Natural waters of the Queensland coastal belt

Abstract

1. A number of natural waters have been examined, some by complete analysis and others by partial analysis; the methods are given in detail, with notes on cloudy waters.
2. The data are presented in terms of various ionic ratios, and in comparison with the two great divisions of natural water - the ocean and the great rivers of the world.
3. Compared with those of the great rivers, the waters of the Queensland coastal area exhibit a low ratio of calcium to magnesium, of divalent to monovalent bases (cations), and of bicarbonate to chloride. All these anomalies reflect oceanic influence.
4. The application of the data to boiler feed supply is discussed briefly. It is concluded that silica in not unduly high for tropical conditions.
