This short document summarises the SuRF-UK indicator categories following their further development and refinement in worked case studies and discussion groups. A description of 15 categories of indicators spread over environmental, social and economic factors that can be used for sustainability assessment in support of remediation decision-making is presented. This short document describes the function of these categories, their development and how they can be used to support the SuRF-UK Framework and the Key Principles underpinning sustainable remediation that this framework identifies.
