EXTRACT:
This document provides guidance on decision-making activities at Tier 3 (the final tier)
of the Ecological Risk Assessment framework for contaminated soils. This tier requires
risk assessors to consider whether the adverse effects observed that signify harm at
the site under investigation can be attributed to the contaminants measured in the soil.
The guidance sets out a structured approach for assessing the attribution of the cause
to the effect, referred to as Hill’s Causal Criteria (Hill, 1965), and also proposes a range
of other options more commonly used in the aquatic environment that could potentially
be developed for soils.
The structured consideration of cause-effect attribution is intended to allow sites where
the harm in the ecosystem is due to a reason other than chemical contamination to exit
the framework at Tier 3, or to increase the strength of the evidence where harm is likely
to be attributable to those contaminants.
