Coal & Allied – Hunter Valley Operations Cheshunt Groundwater Cheshunt piezometers are sampled quarterly subject to safe access. Interpretation of Cheshunt groundwater has been previously based on stage one bore sites; BZ1(1-3), BZ3(1-3), BZ4A(1-2), BZ4B, BZ5(1-2), BZ8(1- 3), HG2, HG2A and HG3. Stage two bores installed into targeted Cheshunt Pit seams in advance of mining came on line in May 2008. Several of the bores contain multiple piezometers and provide water level and EC data as far down as the Bayswater seam. These new bores include sites BUNC44D, BUNC46D, CHPZ12A, CHPZ12D, CHPZ13A, CHPZ13D, CHPZ14A and CHPZ14D. Samples were unable to be collected from BC1, BZ1-2, BZ4B, BZ5-1, BZ5-2 and BZ8-1 as sites were reported as dry during the reporting period. December sampling was unable to occur as scheduled. As such a make up run was performed in January 2010. Monitoring results for 2009 are shown in Table 38 and Table 39 and in Figure 57 to Figure 62. A Groundwater Impacts Report for HVO South is provided in Appendix 10 in accordance with the HVO South Development Consent.
