Groundwater Monitoring EC Results for New Cheshunt Stage 2 Piezometers<br />
All EC results with the exception of BUNC44D appear to have stabilised (Figure 61). The EC in the stable<br />
bores likely shows EC directly influenced by the Hunter River. More historical data is required for accurate<br />
assessment of trends.<br />

Groundwater Monitoring SWL Results for Cheshunt Stage 2 Piezometers<br />
All SWL results with the exception of BUNC46D appear to have stabilised, showing minor fluctuations likely<br />
associated with water levels in the Hunter River (Figure 62). More historical data is required for accurate<br />
assessment of trends.<br />
