7                   Reporting
This section provides information about the recommended structure and content of both a Preliminary ERA and Definitive ERA report. Comments on the contents of ERA reports were included in previous sections about Preliminary and Definitive ERAs. The following is intended as guidance only, as the structure and content of reports will be heavily influenced by site-specific issues as well as client and regulatory requirements. The basic intent of this guidance is to provide a logical structure in a report that will facilitate understanding of the outcomes of the risk assessment by the risk managers, decision-makers and other readers of the reports (for example, stakeholders).
The ERA report should have the following main components:
    * summary
    * table of contents
    * introduction
    * problem identification
    * receptor identification
    * exposure assessment
    * toxicity assessment
    * risk characterisation
    * uncertainty
    * conclusions and recommendations
    * references
    * appendices.
Some of the components of a report are self-evident (such as the table of contents, introduction and references) and will not be further discussed.

The level of ERA will also determine the degree of complexity and completeness of the information and data analysis in each of these sections.

7.1              Summary
The summary should include the following information:
    * the background to the site
    * the rationale and objectives for conducting the ERA
    * a description of the type of ERA conducted
    * a description of the elements of the risk assessment
    * a summary of the key conclusions of the risk assessment and recommendations arising from it.
The summary should be written in non-technical language and contain sufficient information to enable a non-technical reader to understand the approach and results of the risk assessment, independent of the rest of the document.

7.2              Problem identification
The problem identification section should include the following information:
    * the objectives of the risk assessment
    * DQOs and CSM considerations
    * the background to the events leading to the conduct of a risk assessment
    * the level of ERA being conducted
    * a site description and history
    * a summary of site information and data contained in any previous site assessment reports. This could include information about land use, site geology, soil contaminant concentrations and distribution, background concentrations, and regional and local hydrology
    * an evaluation of quality assurance/quality control data on any previous field measurements and laboratory analysis contained in site assessment reports
    * uncertainty estimates with respect to the site assessment data
    * identification of key contaminants of concern (based on site history and any previous site assessment reports)
    * conclusions that can be drawn about problem identification.

7.3              Receptor identification
The receptor identification section should include the following information:
    * ecological values to be
