| Abstract | Pre-commissioning monitoring of surface features at Ngawha from 1996 to 1998 generally supports the fhdings of Sheppard and Johnston (1984) in terms of temperature, mass flow rates of chemical species in solution, and gas species discharged. Although the behaviour of Universal Bath remained relatively constant a significant decrease in the chloride content was found compared to historical data. Over the two years of power generation (1998 to 2000) the variability of the above parameters and the total deep reservoir fluid discharged at the surface of the Ngawha Springs locality are similar to baseline values. |
