Note on the analysis of a mineral water from the Otira Gorge

Research papers, Lincoln University

The sample of water referred to in the present note was collected by the writer on the 21st January, 1889, in the Otira Gorge, from a spring which is stated to have been first discovered shortly after the earthquake of the 1st September, 1888. From the results obtained this water might be termed siliceous and sulphurous. It is essentially different from the water from the Hanmer Springs, and pertains more to the character of the waters of the Rotorua district. It differs, however, from these waters in having only a portion of its carbonic anhydride replaced by silica, and in containing less dissolved matter.
