Modified after from Daniel (1990a). 4.7 Effects on other Groundwater Users The Wharekirauponga deposit is located beneath DoC land some distance from any groundwater users and is too distant to be able to influence other groundwater users given the limited extent of the drawdown effects predicted. We consider the potential for effects on other groundwater users from the proposed dewatering to be less than minor. 4.8 Ground Settlement Effects The primary rockmass being dewatered is the Rhyolite body and this is a hard, incompressible medium and is not expected to consolidate significantly as a result of dewatering. This has been assessed in detail in the EGL report (WAI-985-000-REP-LC-0050). 4.9 Effects on Plant Growth As stated in section 4.2, it is the Regolith soil water balance that determines the moisture content in the soils and therefore the capacity to support plant growth. The soil Regolith is the rooting zone where plants and trees source water to grow as shown in Figure 34.
