the key assumptions and data gaps associated with the derivation of HILs and establishes the exposure parameters that have the greatest implications for the resultant HILs. The uncertainty and sensitivity analyses provide a 'reality check' for the HILs and are also described in this Schedule.
The HIL values are the outcomes of this risk assessment process and are presented in Tables 2 and 3 in this Schedule.

1.5              Objectives
The scope and purpose for the derivation of the HILs was established during the NEPM review described in Section 1.1. The key objectives are:
    * to produce health-based soil investigation levels suitable for use in Australian contaminated land assessments
    * to produce HILs that are relevant for Australian land uses, environment, climate and population
    * to produce HILs with consistent and transparent derivation, including assumptions
    * to provide HILs for a list of priority contaminants as established by the NEPM review
    * to produce HILs that are based on relevant, up-to-date, reviewed toxicological research
    * to produce HILs using risk assessment methodologies that are consistent with Australian policy and best international practice.
