        8.2.1.      TRH/BTEXN/PAH/SVOC/OCP/OPP/PFAS
                    Total Recoverable Hydrocarbons (TRH), Benzene, Toluene, Ethylbenzene, Xylenes and Naphthalene
                    (BTEXN), Polycyclic Aromatic Hydrocarbons (PAH), Semi-Volatile Organic Compounds (SVOC),
                    Organochlorine and Organophosphorus Pesticides (OCP/OPP) and Per-and poly-Fluoroalkyl Substances
                    (PFAS) were mostly not detected above the laboratory Limit Of Reporting (LOR) or were otherwise well
                    below relevant Site Assessment Criteria (SAC).
                    Whilst these potential contaminants were assessed as part of the detailed site assessment, they have
                    been found unlikely to be present such as to require further assessment or management.

        8.2.2.      AESTHETICS
                    The presence of unsuitable physical wastes, as discussed in 8.1 and summarised on Drawing 2, mostly
                    exceed SAC and requires remediation to progress removal of the site from the EMR. No unacceptable
                    odours were associated with any soil or fill material.

        8.2.3.      ASBESTOS
                    No Asbestos Fines (AF) or Fibrous Asbestos (FA) were detected, however, Asbestos Containing Material
                    (ACM) in the form of infrequent cement sheeting fragments are associated with the southern rubbish
                    disposal area at locations TP10, TP11, TP38 and TP55. These fragments are likely to be incidental
                    inclusions in the waste streams, and not indicative of more formal historical asbestos disposal activities.
                    This correlates with the broad usage pattern of asbestos cement sheeting in this part of Australia at the
                    time of the historical disposal occurring, with widespread asbestos use for construction emerging with low
                    potential for structural demolition involving asbestos.
                    The northern night soil disposal area is not associated with asbestos.

        8.2.4.      HEAVY METALS
                    Other than aesthetics and asbestos discussed above, locations or samples exceeding SAC are
                    associated with elevated heavy metals as shown on Drawing 2 and listed below:
                    •    TP2-0.5 – metals (copper) exceed SAC (deepest sample analysed)

                    •    TP7-0.1 – metals (zinc) exceed SAC (deepest sample analysed)
                    •    TP9-0.1 – metals (copper, lead, nickel, zinc) (underlying 0.3 sample below SAC)

                    •    TP10-0.1 – ACM and metals (zinc)

                    •    TP10-0.5 – metals (chromium, copper, lead, nickel, zinc, mercury) (underlying 0.7 sample below
                         SAC)
                    •    TP11-0.1 – ACM and metals (zinc) (underlying 0.5 sample below SAC)
                    •    TP13-0.1 – metals (zinc) (underlying 0.5 sample below SAC)
                    •    TP14-1.0 – metals (zinc) (samples at 0.1, 0.5 and 2.0 were below SAC)

                    •    TP21-0.1 – metals (zinc) (underlying 0.5 sample below SAC)
                    •    TP38-0.1 – ACM
