The Society of Brownfield Risk Assessment (SoBRA) has been established to support the growing number of professionals working in land contamination risk assessment. It is a learned society for individuals, with membership drawn from the private, public, voluntary and academic sectors. Its goals are to improve technical knowledge in risk-based decision-making related to land contamination applications and to enhance the professional status and profile of practitioners.

SoBRA’s core objectives:

  1. To support technical excellence in the assessment, estimation & evaluation of risks and associated uncertainties from land affected by contaminants.
  2. To encourage “good practice” in the practical applications of risk assessment to support decisions regarding the appropriate management of land contamination.
  3. To facilitate and widen access to the dissemination of knowledge regarding land contamination risk assessment.
  4. To form relationships and work in a constructive manner with other organisations and professional bodies involved in land contamination and remediation, as well as the environmental sciences in general.
  5. To assist in the development of future guidance, either through coordinated responses to consultation documents or by providing direct input to guidance.
  6. To identify areas of future research that would benefit the assessment of land contamination.
  7. To co-ordinate and encourage such research and, where appropriate, explore funding arrangements to support it.


SoBRA is a not-for-profit society. It is run on a voluntary basis, by a democratically elected committee. Membership is open to any individual who is involved in, or has an interest in, land contamination risk assessment. The membership fee is reviewed on an annual basis at the AGM. Fees are used to pay for administrative charges and for supporting and promoting the Society’s interests.


Society member meetings are the principal forum for information exchange regarding “good practice” in risk assessment. The objective is to hold a minimum of two meetings each year typically comprising a one day workshop in the summer, and a one day conference/AGM in December.
