In geothermal water research also, the need of quality control and analytical consistency among geochemical laboratories was recognised long ago, when Ellis (1976) conducted the first inter-laboratory comparison of the quality of geochemical analysis in waters, organized by the International Association of Geochemistry and Cosmochemistry (IAGC).
