        8.1.2.      AEC 2 – SOUTHERN RUBBISH DISPOSAL AREA
                    Six PSI test pits (TP6 to TP11) were excavated to a maximum depth of 1.1mbgl within the AEC 2 rubbish
                    disposal area that is located over the southern portion of the site. TP7 was extended to 15m length as a
                    transect. Evidence of fill and waste materials was identified at all locations, ranging from infrequent
                    predominately glass wastes at locations TP7 and TP11, to very frequent waste materials encountered at
                    locations TP6, TP8, TP9 and TP10.
                    Test pit TP6 located near the eastern site boundary (refer Photo 11) had frequent glass fragments within
                    the fill layer that extended to a depth of 0.25mbgl (refer Photo 12).

                    DSI works included the excavation of an additional 39 test pits over this area, which correlated with the
                    PSI works and sit history with respect to expected extent of the wastes and the central hotspot around
                    locations TP9, TP10 and TP50 that were observed to have the most frequent and mixed wastes
                    encountered, including:

                    •    Large to small cement sheeting fragments suspected of containing asbestos
                    •    Various scrap and waste metal items

                    •    Bottles and fragments of glass and ceramics, and

                    •    Household and electronic components (older style meat thermometer and a transistor or similar).
                    These wastes are present in a fill layer present to a depth of up to 0.6mbgl, with no evidence of
                    putrescible wastes identified. Selected images of the TP10 wastes are presented over page in Photos 13
                    through 16.
