spreads like gravel, or even free-falls nicely through the water column, and can seal *or* treat *or* both? Join John Collins for an overview of the innovative coated aggregate technology used at the Toronto Portlands site to build one of the largest horizontal contamination treatment layers – constructed both in the wet and in the dry – in Canadian history, and learn more about the far-flung applications for this unique family of materials.

John Collins has more than 25 years of experience in application of technology to address a range of environmental issues. He is currently General Manger of AquaBlok and has applied this composite particle technology for remediation at hundreds of sites over the past 15 years.
