Brownfield Summit 2020

12 May 2020 | London

About this stream

This year's Groundwater conference will provide a comprehensive overview of the regulatory and policy framework governing the quality and protection of groundwater, as well as the latest laboratory advances and monitoring techniques for better assessing the risks of groundwater contamination.
 

Topics to be discussed include:

​

• Achieving improved Detailed Quantitative Risk Assessment (DQRA) and Plume Characterisation

• Better understanding Groundwater Pollutant Fate and Transport in the sub-surface

• Understanding & managing NAPL for more accurate risk assessment

• Groundwater Flood Risk Management

• Managing PFAS / PFOS and Plastics Contamination in Groundwater

New Techniques & Practical Solutions for the Improved Characterisation, Risk Assessment
& Remediation of Groundwater

Registration & Refreshments

Successfully Deriving Robust Groundwater Risk Assessment Criteria that Meets Regulatory Requirements & Avoids Unnecessary Remediation

​

• Identifying specific information requirements from the outset to make risk assessment an integral part of the remediation options appraisal process:

  • understanding the importance of characterisation and what DWRA can and cannot do 

• Moving from a risk-based to a cost-benefit approach to groundwater risk assessment and managing this in-line with regulatory requirements 

• Overcoming challenges in developing robust and achievable remediation target concentrations:

  • deriving site-specific degradation rates

  • reducing uncertainty and differences in predicted vs actual concentrations

  • generating soil re-use criteria that are compliant with the Environmental Permitting Regulations for groundwater

• Providing compelling and justifiable evidence to enable regulators to “sign-off” a remedial options proposal:

  • how can this be achieved when using new, innovative technologies?

GWSDAT: A Tool for Analysing Groundwater Quality Data and Contamination Plumes to Achieve Optimum Groundwater Monitoring and Remediation

​

The GroundWater Spatiotemporal Data Analysis Tool (GWSDAT) is a user friendly, open source, decision support tool for the analysis and reporting of groundwater monitoring data. The software
can handle large data sets with multiple monitoring locations, variable sampling events, and differing chemical constituents. 

​

GWSDAT has been used extensively in the assessment of soil and groundwater conditions in numerous locations world-wide. This presentation will demonstrate its use as a tool to achieve optimum groundwater monitoring and remediation.

Wayne Jones, Principal Data Scientist, Shell

11:40

Assessing the Effects of Climate Change on Groundwater Contamination

​

Exploring how groundwater flow and the microbiology of contaminants changes with temperature increases and extreme fluctuations in rainfall, and how this can be accounted for in groundwater risk assessment.

Effectively Characterising a TCE Groundwater Plume to Complete a Remediation Pilot Trial Using In-Situ Bioremediation and Liquid Activated Carbon

Emma McAnaw, Senior Hydrogeologist, Golder Associates

Interactive Break-Out Session

​

This focused, interactive session runs cross-stream giving delegates the opportunity to discuss a key topic of interest to them in a more participative format with professionals working across different areas of brownfield risk assessment. Each session will be led by a facilitator who will lead the discussion and encourage maximum debate and sharing of ideas.

Optimising Remote & Continuous Monitoring Technology to Achieve Real-Time, Targeted Data Collection

​

• Exploring the cost-benefits of remote continuous monitoring in groundwater wells – case study​

15:35

Developments in BioGeoChemical Reagents for Treatment of Chlorinated Solvent and Pesticide Contaminated Waters: Research & Case Studies

​

Following two decades of the worldwide application of EHC® reagent to treat contaminated groundwaters and saturated soils by physical, chemical and microbiological means, two new reagents (EHC® Plus & GeoFormTM) have been introduced by PeroxyChem to the European & American markets; these combine multiple reaction pathways to adsorb, reduce & destroy particularly persistent chemicals.  This presentation will cover the detailed science behind the products' development, their provenance in bench scale results (in conjunction with groundwater and soils provided by, and monitored alongside, four US Consultants), and then provide early results from three applications in the UK & Italy over the past years.

​

Mike Summersgill, Technical Representative, UK & Ireland, PeroxyChem

16:00

Assessing & Managing the Risks and Liabilities Associated with Per - & Poly- Fluoroalkyl Substances (PFAS)

​

• Detailing the Regulatory position on PFAS – likely timescales and scope of any guidance and proposed screening values

• Detailing the products, compounds and key sites of concern relating to PFAS and associated chemicals

• Assessing the fate, transport and behaviour of these chemicals and appropriate risk assessment

• Exploring PFAS remediation options – UK and international examples
