Drawdowu data from the plliuping a~d observation bores are presented in Figures 4.3 and 4~4 The drawdown cone created by pumping inte~sected or distinct. aquifer boundary at approximat.ely 400 minutes pumping. This caused a reduction in effective transmissivity from 76 to 44 m2 /d. Storage coefficient values calculated f~om the observation data ~"Iere lo~w (4.25 x 10 3 ) but the reliability is doubtful due to the high transmissivity value obtaL~ed using the curve matching technique. Based on projection of the present drawdown trend, bore W4 is capable of rnaintainir.g a discharge of 2 l/sec.
