In 2021, SoBRA established a controlled waters and climate change subgroup to address the need to incorporate the effects of climate change into contaminated land risk assessments.
Climate change has the potential to significantly impact the predicted risks posed by land contamination in certain scenarios and whilst Cl:AIRE published a SUBR:IM bulletin on climate change, pollution linkages and brownfield regeneration back in 2007 there has not been any further published guidance for risk assessors in the UK on how to incorporate climate change considerations into controlled waters risk assessment over and above FAQ number 8 published in the Environment Agency’s Guiding Principles for Land Contamination (GPLC) Part 2 in 2010. SoBRA’s publication by the climate change and controlled waters sub-group sets out the current regulatory and guidance context, identifies current sources of authoritative information on climate change impacts for the UK, and sets out an approach for a qualitative appraisal of climate change impact at the Preliminary Risk Assessment stage, and a series of “What If” scenarios to be considered at GQRA. The report identifies the limitations that existing standard DQRA modelling software (such as RTM and ConSim) have when looking to model the short-term, transient nature of many climate change impacts, and recommends a series of steps to mitigate this in DQRAs.
SoBRA held a one-day workshop in June 2018 entitled on the Fine Tuning DQRA’s for the Water Environment. The objective was to identify common mistakes in controlled waters risk assessment and explore potential solutions. This report presents a written record of the discussions held during the Summer 2018 workshop.
In June 2018, the Society of Brownfield Risk Assessment (SoBRA), the Geological Society Contaminated Land Group and RemSoc delivered a conference targeted towards early careers learning. Its aims were:
To support technical excellence in the assessment, estimation & evaluation of risks and associated uncertainties from land affected by contaminants;
To encourage “good practice” in the practical application of risk assessment to support decisions regarding the appropriate management of land contamination; and
To facilitate and widen access to the dissemination of knowledge regarding land contamination risk assessment.
A commitment of this workshop has been the creation of a series of short tabular reports for each of the different discipline areas. We have produced three practical tips documents which include human health risk assessment, controlled waters risk assessment and vapour intrusion (include link).
