Rain leaches alkaline elements including calcium, magnesium and potassium from the soil into runoff water, leaving acidic elements like hydrogen, aluminum and manganese to replace the bases. When the surface temperature of the water rises, the solubility of carbon dioxide will decrease so that the pH will rise and the water is alkaline. If water has a high enough concentration of carbonate and bicarbonate ions, the pH will change. :(. This fluctuation occurs primarily because of changes in salt levels in the soil.
