Water Chemistry

  • Keith Nicholson


The most common type of fluid found at depth in high-temperature geothermal systems is of near-neutral pH, with Chloride as the dominant anion. Other waters encountered within the profile of a geothermal field are commonly derived from this deep fluid as a consequence of chemical or physical processes. These waters, the characteristics of which are described below, are classified according to the dominant anions. Although not a formal genetic scheme, this descriptive Classification does permit some generalisations to be made on the likely origins of the waters. Examples of the composition of the different water types are given in Table 2.1.
