basin. This is related in part to the low calcium contents of these waters. Figure 19 shows a plot of calcium and fluoride. It can be seen that most of the analyses lie below the line of calcium fluoride saturation as calculated from Aylward and Findlay (1965), with a few samples above. This may be a result of super-saturation, or of errors in the published value, as very low solubility products are difficult to determine. Fluorides above drinking water guidelines do not occur in water where the TDS is acceptable for potable water. Some of the marginal waters on the eastern side of the basin are unsuitable for stock because of high fluoride.
