This second well into the confined aquifer was drilled to 117.5 metres completed with a well screen in an unconsolidated sand interval between 104.2 and 115.6 metres. A yield of 1 200 kl/day was obtained with potential for greater yields without lowering the pump intake. Although almost identical to Kalangadoo TWS No. 1, improved screen design and more rigorous development has made TWS No. 2 a far more efficient well. It should be used as the main production well with TWS No. 1 as the standby. Water salinity remained constant at 600 mg/l TDS about 150 mg/l higher than groundwater in the overlying Gambier Limestone aquifer. In this region, the head of the confined aquifer is about 14 metres below that of the Gambier Limestone, with potential for contamination particularly from drainage wells penetrating deeply into the Gambier Limestone.
