Southern Cross Operations Annual Environmental Report 2008 - 2009

2009 Annual Environmental ReportSouthern Cross OperationsGroundwater LevelsPiezometric levels are discussed in section 5.1. Groundwater levels of boressurrounding the Marvel Loch TSF have been relatively static over the past year. BoresMB94E1 and MB94G1 have shown a slight increasing trend with readings of 0.34mand 0.4m respectively. MB94D1 has shown a slight decreasing trend with a reading of0.28m and MB94F1 remained constant. As shown in the graph, a value of 5.61m wasrecorded for MB94D1 on 20 December 2008, it is believed that this value wasincorrectly recorded and should have been 4.61m, as shown by the “correction” line onthe graph. This correction is supported by the slight decreasing trend of the bore andconfirmation with the operator that the “5” instead of a “4” is a likely error.Figure 7-4: Groundwater Levels of Bores at the Marvel Loch TSFGroundwater Abstraction LicencesDuring the year groundwater abstraction occurred at SXO under the terms of the threeLicense to Take Water licences, Marvel Loch Operations 59227(3) (Lake Baladjie toYilgarn Star), Southern Star/Toomey Hills (104620(4)) and Blue Haze/Kondinin-Ravensthorpe (153325(3)).
