Short description: This document sets out the three-tiered risk assessment process that has been designed to: • establish whether pollutant linkages between the contamination and the designated ecological receptors are likely to exist; • gather sufficient information for making decisions regarding whether harm to those receptors is, or could, occur. The risk assessment is preceded by a desk study that reviews information about the site and nature of the contamination to assess whether pollutant linkages are feasible. Tier 1 of the risk assessment is a screening step based on a comparison of chemical analyses of site soils with a soil screening value (SSV) for the contaminant of concern. Tier 2 uses a choice of tools (ecological surveys and biological testing) to provide evidence for harm to the receptors. Tier 3 seeks to attribute the harm to the chemical contamination.
