Discharge of weathering products from acid sulfate soils after a rainfall event, Tweed River, eastern Australia

MacDonald, Bennett; White, Ian; Astrom, Mats; Keene, Annabelle; Melville, Michael D; Reynolds, Jason K


The oxidation of the iron sulfide, pyrite, in acid sulfate soil floodplains generate substantial acidity and this acid has caused further weathering of the soil profile. The movement of groundwater from these soils is an important geochemical control on surface water quality. The flux of acidified and metal-rich water during a wet season rainfall event has been examined at two study catchments on the Tweed River in eastern Australia. At the sites, 81 kg/ha and 60 kg/ha of oxidisable acidity are...[Show more]
