Chemistry of the Bogan River, New South Wales, with Special Reference to the Sources of Dissolved Material

Abstract

The chemistry of the Bogan River was studied, and the chemical variation along the river and the origin of the ions are discussed. Ionic dominances were: Na⁺ ≈ Ca²⁺ ≈ Mg²⁺; HCO₃^- > Cl^- > SO₄^2-. The contribution of salt from the sea, from dust and from soils has been assessed using a residual method. Atmospheric precipitation appears to be the main source of salts.
