A hydrogeological case study at the abandoned Hindhede Granite Quarry examined groundwater seepage, water balance, rate of water level change and attempted to predict the final water level in the quarry. In August 1996, the water level in the quarry was at about +14 m MSL, while the general ground-water level in the vicinity was at about +25 m MSL. The present water level in the quarry pit is increasing at about 3.5 m/year. It will decrease gradually in future years. The water level will reach the rock head at +35 m MSL in 6 to 12 years depending on the prevailing climatic conditions.
