Envirotreat Technologies Ltd was commissioned by Cognition Land and Water to design and install a Permeable Reactive Barrier at Phase 2 of the prestigious Royal Wharf development in Silvertown, London (located in close proximity to the Thames Barrier). The reactive barrier was installed to protect offsite receptors on the northern boundary of the site and was an extension of the barrier previously installed during the first phase of the development earlier in 2014. The contamination was primarily metallic in nature reflecting the historical use of the site as a munitions / chemicals factory. The barrier length was approximately 200m. The environmental consultants were Card Geotechnics Limited.
