Full analysis and discussion of these results will be presented in the comprehensive 2014 Annual Report which will detail all groundwater and surface water level and quality results from the 2013/14 monitoring period (to be submitted September 2014). For the period: low level probes were installed (on 03/12/13) at TSW01 and ASW01 below the zero height level of the gauge boards to capture data during periods of low river flow. Three Vibrating Wire Piezometers (VWP’s) were installed in the former corehole PL03. Only the two shallowest VWP’s are operational. New monitoring sites became operational at Fauklands (2 bores) and Bucketts Way (4 bores) near Gloucester. Figures 1 - 6: Groundwater hydrographs for Stage 1 and 2 nested monitoring bore sites Figure 7: Surface water levels and EC comparison of all monitoring sites Figures A-1 – A-31: Individual Stage 1 groundwater monitoring bore hydrographs Figures A-32 – A37: Individual Stage 2 groundwater monitoring bore hydrographs Figures A-38 – A-45: Individual surface water level and EC monitoring hydrographs Figures A-46 – A-48: PL03 (Pontilands) VWP hydrographs Table 1 shows quarterly shallow gas monitoring results from TGMB01 and TGMB02 on the Tiedman property.
