Brownfield Risk & Remediation 2017
Regulatory & Planning Updates & Practical Solutions To Deliver Risk-Based, Robust & Achievable Contaminated Land Development
Developing a time- and cost-effective remediation strategy that is “fit for purpose” and satisfies new planning and regulatory requirements is vital in successfully developing brownfield land. Where contamination is present, having confidence in the information provided by a rigorous and justifiable risk assessment is essential to avoid unnecessary costs. Setting realistic remediation targets and evaluating all of the remedial options available, including new technologies, can save both time and money, whilst achieving greater certainty of results.
This popular annual event, held in London on 13 and 14 September will bring together regulators, consultants, remediation contractors and other industry experts working across the whole of the brownfield sector to discuss a wide range of issues within contaminated land risk assessment and remediation. The inter-linked nature of these two topics means that delegates attending both days of the conference will benefit from the most holistic view, however it is also possible to attend just day One or Two.
Join us and benefit from hearing regulatory updates and sharing first-hand experiences with your peers, enabling you to develop practical and cost-effective solutions to current remediation challenges.

14.10 A decade of large-scale enhanced reductive dechlorination; examining the evolution in the usage of a high-volume controlled-release electron donor substrate.
Using case studies from technology launch up to ongoing projects, this presentation will discuss the development in the understanding, design and application of a slow release carbon substrate used to provide the enhanced reductive dechlorination of halogenated compounds.
Created to treat large-scale plumes synonymous with problematic chlorinated solvent contamination, the technology was created to transport widely through the subsurface post-injection, whilst avoiding wash-out and still providing an effective and sustained treatment rate.
The presentation will cover the lessons-learned through application into a wide range of geological and geochemical settings across Europe and America, targeting a number of contaminants, with concentrations ranging from DNAPL to low dissolved phase. It will also discuss the merits of integration of enhanced reductive dechlorination with physical and chemical technologies in order to optimise treatment onsite.
