The potential drawdown impact on private bore owners should be less than predicted if these groundwater flow paths are demonstrated to be less permeable than assumed in the model.
Should drawdown reach the private shallow bores and wells, the potential of experiencing a reduced supply will depend on how far they are from A-Pit and Khao Mo, and how permeable the rock fractures are around A-Pit. The impact duration will depend on how long it takes for A-Pit to fill to a point where hydraulic gradients retum to outward-facing (off-site)
