REFERENCE DOCUMENTS - RAL25/0004 (As Published)

                    •    Collection of one groundwater sample from each viable bore being MB1, MB2 and MB4 (plus a
                         duplicate and trip blank for QA purposes) via bailer technique (purge water disposed of onsite in
                         grassed areas)
                    •    Metal samples were field filtered using a disposable syringe and single use 45µm filters
                    •    Samples were collected in adequately labelled and laboratory prepared sampling bottles with
                         appropriate preservation for each analyte to be tested

                    •    Samples were placed in a secure chilled container for transport to the laboratory.

        6.3.4.      GROUNDWATER SAMPLE ANALYSIS
                    All groundwater samples were analysed for:

                    •    TRH/BTEXN/PAH (plus volatiles for the trip blank water sample per QA requirements) (with silica gel
                         clean-up for TRH)
                    •    Ultra trace heavy metals (suite of 8) (note that due to no Cr VI detected in soil, groundwater
                         chromium was not speciated)

                    •    PFAS (super trace short suite)

                    •    SVOC
                    •    Total Dissolved Solids
                    •    Measurement of field parameters in all samples:
                         -    Temperature, pH, Eh, EC, DO
                         -    Field observations on turbidity, colour, odour and sheen.


        6.4.        SOIL AND WATER SAMPLES COLLECTED AND ANALYSED
                    The soil and water samples collected and submitted for laboratory analysis are summarised in Table 12
