Both the Department of Health and an accredited contaminated sites auditor reviewed the report, with the latter finding that the detected presence of free asbestos fibres in surface soils from sampled locations presented an unacceptable public health risk. The auditor recommended that the former townsite and other impacted areas defined in the report be classified as "Contaminated - Remediation Required". The Department of Environment and Conservation subsequently classified Wittenoom as a contaminated site under the Contaminated Sites Act 2003 on 28 January 2008.[1][2]
